In-order commit for Taobao parallel replication.

Fix deadlock with MyISAM tables. If T2 got a table lock before T1,
then T1 would wait for T2 to complete, and T2 would wait for T1 to
commit -> deadlock.

Now, for non-transactional tables, we consider it a conflict when
*any* update happens to the same table (regardless of key values).
Most such updates to MyISAM cannot be done in parallel anyway due
to table-level locking.

(Later we might want to introduce a special flag for this for
storage engines, as even transactional engines could have
page-level locking or lock escalation or similar with similar
deadlock issues).

MBug#702303: Spurious `use` statements in output from mysqlbinlog --rewrite-db="a->b"

Merge Percona patch row_based_replication_without_primary_key.patch into MariaDB.

This patch improves the selection of index to use to apply row-based
DELETE and UPDATE events on tables with no primary key (original code
picks the first index unconditionally).
If ANALYZE TABLE is done, the index cardinalities will be compared and
the best index will be used.

Fixes some problems in the original patch:

 - Without ANALYZE TABLE, rec_per_key statistics is not available; in this
   case the original patch could choose a really bad index, even ignoring
   a primary key.

 - The original patch did not consider multi-column keys correctly, and
   could thus pick a less desirable single-column key over a good
   multi-column index.

Also fixes Bug#58997, and adds test cases.
