DUPLICATE KEY UPDATE.
We should assume that the store engine will report the first duplicate key for this case.
Old code of suppression of unsafe logging error with LIMIT didn't work, because of wrong usage of my_interval_timer().
Suppress unsafe logging errors to the error log if we get too many unsafe logging errors in a short time.
This is to not overflow the error log with meaningless errors.
- Each error code is suppressed and counted separately.
- We do a 5 minute suppression of new errors if we get more than 10 errors in that time.
Only print unsafe logging errors if log_warnings > 1.

Various backslash escapes and quote-quote escaped sequences are covered
in combination with single and multi-byte characters.
This is especially important for the character sets that can have 0x5C
as the second byte in a multi-byte character (big5, cp932, gbk, sjis).
swe7 is also a special character set, because in swe7 0x5C is used for
both escape character and for "LATIN CAPITAL LETTER O WITH DIAERESIS".

filesort.
The problem was that my_hash_sort didn't properly delete end-space characters properly, so strings that should compare
identically was seen as different strings. (Space was handled correctly, but not NBSP)
This caused duplicate key errors when a heap table was converted to Aria as part of overflow in group by.
Fixed by removing all characters that compares as end space when creating a hash.
Other things:
- Fixed that --sorted_results also works for errors in mysqltest.
- Speed up hash by not comparing strings that has different hash.
- Speed up many my_hash_sort functions by using registers to calculate hash instead of pointers.
This was previously done for some functions, but not for all.
- Made a macro of the hash function, to simplify code and to be able to experiment with new hash functions.

CREATE IF NOT EXISTS ... SELECT was returning an error status to the caller,

and trusted that error status means an error.

The Item_string constructors called set_name() on the source string,
which was wrong because in case of UCS2/UTF16/UTF32 the source value
might be a not well formed string (e.g. have incomplete leftmost character).
Now set_name() is called on str_value after its copied
(with optionally left zero padding) from the source string.

code between Item_string and Item_param.

master crashes in the middle of transaction
If the slave gets a reconnect in the middle of a GTID event group, normally
it will re-fetch that event group, skipping the first part that was already
queued for the SQL thread.
However, if the master crashed while writing the event group, the group is
incomplete. This patch detects this case and makes sure that the
transaction is rolled back and nothing is skipped from any following
event groups.
Similarly, a network proxy might cause the reconnect to end up on a
different master server. Detect this by noticing a different server_id,
and similarly in this case roll back the partially received group.

serialised correctly
Follow-up patch, fixing a possible deadlock issue.
If the master crashes in the middle of an event group, there can be an active
transaction in a worker thread when we encounter the following master restart
format description event. In this case, we need to notify that worker thread
to abort and roll back the partial event group. Otherwise a deadlock occurs:
the worker thread waits for the commit that never arrives, and the SQL driver
thread waits for the worker thread to complete its event group, which it never
does.

serialised correctly
When a master server starts up, it logs a special format_description event at
the start of a new binlog to mark that is has restarted. This is used by a
slave to drop all temporary tables - this is needed in case the master crashed
and did not have a chance to send explicit DROP TEMPORARY TABLE statements to
the slave.
In parallel replication, we need to be careful when dropping the temporary
tables - we need to be sure that no prior events are still executing that
might be using the temporary tables to be dropped, _and_ that no following
events have started executing that might have created new temporary tables
that should not be dropped.
This was not handled correctly, which could cause errors about access to not
existing temporary tables or even crashes. This patch implements that such
format_description events cause serialisation of event execution; all prior
events are executed to completion first, then the format_description event is
executed, dropping temporary tables, then following events are queued for
execution.
Master restarts should be sufficiently infrequent that the resulting loss of
parallelism should be of minimal impact.
