  Applied innodb-5.1 snapshots ss799 and ss854
  
  Revision r823:
  Minor cleanup related to Bug #20877.
  
  btr_print_recursive(): Replace tree->tree_indexes with tree->index.
  This should have been done in r453.
  
  univ.i: Add UNIV_BTR_PRINT.
  
  rw_lock_t: Reduce writer_is_wait_ex to a bit and move it close to
  other bitfields.  Change the types to unsigned, in case ulint or ibool
  bitfields will not work.
  
  
  Revision r828:
  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256
  bytes on 64-bit systems).  (Bug #20877)
  
  struct dict_tree_struct, dict_tree_t: Remove.
  
  struct dict_index_struct: Add page and lock.
  
  dict_tree_create(): Remove.  Replace the invocation with
  assignment to index->page and a call to rw_lock_create(&index->lock).
  
  dict_tree_free(): Remove.  Replace the invocation wtih
  a call to rw_lock_free(&index->lock).
  
  dict_index_get_tree(): Remove.
  
  dict_tree_get_space_reserve(): Rename to dict_index_get_space_reserve()
  and remove the parameter, which was unused.
  
  btr_level_list_remove(): Remove the unused parameter "tree".
  
  Replace the occurrences of "tree" with "index" in names of variables,
  functions and data types, e.g. "dict_tree_t tree" becomes
  "dict_index_t index".  Remove local variables "tree" or "index" of
  functions that needed both "tree" and "index".
  
  
  Revision r834:
  dict_col_t: Copy the fields of "dtype_t type" directly to this structure,
  so that all integer fields can be packed into 64 bits.  (Bug #20877)
  
  dtype_t: Change the type of all bit-fields to unsigned.
  
  dict_table_get_nth_col(), dict_table_get_sys_col_noninline(),
  dict_table_get_sys_col(), dict_field_get_col(): Return const
  dict_col_t*, so that changes to dict_col_t can be detected more
  easily.  Add const to many dict_col_t* declarations.
  
  dict_index_get_nth_type(): Replace with dict_index_get_nth_col().
  
  dict_col_get_type(): Replace with dict_col_copy_type().
  
  dict_col_get_min_size(), dict_col_get_max_size(), dict_col_get_fixed_size(),
  dict_col_get_sql_null_size(): New functions.
  
  dtype_get_at_most_n_mbchars(): Replace the parameter dtype
  with the parameters prtype, mbminlen, mbmaxlen.
  
  dtype_get_pad_char(), cmp_data_data(), cmp_data_data_slow(),
  cmp_whole_field(): Replace the dtype_t* parameter with the ulint
  parameters mtype, prtype.
  
  dtype_copy(): Add a const qualifier to type2 (the one being copied from).
  
  dtype_set_mblen(): Replaced with dtype_get_mblen().
  
  dtype_get_fixed_size_low(), dtype_get_min_size_low(),
  dtype_get_fixed_max_low(): Replace dtype_get_fixed_size(),
  dtype_get_min_size(), and dtype_get_max_size().  These are used by the
  dict_col_get_{fixed,min,max}_size() functions.
  
  cmp_types_are_equal(): Replace with cmp_cols_are_equal().
  
  dict_table_get_col_name(): Add a const qualifier parameter to the
  parameter "table".
  
  dtype_binary, dtype_binary_val: Remove.
  
  dtype_is_fixed_size(): Remove.
  
  
  Revision r837:
  page_offset(): New function to replace many ut_align_offset(., UNIV_PAGE_SIZE)
  calls.
  
  dict_index_build_node_ptr(): Correct a typo in a comment.
  
  
  Revision r838:
  Revamp the line splits done in r763 and r764 that can now be done better,
  thanks to r826.

  Revision r813:
  Reduce the size of the data dictionary cache.  (Bug #20877)
  
  dtype_t: Remove unused field "prec", which was supposed to be used for
  the precision of decimal columns in stand-alone InnoDB.
  
  dtype_get_prec(): Remove.
  
  dtype_set(), dict_mem_table_add_col(): Remove parameter "prec".
  
  dtype_t: Turn all fields (mtype, prtype, len, mbminlen, mbmaxlen, len)
  into bit-fields.
  
  dict_table_t, dict_index_t, dict_tree_t: Omit magic_n from non-debug builds.
  
  dict_col_t: Turn ind, clust_pos, and ord_part into bit-fields.
  
