First round of quasiliteral-related fixes.
* parser.l: Do not try to recognize floating-point literals
in QSPECIAL state; that is not possible because @134.3
in a quasiliteral parses as a METANUM followed by ".3".
On the other hand, recognize METANUM literals in QSPECIAL state,
so that @@123 scans. Recognize @ as a token in QSPECIAL state,
so @@abc will scan. When transitioning from QSILIT and QWLIT
states to QSPECIAL upon scanning @, return a @ token, which
is now parsed in the grammar.
* parser.y (quasi_meta_helper): New static function.
(q_var): Do not handle SYMTOK any more, only the braced
variable syntax. SYMTOK is handled as a n_expr.
Braced vars are handled with explicit '@' token, which
is now produced by the scanner when it shifts from QSILIT
to QSPECIAL.
(quasi_item): No longer necessary to recognize various
forms here such as quotes and splices. Just recognize a n_expr,
preceded by '@'.
