This fixes various issues related to gcc's strict-aliasing warning
by using unions. It also handles various cases hit with
gcc's missing-declarations warning.
This fixes a bug where a token that could be a keyword in one version
is not a keyword in another version, but treated like a non-member after
a "." dereference.
Added some const as well. This will remove camouflage of the next commit,
which will add the bulk of Array of Array semantics and functionality.
(Note the basic grammar and data structure is already in place.)
Fixes issue #25. (char 255 aliased to -1 and missing tests for end of input).
1) All layers of input scanning now share a single EndOfInput value.
This avoids translation of it across layers of encapsulation.
2) Some places looking for end of line were not stopping on EndOfInput.
3) Use of "char" for the input made char values > 127 be negative numbers.
This allowed for aliasing of 255 to -1, etc. This is fixed by using
unsigned char.
This simplification is a prelude to eliminating what I appear unnecessary
symbol inserts into tables when tokenizing in the preprecessor, which
show up as taking notable time. (Performance issue.) It also simply makes
the preprocessor easier to understand, which it is badly in need of.
Lots of places in the code use extensionsTurnedOn(1, ...). This
patch introduces a new method, extensionTurnedOn(), for testing
if a single extension is turned on.
- member initializing order in some constructors
- missing default branches in switch-case
- uninitialized variable if switch-case default (uncritical because
program would exit)
- && and || brace warnings in if()
New extensions in glext.h follow the pattern:
#ifndef GL_ARB_texture_rectangle
#define GL_ARB_texture_rectangle 1
#define GL_TEXTURE_RECTANGLE_ARB 0x84F5
#define GL_TEXTURE_BINDING_RECTANGLE_ARB 0x84F6
#define GL_PROXY_TEXTURE_RECTANGLE_ARB 0x84F7
#define GL_MAX_RECTANGLE_TEXTURE_SIZE_ARB 0x84F8
#endif /* GL_ARB_texture_rectangle */
Versions.h tries to declare:
const char* const GL_ARB_texture_rectangle = "GL_ARB_texture_rectangle";
Which means, if you've included glext.h before Versions.h, that the
compiler will see "const char* const 1 = ...", and rightly refuse to
continue.
The ham-fisted approach taken here is to rename the variables in
Versions.h with a leading underscore. This does sort of undermine the
comment about "better to have the compiler do spelling checks", but.

Add defaultProfile and forceDefaultVersionAndProfile into shader
compilation interface.
forceDefaultVersionAndProfile allows us to force parsing the input
shaders using defaultVersion and defaultProfile, regardless of
the #version directive in input shaders.
These two parameters enables us to programmatically invoke glslang
but specify version and profile from somewhere else like command
line.