  Replace the default clust_pos value ULINT_UNDEFINED with
  REC_MAX_N_FIELDS and replace all references to clust_pos with calls to
  the accessor function dict_col_get_clust_pos().
  
  dict_field_t: Turn prefix_len and fixed_len into bit-fields.
  
  dict_tree_t: Remove pad[64].
  
  dict_table_t: Turn the fields ibd_file_missing, tablespace_discarded,
  cached, flags, stat_initialized, and autoinc_inited into bit-fields.
  Remove does_not_fit_in_memory from non-debug builds.
  
  dict_index_t: Turn the fields trx_id_offset, n_user_defined_cols,

  Revision r824:
  Reduce the size of btr_search_t from 13 machine words to 7.  This
  structure is reserved for every index in the data dictionary cache.
  (Bug #20877)
  
  We could shrink the structure further to three 32-bit words or two
  64-bit words by turning the remaining fields to bit-fields.
  Unfortunately, the fields are not protected by any mutex, and thus we
  would better keep each field aligned to a machine word.

  Revision r832:
  Add dict_table_get_col_name() in preparation for getting rid of
  dict_col_t::name, and use it instead of col->name everywhere.
  
  Revision r833:
  Tweak the bit-field definitions introduced since r813 to address Bug #20877.
  
  rw_lock_t: Do not make writer_is_wait_ex a bit-field.  There are no fields
  yet that could be fused to the same machine word, but we play it safe,
  because the field writer_is_wait_ex may be modified by several threads
  simultaneously.  Such fields should always be allocated an own machine
  word.
  
  dict_table_t: Change the type of all bit-fields to "unsigned".  Make
  "space" a bit-field of 32 bits.  Move name_hash and id_hash after all
  bit-fields, so that the bit-fields can be allocated together.  Do not
  make autoinc_inited a bit-field, as we cannot allocate any field
  from the same machine word.
  
  dict_build_table_def_step(): Pass a local variable to
  fil_create_new_single_table_tablespace() and initialize table->space
  from it after the call, now that table->space is a bit-field.
  
  
  Revision r834:
  dict_col_t: Copy the fields of "dtype_t type" directly to this structure,
  so that all integer fields can be packed into 64 bits.  (Bug #20877)
  
  dtype_t: Change the type of all bit-fields to unsigned.
  
  dict_table_get_nth_col(), dict_table_get_sys_col_noninline(),
  dict_table_get_sys_col(), dict_field_get_col(): Return const
  dict_col_t*, so that changes to dict_col_t can be detected more
  easily.  Add const to many dict_col_t* declarations.
  
  dict_index_get_nth_type(): Replace with dict_index_get_nth_col().
  
  dict_col_get_type(): Replace with dict_col_copy_type().
  
  dict_col_get_min_size(), dict_col_get_max_size(), dict_col_get_fixed_size(),
  dict_col_get_sql_null_size(): New functions.
  
  dtype_get_at_most_n_mbchars(): Replace the parameter dtype
  with the parameters prtype, mbminlen, mbmaxlen.
  
  dtype_get_pad_char(), cmp_data_data(), cmp_data_data_slow(),
  cmp_whole_field(): Replace the dtype_t* parameter with the ulint
  parameters mtype, prtype.
  
  dtype_copy(): Add a const qualifier to type2 (the one being copied from).
  
  dtype_set_mblen(): Replaced with dtype_get_mblen().
  
  dtype_get_fixed_size_low(), dtype_get_min_size_low(),
  dtype_get_fixed_max_low(): Replace dtype_get_fixed_size(),
  dtype_get_min_size(), and dtype_get_max_size().  These are used by the
  dict_col_get_{fixed,min,max}_size() functions.
  
  cmp_types_are_equal(): Replace with cmp_cols_are_equal().
  
  dict_table_get_col_name(): Add a const qualifier parameter to the
  parameter "table".
  
  dtype_binary, dtype_binary_val: Remove.
  
  dtype_is_fixed_size(): Remove.
  
  
  Revision r838:
  Revamp the line splits done in r763 and r764 that can now be done better,
  thanks to r826.

  the precision of decimal columns in stand-alone InnoDB.
  
  dtype_get_prec(): Remove.
  
  dtype_set(), dict_mem_table_add_col(): Remove parameter "prec".
  
  dtype_t: Turn all fields (mtype, prtype, len, mbminlen, mbmaxlen, len)

  dict_table_t, dict_index_t, dict_tree_t: Omit magic_n from non-debug builds.
  
  dict_col_t: Turn ind, clust_pos, and ord_part into bit-fields.
  
