MDEV-5914: Parallel replication deadlock due to InnoDB lock conflicts
Preparation patch for investigating a possible solution.
Add THD::rpl_
group_commit_ id. This will be zero except when running
multiple transactions in parallel in parallel replication. Then it
can be compared between two THDs to check if these are two
transactions that were group-committed together on the master and
thus are known not to conflict. - 4071. By Sergey Vojtovich

MDEV-5864 - Reduce usage of LOCK_open: TABLE_SHARE:
:tdc.free_ tables Let TABLE_SHARE:
:tdc.free_ tables, TABLE_SHARE: :tdc.all_ tables,
TABLE_SHARE::tdc.flushed and corresponding invariants be protected by
per-share TABLE_SHARE::tdc.LOCK_ table_share instead of global LOCK_open. - 4066. By Sergey Petrunia

MDEV-5901: EITS: killing the server leaves statistical tables in "marked as crashed" state
- Part#2: call HA_EXTRA_FLUSH for the correct handler object, and call it after every change
(ha_write_row, ha_update_row, ha_delete_row).
