parser: always use stream-associated parser for parse_once.

This refactoring is needed for fixing the off-by-one
line number bug when the hash bang line is processed.

* eval.c (load): Don't define parser locally; ensure there is
one in the stream and use it.

* match.c (v_load): Likewise.

* parser.c (get_parser_impl): Renamed to parser_get_impl and
changed from internal to external linkage.
(ensure_parser): Changed to external linkage.
(lisp_parser_impl, read_file_common): Follow rename of
get_parser_impl.

* parser.h (parse_once): Declaration updated.
(parser_get_impl, ensure_parser): Declared.

* parser.y (parse_once): Take self parameter; drop parser
parameter. Ensure a parser to the stream, rather than
declaring one locally. Don't clean up the parser when
done, just let the stream clean it up.

* txr.c (parse_once_noerr): Parser argument is dropped and
not passed to parse_once. Program name is passed as self
argument to parse_once.
(txr_main): When parsing the TXR pattern query, don't define a
parser locally; ensure there is one in the stream and use it,
like in load and v_load.
