Simplified quick_rm_table() and mysql_rename_table()

Browse Source 
Replaced obscure FRM_ONLY, NO_FRM_RENAME, NO_HA_TABLE, NO_PAR_TABLE with
straightforward explicit flags:

QRMT_FRM - [re]moves .frm
QRMT_PAR - [re]moves .par
QRMT_HANDLER - calls ha_delete_table()/ha_rename_table() and [re]moves
               high-level indexes
QRMT_DEFAULT - same as QRMT_FRM | QRMT_HANDLER, which is regular table
               drop/rename.
