Merge lp:~akopytov/percona-xtrabackup/support-gtid-2.1 into lp:percona-xtrabackup/2.1

[Alexey Kopytov]

    Implementation of
    https://blueprints.launchpad.net/percona-xtrabackup/+spec/support-gtid

    Include the value of gtid_executed (or its Executed_Gtid_Set
    equivalent from SHOW MASTER STATUS) into xtrabackup_binlog_info. The
    value (when available) is also printed by innobackupex along with the
    binary log position, e.g.:

    "
    innobackupex: MySQL binlog position: filename 'mysql-bin.000003',
    position 1781, gtid_executed bf9000c0-acc2-11e2-a411-ae6a09f09722:1-3
    "
