Let expand_symtabs_matching short-circuit

This changes expand_symtabs_exp_notify_ftype to return bool, and
updates all the uses.  Now, if the notification function returns
false, the call is short-circuited and stops examining symtabs.  This
is a step toward replacing map_symtabs_matching_filename with
expand_symtabs_matching.
