*	MDEV-13073 This part merges the Ali semisync related changes	Andrei Elkin	2017-12-18	1	-20/+30
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	and specifically the ack receiving functionality. Semisync is turned to be static instead of plugin so its functions are invoked at the same points as RUN_HOOKS. The RUN_HOOKS and the observer interface remain to be removed by later patch. Todo: React on killed status by repl_semisync_master.wait_after_sync(). Currently Repl_semi_sync_master::commit_trx does not check the killed status. There were few bugfixes found that are present in mysql and its unclear whether/how they are covered. Those include: Bug#15985893: GTID SKIPPED EVENTS ON MASTER CAUSE SEMI SYNC TIME-OUTS Bug#17932935 CALLING IS_SEMI_SYNC_SLAVE() IN EACH FUNCTION CALL HAS BAD PERFORMANCE Bug#20574628: SEMI-SYNC REPLICATION PERFORMANCE DEGRADES WITH A HIGH NUMBER OF THREADS
*	Optimize RUN_HOOK() call	Monty	2017-12-18	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \|	RUN_HOOK() is only called if semisync is enabled As the server can't disable the hooks if something is in progress, I added a new variable, run_hooks_enabled, that is set the first time semi sync is used. This means that RUN_HOOK will have no overhead, unless semi sync master or slave has been enabled once. Some of the changes was just to get rid of warnings for embedded server
*	Moved semisync from a plugin to normal server	Monty	2017-12-18	1	-0/+101
	Part of MDEV-13073 AliSQL Optimize performance of semisync Did the following renames to match other similar variables key_ss_mutex_LOCK_binlog_ > key_LOCK_bing key_ss_cond_COND_binlog_send_ -> key_COND_binlog_send COND_binlog_send_ -> COND_binlog_send LOCK_binlog_ -> LOCK_binlog debian/mariadb-server-10.2.install does not install semisync libs.
