Added SHOW MASTER LOGS as synonym for SHOW BINARY LOGS.

Added PURGE BINARY LOGS as synonym for PURGE MASTER LOGS.
Removed PURGE LOGS (now PURGE MASTER LOGS).
Added SHOW BDB LOGS as synonym for SHOW LOGS.
Note: tests key_cache.test hanged, rpl_log_pos.test, rpl_rotate_logs.test failed for me.
For the second and third one I guess this will disappear after merging 4.0.
