INSTALL SONAME ignores attempts to load the same plugin twice, it's not an error
(because one can load one plugin by name and then install soname for the rest).
But Federated and FederatedX are different plugins, despite having the same name.
Now plugin_add() only considers two plugins identical if their names are the same
string (compared as pointers). Otherwise it reports an error.,
rpl.rpl_gtid_crash fail on PPC64
This is an addition to the original patch.
Restored show binlog events output and adjusted filters to
replace [\d-\d-\d,\d-\d-\d,\d-\d-\d] with [#-#-#].
Remove the "don't update the row for b'' and store uninitialized bytes on disk" change.
Update test cases to allow DEFAULT b'', because b'' is a valid expression elsewhere.
when looking for my.cnf files: if DEFAULT_SYSCONFDIR (or INSTALL_SYSCONFDIR)
is specified (for rpms it always is), use that instead of hardcoded /etc path.

This is an addition to the original patch. On Windows
InterlockedExchange implies full memory barrier, whereas
only acquire/release barriers required.
buf0flu.cc line 549.
Analysis: If buf_page_get_state(bpage) == BUF_BLOCK_REMOVE_HASH then
buf_page_in_file(bpage) might not be true.
Fix: ut_a(buf_page_in_file(bpage) || buf_page_get_state(bpage) == BUF_BLOCK_REMOVE_HASH);
There was a race condition in lock_table_names() which didn't properly test for CREATE OR REPLACE for slaves.

Copy create_info flags to thd for lock_table_names()

Copy create_info flags to thd for lock_table_names()
main.mysqlslap fail on PPC64
There seem to be a bug on Power8 which doesn't guarantee
a signal to be delivered to waiting thread if broadcast
is called outside of mutex.
For now workaround it by calling broadcast while mutex is
still held.
4229: MDEV-5670: Assertion failure in file buf0lru.c line 2355
Add more status information if repeatable.
4230: MDEV-5673: Crash while parallel dropping multiple tables under heavy load
Improve long semaphore wait output to include all semaphore waits
and try to find out if there is a sequence of waiters.
4233: Fix compiler errors on product build.
4237: Fix too agressive long semaphore wait output and add guard against introducing
compression failures on insert buffer.
4238: Fix test failure caused by simulated compression failure on
IBUF_DUMMY table.
This problem affects only debug builds on PPC64.
There are at least two race conditions around
rw_lock_debug_mutex_enter and rw_lock_debug_mutex_exit:
- rw_lock_debug_waiters was loaded/stored without setting
appropriate locks/memory barriers.
- there is a gap between calls to os_event_reset() and
os_event_wait() and in such case we're supposed to pass
return value of the former to the latter.
Fixed by replacing self-cooked spinlocks with system mutexes.
These days system mutexes offer much better performance. OTOH
performance is not that critical for debug builds.
mysql.column_stats wasn't stored/restored properly on big-endian
with histogram_type=DOUBLE_PREC_HB.
Store histogram values using int2store()/uint2korr().
Note that this patch invalidates previously calculated histogram
values on big-endian.
If mysql.innodb_table_stats or mysql.innodb_index_stats is not found or has
unexpected structure output that error only once and no other error for
every table trying to use them. If they do exists, then print fetch or
recalculation errors only once / table or index.

In case InnoDB index is not found, print the MySQL and InnoDB index
name we were trying to find and all MySQL and InnoDB index names there
is for this table.
ha_innodb.cc line 8473
If index is not found from InnoDB make sure we print what we
were trying to find and all mysql and InnoDB index names there
is for this table.
