  trx_sys_file_format_max_upgrade(): Rename from
  trx_sys_file_format_max_update().  Improve the documentation.  Add a
  const qualifier to the parameter "name".  Replace the parameter
  "flags" with "format_id", because this function should deal with file
  format identifiers, not with table flags.

  trx_sys_file_format_max_write(), trx_sys_file_format_max_set(): Add a
  const qualifier to the parameter "name".

  ha_innodb.cc: Correct the spelling in some comments: "side effect".
  Remove redundant prototypes for some static callback functions.

  innodb_file_format_name_update(), innodb_file_format_check_update():
  Correct the function signature.  Use appropriate pointer type conversions.

  MYSQL_SYSVAR_STR(file_format), MYSQL_SYSVAR_STR(file_format_check):
  Remove the type conversions from the callback function pointers.  When
  the function signatures match, no type conversion is needed.  The type
  conversions would only prevent compilation warnings for any mismatch.

  branches/zip: Skip the undo log size check on REDUNDANT and COMPACT tables.

  In ROW_FORMAT=DYNAMIC and ROW_FORMAT=COMPRESSED, column prefix indexes
  require that prefixes of externally stored columns be written to the
  undo log. This may make the undo log record bigger than the record on
  the B-tree page.  The maximum size of an undo log record is the page
  size.  That must be checked for, in dict_index_add_to_cache().

  dict_index_add_to_cache(): Skip the undo log size check for REDUNDANT
  and COMPACT tables. These tables store prefixes of externally stored
  columns locally within the clustered index record.  There are no special
  considerations for the undo log record size.

  innodb-index.test: Ensure that the check exists for ROW_FORMAT=DYNAMIC,
  but not for ROW_FORMAT=COMPACT.

  branches/zip: When the server crashes while freeing an externally stored
  column of a compressed table, the BTR_EXTERN_LEN field in the BLOB pointer
  will be written as 0.  Tolerate this in the functions that deal with
  externally stored columns.  This fixes Issue #80 and was posted at rb://26.

  Note that the clustered index record is always deleted or purged last,
  after any secondary index records referring to it have been deleted.

  btr_free_externally_stored_field(): On an uncompressed table, zero out
  the BTR_EXTERN_LEN, so that half-deleted BLOBs can be detected after
  crash recovery.

  btr_copy_externally_stored_field_prefix(): Return 0 if the BLOB has been
  half-deleted.

  row_ext_cache_fill(): Allow btr_copy_externally_stored_field_prefix()
  to return 0.

  row_sel_sec_rec_is_for_blob(): Return FALSE if the BLOB has been half-deleted.
  This is correct, because the clustered index record would have been deleted
  or purged last, after any secondary index records referring to it had been
  deleted.

ibuf_get_entry_counter_low(): Rename from ibuf_set_entry_counter_low().

This seems to hold also for all calls from the insert buffer.

buf_page_optimistic_get_func(): Do not pass mtr to ibuf_page(), because
there is no guarantee that mtr would contain an x-latch to the insert
buffer bitmap page that covers (block->page.space, block->page.offset).

zip_size should always equal fil_space_get_zip_size(space), even when called
from ibuf.

ibuf_page() should be called with mtr=NULL to be equivalent to the original
implementation.  We cannot assume that mtr holds an x-latch on the insert
buffer bitmap page that covers the page that is being requested.
