Bug#14575

  ¨MySQL server crashes if you try to access to InnoDB table¨
  crash caused by schizophrenic mysqld - 2 memory locations for logically same function
  with conflicting values.
  Fixed by backporting from 5.1 changes to have_xyz_db declarations.


sql/mysql_priv.h:
  Backport have_xyz_db changes from 5.1
sql/mysqld.cc:
  Backport have_xyz_db changes from 5.1
