Anything that matched IDENTIFIER was strdup'ed and returned to the
parser. However, almost every case of IDENTIFIER in the parser just
dropped the returned string on the floor. Every swizzle string, every
option string, every use of a variable, etc. leaked memory.
Create a temporary buffer in the parser state (string_dumpster and
dumpster_size). Return strings from the lexer to the parser in the
buffer. Grow the buffer as needed. When the parser needs to keep a
string (i.e., delcaring a new variable), let it make a copy then.
The only leak that valgrind now detects is /occasionally/ the copy of
the program string in gl_program::String is leaked. I'm not seeing
how. :(

See bug 24531.

Fixes compilation warnings with MSVC.

Fixes symbol collisions with typedefs in Microsoft headers.
Perhaps we should prefix/suffix all the lexer tokens to avoid this.

This isn't really tested yet as no drivers actually support this extension.

Passes the piglit asmparsertest shadow-0[123].txt tests and
progs/demos/shadowtex.

Require that GL_{ARB,EXT,NV}_texture_rectangle be supported before
allowing use of RECT texture target.

Valgrind doesn't complain about a leak here, so delete the comment
about possibly needing to free the state returned by yy_scan_bytes.

This still needs quite a bit of work, but a bunch of the programs in progs/vp
produce correct results.
