Check whether the master and purge thread are active after creating them. Do
not proceed until both threads have started. We do this by checking whether a
slot has been reserved by both the respective threads.
      
Add srv_thread_has_reserved_slot() returns slot no or ULINT_UNDEFINED.

This is 5.1 built-in specific as the dict_table_t strcture is allocated
with mem_heap_zalloc since 5.1 plugin.

Avoid handler::info() call for three Information Schema tables;
TABLE_CONSTRAINTS, KEY_COLUMN_USAGE, & REFERENTIAL_CONTRAINTS

This adds 64 new rows to performance_schema.rwlock_instances.

This patch will make perfschema.binlog_mix perfschema.binlog_row tests fail,
but they will be fixed by http://lists.mysql.com/commits/127862

ASSERT happens due to improper calculation of the max_length
in Item_func_div object, if dividend has max_length == 0 then
Item_func_div::max_length is set to 0 under some circumstances.
The fix:
If decimals == NOT_FIXED_DEC then set
Item_func_div::max_length to max possible
DOUBLE length value.

BUG #59055: RQG was broken after the checkin that removed rpl and rpl_ndb suites. RQG uses MTR V1 and that still has these in the default suite. Removing these from V1. Also removing references to ndb tests in some more disabled.def files

Problem: master executed a statement that would fail on slave
(namely, DROP USER 'create_rout_db'@'localhost').
Then the test did:
  --let $rpl_only_running_threads= 1
  --source include/rpl_reset.inc
rpl_reset.inc calls rpl_sync.inc, which first checks which of
the threads are running and then syncs those threads that are
running. If the SQL thread fails after the check, the sync will
fail. So there was a race in the test and it failed on some
slow hosts.
Fix: Don't replicate the failing statement.

Item_sum_max/Item_sum_min incorrectly set null_value flag and
attempt to get result in parent functions leads to crash.
This happens due to double evaluation of the function argumet.
First evaluation happens in the comparator and second one
happens in Item_cache::cache_value().
The fix is to introduce new Item_cache object which
holds result of the argument and use this cached value
as an argument of the comparator.

This bug fix requires that Bug #58912 be fixed as well (bzr revision id
marko.makela@oracle.com-20101221093919-mcmmgd4zpse9567d). Otherwise,
another double BLOB free could occur when InnoDB would try to perform
an update-in-place as delete-and-insert-by-update-in-place.

row_upd_clust_rec_by_insert(): Do not disown the externally stored
columns from the old record (btr_cur_mark_extern_inherited_fields())
until after checking the foreign key constraints and successfully
inserting the updated record. If a lock wait timeout occurs between
the delete-marking of the old record and the insertion of the updated
record, mark the columns inherited before retrying the insert.
Distinguish the state UPD_NODE_INSERT_BLOB from
UPD_NODE_INSERT_CLUSTERED.

btr_cur_del_mark_set_clust_rec(): Replace the cursor with
block,rec,index,offsets so that the offsets need not be recalculated.
Assert that rec is on a clustered index leaf page.

btr_cur_disown_inherited_fields(): Renamed from
btr_cur_mark_extern_inherited_fields(). Use
upd_get_field_by_field_no(). Assert that there are externally stored
columns. Assert that a mini-transaction is passed. Remove the return
status. (The only caller, row_upd_clust_rec_by_insert(), will have
determined that some fields have changed ownership.)

btr_cur_mark_dtuple_inherited_extern(): Rename to
row_upd_clust_rec_by_insert_inherit_func() and declare as static. Add
the debug parameters rec, offsets. When rec is given, assert that the
off-page columns match those in the inesrt tuple and that the off-page
columns are owned by the record. Assert that the non-updated off-page
columns in the insert tuple are owned, and mark them inherited.

row_upd_clust_rec_by_insert_inherit(): A wrapper macro for
row_upd_clust_rec_by_insert_inherit_func().

row_undo_mod_upd_exist_sec(): Adjust a comment about
row_upd_clust_rec_by_insert().

Normally, auto_increment value is generated for the column by
inserting either NULL or 0 into it. NO_AUTO_VALUE_ON_ZERO
suppresses this behavior for 0 so that only NULL generates
the auto_increment value. This behavior is also followed by
a slave, specifically by the SQL Thread, when applying events
in the statement format from a master. However, when applying
events in the row format, the flag was ignored thus causing
an assertion failure:
"Assertion failed: next_insert_id == 0, file .\handler.cc"
      
In fact, we never need to generate a auto_increment value for
the column when applying events in row format on slave. So we
don't allow it to happen by using 'MODE_NO_AUTO_VALUE_ON_ZERO'.
      
Refactoring: Get rid of all the sql_mode checks to rows_log_event
when applying it for avoiding problems caused by the inconsistency
of the sql_mode on slave and master as the sql_mode is not set for
Rows_log_event.

row_upd_changes_ord_field_binary(): Do not return TRUE if the update
vector changes a column that is covered by a prefix index, but does
not change the column prefix. Add the row_ext_t parameter for
determining whether the prefixes of externally stored columns match.

dfield_datas_are_binary_equal(): Add the parameter len, for comparing
column prefixes when len > 0.

innodb.test: Add a test case where the patch of Bug #55284 failed
without this fix.
