7a1f31866c MDEV-4946: IO thread should expose its current GTID position 
Add another column to SHOW SLAVE STATUS, and adjust test suite
to cope.

1cd6eb5f94 MDEV-26: Global transaction ID. 
Change of user interface to be more logical and more in line with expectations
to work similar to old-style replication.

User can now explicitly choose in CHANGE MASTER whether binlog position is
taken into account (master_gtid_pos=current_pos) or not (master_gtid_pos=
slave_pos) when slave connects to master.

@@gtid_pos is replaced by three separate variables @@gtid_slave_pos (can
be set by user, replicated GTIDs only), @@gtid_binlog_pos (read only), and
@@gtid_current_pos (a combination of the two, most recent GTID within each
domain). mysql.rpl_slave_state is renamed to mysql.gtid_slave_pos to match.

This fixes MDEV-4474.

d9f975d08b MDEV-26: Global transaction ID 
Adjust full test suite to work with GTID.

Huge patch, mainly due to having to update .result file for all SHOW BINLOG
EVENTS and mysqlbinlog outputs, where the new GTID events pop up.

Everything was painstakingly checked to be still correct and valid .result
file updates.

5eccc400b1 Implementation of Multi-source replication (MDEV:253) 
Documentation of the feature can be found at: http://kb.askmonty.org/en/multi-source-replication/
This code is based on code from Taobao, developed by Plinux

Other things:
- Added new commands: START ALL SLAVES, STOP ALL SLAVES and SHOW FULL SLAVE STATUS
- Almost all usage of 'active_mi' is deleted.
- Added parameter to reset_logs() so that one can specify if new logs should be created.
- Check wildcard match as early as possible for SHOW STATUS. This makes SHOW STATUS like 'xxx' a lot faster and use less mutex
- Made max_relay_log_size depending on master connection.
- Added sys_vars.default_master_connection_basic to fix a failure in sys_vars.all_vars, modified sql_slave_skip_counter_basic to allow session-level settings
- Added commands to mysqladmin: start-all-slaves & stop-all-slaves
- Removed logging of "next log '%s' is currently active | not active"
- Fixed bug in my_vsnprintf() when using positional parameters with length
- Added fn_ext2(), which returns pointer to last '.' in file name
- max_relay_log_size now acts as a normal slave specific variable
- Don't store replication position if innobase_overwrite_relay_log_info is not set
- max_relay_log_size copies it's values from max_binlog_size at startup
