Review of new code:

Change argument order to be database, tablename for some functions


sql/lock.cc:
  Remove not needed block
sql/mysql_priv.h:
  Change argument order to be database, tablename (like in most other functions)
sql/sql_table.cc:
  Change argument order to be database, tablename (like in most other functions)
  Make 'flags' inline
sql/table.cc:
  Change argument order to be database, tablename (like in most other functions)
sql/unireg.cc:
  Change argument order to be database, tablename (like in most other functions)