  Replace the default clust_pos value ULINT_UNDEFINED with
  REC_MAX_N_FIELDS and replace all references to clust_pos with calls to
  the accessor function dict_col_get_clust_pos().
  
  dict_field_t: Turn prefix_len and fixed_len into bit-fields.
  
  dict_tree_t: Remove pad[64].
  
  dict_table_t: Turn the fields ibd_file_missing, tablespace_discarded,
  cached, flags, stat_initialized, and autoinc_inited into bit-fields.
  Remove does_not_fit_in_memory from non-debug builds.
  
  dict_index_t: Turn the fields trx_id_offset, n_user_defined_cols,
  n_uniq, n_def, n_fields, n_nullable, and cached into bit-fields.
  
  dict_foreign_struct: Turn n_fields and type into bit-fields.
  
  rw_lock_t: Turn cline, last_s_line, and last_x_line into bit-fields.
  Omit level unless #defined UNIV_SYNC_DEBUG.
  
  Move REC_MAX_N_FIELDS (and REC_MAX_HEAP_NO and REC_MAX_N_OWNED)
  from rem0rec.c to rem0types.h, as they are needed in dict0dict.ic.
  dict_col_get_clust_pos(): Map REC_MAX_N_FIELDS to ULINT_UNDEFINED.
  
  
  Revision r816:
  Remove more remnants of mixed indexes.
  
  Revision r818:
  Remove dict_col_t::hash, dict_col_t::table,
  dict_sys->col_hash, and DICT_POOL_PER_COL_HASH.  (Bug #20877)
  
  The col->table pointer was only needed for maintaining a hash table of
  all defined columns in all tables.  The hash table was only looked up
  in dict_index_find_cols().  Removing the col->hash and col->table
  pointers reduces the size of a table column by two machine words
  (usually 8 or 16 bytes).
  
  dict_col_add_to_cache(), dict_col_reposition_in_cache(),
  dict_col_remove_from_cache(): Remove.  These only updated dict_sys->col_hash.
  
  dict_index_find_cols(): Use a linear search instead of the hash table.
  The time complexity is affected, but this function is only invoked by
  dict_index_add_to_cache(), and we only search the columns of a single
  table (typically at most a few dozen) as opposed to all columns of all
  tables.
  
  
  Revision r819:
  dict_col_t: Reduce ord_part to one bit.
  
  dict_index_add_to_cache(): Instead of incrementing ord_part, set it.
  
  dict_index_remove_from_cache(): Do not touch ord_part.
  
  dtype_t: Reduce mbminlen from 3 to 2 bits.
  
  row_upd(): Add a UNIV_LIKELY hint around node->in_mysql_interface.
  
  
  Revision r820:
  Remove dict_col_t::clust_pos.
  
  dict_col_get_clust_pos(): Add parameter clust_index.  Replace the
  look-up with a linear search of all columns in the clustered index.
  
  row_upd_index_replace_new_col_vals(): Compute clust_index outside
  the loops.  Compute clust_pos outside the inner loop.
  
  row_upd_changes_ord_field_binary(), row_upd_changes_first_fields_binary():
  Compute clust_index outside the loops.  Declare the auxiliary variables
  inside the loop scope.
  
  
  Revision r821:
  dict_table_t: Rename the integer field max_row_size
  to the Boolean field big_rows.  (Bug #20877)
  
  BIG_ROW_SIZE: Move the definition from row0sel.c to dict_table_add_to_cache().
  
  
  Revision r826:
  The code base was reindented in r763 and automatic .emacs indentation
  settings introduced. Some problems were found, so from this commit on one
  additional indentation rule is introduced:
  
   (add-to-list 'c-offsets-alist '(arglist-intro . +))
  
  Note that fixing some of the unfortunate line-splits done in r764 will be
  done in a future change.
  
  Revision r827:
  Make dict_index_find_cols() always succeed.
  
  Revision r828:
  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256
  bytes on 64-bit systems).  (Bug #20877)
  
  struct dict_tree_struct, dict_tree_t: Remove.
  
  struct dict_index_struct: Add page and lock.
  
  dict_tree_create(): Remove.  Replace the invocation with
  assignment to index->page and a call to rw_lock_create(&index->lock).
  
  dict_tree_free(): Remove.  Replace the invocation wtih
  a call to rw_lock_free(&index->lock).
  
  dict_index_get_tree(): Remove.
  
  dict_tree_get_space_reserve(): Rename to dict_index_get_space_reserve()
  and remove the parameter, which was unused.
  
  btr_level_list_remove(): Remove the unused parameter "tree".
  
  Replace the occurrences of "tree" with "index" in names of variables,
  functions and data types, e.g. "dict_tree_t tree" becomes
  "dict_index_t index".  Remove local variables "tree" or "index" of
  functions that needed both "tree" and "index".

