for InnoDB plugin

dict_load_table(): Pass the correct tablespace flags to
fil_open_single_table_tablespace(). For ROW_FORMAT=COMPACT and REDUNDANT,
the tablespace flags are 0. The table flags would be 0 or DICT_TF_COMPACT.

introduced in bug fix #53592, since dict_table_t can sufficiently unique
identify the the table.

In semi-consistent read, only unlock freshly locked non-matching records.

lock_rec_lock_fast(): Return LOCK_REC_SUCCESS,
LOCK_REC_SUCCESS_CREATED, or LOCK_REC_FAIL instead of TRUE/FALSE.

enum db_err: Add DB_SUCCESS_LOCKED_REC for indicating a successful
operation where a record lock was created.

lock_sec_rec_read_check_and_lock(),
lock_clust_rec_read_check_and_lock(), lock_rec_enqueue_waiting(),
lock_rec_lock_slow(), lock_rec_lock(), row_ins_set_shared_rec_lock(),
row_ins_set_exclusive_rec_lock(), sel_set_rec_lock(),
row_sel_get_clust_rec_for_mysql(): Return DB_SUCCESS_LOCKED_REC if a
new record lock was created. Adjust callers.

row_unlock_for_mysql(): Correct the function documentation.

row_prebuilt_t::new_rec_locks: Correct the documentation.

In semi-consistent read, only unlock freshly locked non-matching records.

Define DB_SUCCESS_LOCKED_REC for indicating a successful operation
where a record lock was created.

lock_rec_lock_fast(): Return LOCK_REC_SUCCESS,
LOCK_REC_SUCCESS_CREATED, or LOCK_REC_FAIL instead of TRUE/FALSE.

lock_sec_rec_read_check_and_lock(),
lock_clust_rec_read_check_and_lock(), lock_rec_enqueue_waiting(),
lock_rec_lock_slow(), lock_rec_lock(), row_ins_set_shared_rec_lock(),
row_ins_set_exclusive_rec_lock(), sel_set_rec_lock(),
row_sel_get_clust_rec_for_mysql(): Return DB_SUCCESS_LOCKED_REC if a
new record lock was created. Adjust callers.

row_unlock_for_mysql(): Correct the function documentation.

row_prebuilt_t::new_rec_locks: Correct the documentation.

rw_lock_t: Remove magic_n unless UNIV_DEBUG is defined.
rw_lock_free(): Invalidate magic_n only after removing from rw_lock_list.

lock_rec_unlock(): Cache first_lock and rewrite while() loops as for().

btr_cur_optimistic_update(): Use common error handling return.

row_create_prebuilt(): Add Valgrind instrumentation.

row_undo_mod_upd_exist_sec(): Tolerate a failure to build the index entry
for a DYNAMIC or COMPRESSED table during crash recovery.

    Fix Bug #53947 InnoDB: Assertion failure in thread 4224 in file .\sync\sync0sync.c line 324
    
    Destroy the rw-lock object before freeing the memory it is occupying.
    If we do not do this, then the mutex that is contained in the rw-lock
    object btr_search_latch_temp->mutex gets "freed" and subsequently
    mutex_free() from sync_close() hits a mutex whose memory has been
    freed and crashes.

    Discussed with:	Calvin

err_index could be not a member of the share structure or prebuilt
structure passed from MySQL. For now, we resort to the traditional
way of scanning index->table for the index number.

list a thread doing a wait_ex as an s-lock waiter.

after fast alter table added unique key". Look up MySQL index number should
go through index translation table.

from mysql-trunk-innodb

Store the max_space_id in the data dictionary header in order to avoid
space_id reuse.

DICT_HDR_MIX_ID: Renamed to DICT_HDR_MAX_SPACE_ID, DICT_HDR_MIX_ID_LOW.

dict_hdr_get_new_id(): Return table_id, index_id, space_id or a subset of them.

fil_system_t: Add ibool space_id_reuse_warned.

fil_create_new_single_table_tablespace(): Get the space_id from the caller.

fil_space_create(): Issue a warning if the fil_system->max_assigned_id
is exceeded.

fil_assign_new_space_id(): Return TRUE/FALSE and take a pointer to the
space_id as a parameter. Make the function public.

fil_init(): Initialize all fil_system fields by mem_zalloc(). Remove
explicit initializations of certain fields to 0 or NULL.

BUILD/*: Add valgrind_configs=--with-valgrind.
BUILD/*: Remove -USAFEMALLOC from valgrind_flags.

configure.in: Add AC_ARG_WITH(valgrind) and HAVE_VALGRIND.

include/my_sys.h: Define a number of MEM_ wrappers for VALGRIND_ functions.
include/my_sys.h: Make TRASH do MEM_UNDEFINED().

include/m_string.h: Remove unused macro bzero_if_purify(A,B).

_mymalloc(): Declare MEM_UNDEFINED() on the allocated memory.

_myfree(): Declare MEM_NOACCESS() on the freed memory.

storage/innobase/include/univ.i: Enable UNIV_DEBUG_VALGRIND based on
HAVE_VALGRIND rather than HAVE_purify.

Possible things to do:
 * In my_global.h, remove the defined(HAVE_purify) condition
   from the _WIN32 uint3korr().
 * In my_global.h *int*korr(), use | instead of +
   in order to keep the Valgrind V bits accurate
 * Consider replacing HAVE_purify with HAVE_VALGRIND
 * Use VALGRIND_CREATE_BLOCK, VALGRIND_DISCARD in mem_root and similar places

This merge is non-trivial since it has to introduce the DB_INTERRUPTED
error code.

Also revert vasil.dimov@oracle.com-20100408165555-9rpjh24o0sa9ad5y
which adjusted the binlog.binlog_killed test to the new (wrong) behavior

Use | instead of +, and mask out the dont-care bits in debug assertions.
