Post-merge fixes.

mysql-test/r/federated.result:
  A post-merge fix.
mysql-test/r/show_check.result:
  A post-merge fix.
sql/log_event.cc:
  Remove rewrite_db (it's refactored in 5.1 to rpl_filter)
sql/share/errmsg.txt:
  Move ER_NO_TRIGGERS_ON_SYSTEM_SCHEMA to the end of the list.
  This breaks compatibility of errmsg.sys with 5.0 but preserves 
  compatibility with 5.1.11.
sql/sql_class.h:
  A post-merge fix.