  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should

  Remove dict_col_t::hash, dict_col_t::table,

  The col->table pointer was only needed for maintaining a hash table of
  all defined columns in all tables.  The hash table was only looked up
  in dict_index_find_cols().  Removing the col->hash and col->table
  pointers reduces the size of a table column by two machine words
  (usually 8 or 16 bytes).
  
  dict_col_add_to_cache(), dict_col_reposition_in_cache(),

  dict_index_find_cols(): Use a linear search instead of the hash table.
  The time complexity is affected, but this function is only invoked by
  dict_index_add_to_cache(), and we only search the columns of a single

  tables.

  Revision r818:
  Remove dict_col_t::hash, dict_col_t::table,
  dict_sys->col_hash, and DICT_POOL_PER_COL_HASH.  (Bug #20877)
  
  The col->table pointer was only needed for maintaining a hash table of
  all defined columns in all tables.  The hash table was only looked up
  in dict_index_find_cols().  Removing the col->hash and col->table
  pointers reduces the size of a table column by two machine words
  (usually 8 or 16 bytes).
  
  dict_col_add_to_cache(), dict_col_reposition_in_cache(),
  dict_col_remove_from_cache(): Remove.  These only updated dict_sys->col_hash.
  
  dict_index_find_cols(): Use a linear search instead of the hash table.
  The time complexity is affected, but this function is only invoked by
  dict_index_add_to_cache(), and we only search the columns of a single
  table (typically at most a few dozen) as opposed to all columns of all
  tables.

  Revision r833:
  Tweak the bit-field definitions introduced since r813 to address Bug #20877.
  
  rw_lock_t: Do not make writer_is_wait_ex a bit-field.  There are no fields
  yet that could be fused to the same machine word, but we play it safe,
  because the field writer_is_wait_ex may be modified by several threads
  simultaneously.  Such fields should always be allocated an own machine
  word.
  
  dict_table_t: Change the type of all bit-fields to "unsigned".  Make
  "space" a bit-field of 32 bits.  Move name_hash and id_hash after all
  bit-fields, so that the bit-fields can be allocated together.  Do not
  make autoinc_inited a bit-field, as we cannot allocate any field
  from the same machine word.
  
  dict_build_table_def_step(): Pass a local variable to
  fil_create_new_single_table_tablespace() and initialize table->space
  from it after the call, now that table->space is a bit-field.

  Revision r833:
  Tweak the bit-field definitions introduced since r813 to address Bug #20877.
  
  rw_lock_t: Do not make writer_is_wait_ex a bit-field.  There are no fields
  yet that could be fused to the same machine word, but we play it safe,
  because the field writer_is_wait_ex may be modified by several threads
  simultaneously.  Such fields should always be allocated an own machine
  word.
  
  dict_table_t: Change the type of all bit-fields to "unsigned".  Make
  "space" a bit-field of 32 bits.  Move name_hash and id_hash after all
  bit-fields, so that the bit-fields can be allocated together.  Do not
  make autoinc_inited a bit-field, as we cannot allocate any field
  from the same machine word.
  
  dict_build_table_def_step(): Pass a local variable to
  fil_create_new_single_table_tablespace() and initialize table->space

  Remove dict_tree_t, which should have been removed in r453.

  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256

  Revision r832:
  Add dict_table_get_col_name() in preparation for getting rid of
  dict_col_t::name, and use it instead of col->name everywhere.
  
  Revision r834:
  dict_col_t: Copy the fields of "dtype_t type" directly to this structure,
  so that all integer fields can be packed into 64 bits.  (Bug #20877)
  
  dtype_t: Change the type of all bit-fields to unsigned.
  
  dict_table_get_nth_col(), dict_table_get_sys_col_noninline(),
  dict_table_get_sys_col(), dict_field_get_col(): Return const
  dict_col_t*, so that changes to dict_col_t can be detected more
  easily.  Add const to many dict_col_t* declarations.
  
  dict_index_get_nth_type(): Replace with dict_index_get_nth_col().
  
  dict_col_get_type(): Replace with dict_col_copy_type().
  
  dict_col_get_min_size(), dict_col_get_max_size(), dict_col_get_fixed_size(),
  dict_col_get_sql_null_size(): New functions.
  
  dtype_get_at_most_n_mbchars(): Replace the parameter dtype
  with the parameters prtype, mbminlen, mbmaxlen.
  
  dtype_get_pad_char(), cmp_data_data(), cmp_data_data_slow(),
