Fix error message generated when trying to create a table in a

non-existent database. (Bug #10407)


mysql-test/r/create.result:
  Update results
mysql-test/t/create.test:
  Update error numbers
sql/mysql_priv.h:
  Adjust some other function signature so table and db information
  is passed down into create_frm().
sql/sql_table.cc:
  Check for database not existing after hitting an error when
  copying the .frm file for 'CREATE TABLE ... LIKE ...', and
  pass table and db name into rea_create_table().
sql/table.cc:
  Generate specific error message when .frm creation fails because
  the database does not exist.
sql/unireg.cc:
  Pass database and table name down into create_frm().
