parser: remove some wasteful string object allocations.

* lib.c (int_str_wc): New function, made out of int_str.
This can be used by the parser to work with a wchar_t *
string without having to create a string object.
(int_str): Implemented in terms of int_str_wc.

* parser.l (grammar): Remove string_own calls from numerous
rule bodies that use int_str to return a number.
These rules now capture the wchar_t string, pass it to
int_str_wc and then immediately free it. Whereas string_own
allocates an extra object and leaves it to the garbage
collector.

* lex.yy.c.shipped: Regenerated.
