Fixes the following bugs:
- Bug #33349: possible race condition revolving around data dictionary and repartitioning
Introduce retry/sleep logic as a workaround for a transient bug
where ::open fails for partitioned tables randomly if we are using
one file per table.
- Bug #34053: normal users can enable innodb_monitor logging
In CREATE TABLE and DROP TABLE check whether the table in question is one
of the magic innodb_monitor tables and whether the user has enough rights
to mess with it before doing anything else.
- Bug #22868: 'Thread thrashing' with > 50 concurrent conns under an upd-intensive workloadw
- Bug #29560: InnoDB >= 5.0.30 hangs on adaptive hash rw-lock 'waiting for an X-lock'
This is a combination of changes that forward port the scalability fix applied to 5.0
through r1001.
It reverts changes r149 and r122 (these were 5.1 specific changes made in lieu of
scalability fix of 5.0)
Then it applies r1001 to 5.0 which is the original scalability fix.
Finally it applies r2082 which fixes an issue with the original fix.
- Bug #30930: Add auxiliary function to retrieve THD::thread_id
Add thd_get_thread_id() function. Also make check_global_access() function
visible to InnoDB under INNODB_COMPATIBILITY_HOOKS #define.
The unsignedness of large integer user variables was not being
properly preserved when feeded to prepared statements. This was
happening because the unsigned flags wasn't being updated when
converting the user variable is converted to a parameter.
The solution is to copy the unsigned flag when converting the
user variable to a parameter and take the unsigned flag into
account when converting the integer to a string.
The problem is that one can not create a stored routine if sql_mode
contains NO_ENGINE_SUBSTITUTION or PAD_CHAR_TO_FULL_LENGTH. Also when
a event is created, the mode is silently lost if sql_mode contains one
of the aforementioned. This was happening because the table definitions
which stored sql_mode values weren't being updated to accept new values
of sql_mode.
The solution is to update, in a backwards compatible manner, the various
table definitions (columns) that store the sql_mode value to take into
account the new possible values. One incompatible change is that if a event
that is being created can't be stored to the mysql.event table, an error
will be raised.
The tests case also ensure that new SQL modes will be added to the mysql.proc
and mysql.event tables, otherwise the tests will fail.
The problem is that deprecated syntax warnings were not being
suppressed when the stored routine is being parsed for the first
execution. It's doesn't make sense to print out deprecated
syntax warnings when the routine is being executed because this
kind of warning only matters when the routine is being created.
The solution is to suppress deprecated syntax warnings when
parsing the stored routine for loading into the cache (might
mean that the routine is being executed for the first time).

Bug #34245 Test ndb_binlog_multi fails for 'CREATE TABLE'
Bug #34246 Test rpl_ndb_transaction fails with 'Failed to create
'mysql/ndb_apply_status'
Tests cases didn't wait for cluster to come up due to a typo
in have_multi_ndb.inc.
