Fix for

BUG#797 "If query ignored on slave (replicate-ignore-table) the slave still checks if
the returned error (0) is the same as the one on the master, whereas it shouldn't
test this.
Plus a new test for BUG#797.


include/mysqld_error.h:
  New error code (can be sent only to the slave thread, not to normal clients).
sql/log.cc:
  removed comment from a previous debugging.
sql/log_event.cc:
  ER_SLAVE_IGNORED_TABLE is an ignorable error.

sql/sql_parse.cc:
  when in sql_parse in the slave thread we ignore the query because of replicate-do
  and replicate-ignore options, we return a specific error to the slave thread,
  so that it knows that the query has been ignored (which is different from a
  successful query).
  A small cleanup (test was done twice).
