syntax: be tolerant of carriage returns.

This is needed for multi-line mode with CR line breaks.
It also makes TXR tolerant when code is ported among
systems with different line endings.

* parser.l (NL): New lex named pattern, matching three
possible line terminators: CR, NL or CR-NL.
(grammar): In places where \n was previously matched,
use {NL}. In a few places where \n is in a character
class, add \r. In one place (comment matching), the
the pattern . which implicitly doesn't match newlines
had to be replaced with [^\r\n].
