Various changes to get libmysqld in sync with latest sources.

BitKeeper/etc/ignore:
  Added libmysqld/uniques.cc
client/mysqltest.c:
  Don't core dump if --socket isn't specified.
  
  Add --test-file option, to facilitate running mysqltest under debugger.
libmysqld/Makefile.am:
  We need uniques.cc
libmysqld/lib_sql.cc:
  Tiny cleanup.
libmysqld/libmysqld.c:
  Split mysql_real_query() into mysql_send_query() and
  mysql_read_query_results().
