    style: rename some functions for consistency
    
    "handle_" is the prefix used in scan-code.l for instance.
    
    * src/parse-gram.y (do_error_verbose, do_name_prefix, do_require)
    (do_skeleton, do_yacc):
    Rename as...
    (handle_error_verbose, handle_name_prefix, handle_require)
    (handle_skeleton, handle_yacc):
    these.
