Change infrastructure to support constant folding across built-in functions, as required by 1.2 semantics. Partially fleshed out with min/max and some trig functions. Still have to complete all operations.

Add productions/data for about 14 qualifiers (versions 1.2 through 4.3). Fixed some case issues for rect/array keywords.

Built-in symbol tables now lazily evaluated, and driven by per version, per profile input. Got all ES 100 and ES 300 built-in symbols correct.
...
This includes
- doing prescan of shader to know version/profile before parsing it
- putting precision qualifiers on built-in ES symbols
- getting most built-in state correct for core/compatibility/missing profile
- adding gl_VertexID and gl_InstanceID, among other ES 300 built-in symbols
- adding the ES 300 gl_Max/Min constants
- accepting shaders that contain nothing but whitespace without generating an error

Support multiple default versions, to enable ES vs. desktop contexts, for shaders missing a #version statement.
...
This also moved some parseContext code from the flex file to the proper C++ file.

Implement non-square matrices, and make a few type improvements. Cleaned up a few old issues. Added two tests.
...
Details
- added all the new non-square types
- separated concepts of matrix size and vector size
- removed VS 6.0 comments/workarounds
- removed obsolete concept of matrix fields

Add a new shader-versioning infrastructure capable of handling multiple profiles, desktop/ES, many versions, features coming and going in different versions across different profiles, and extensions.
...
NB: *Use* of this infrastructure is so far only skeletal.
Fixed a few typos and minor issues along the way.

Add arrays of arrays grammar, and adapt existing 1D array semantics to keep working as before.
...
Also add buffer and shared keywords and grammar, which brings the grammar up to 4.3.
N.B. There is a problem for "shared": it is both a keyword (as a storage qualifier) and an identifier (for layouts).

Remove the pack/unpack languages and bring grammar up from 1.1 to 4.2 and fix the affected 1.1 productions and semantics to still work correctly for 1.1 shaders.
...
For 4.2, largely, it is only the grammar that is working. Productions and semantics are mostly missing. Lexical analysis is mostly done, but not in the preprocessor, which still can't handle uint and double literals.
The grammar and token names are reorganized to match the specification, to allow easier comparison between the specification and the working grammar.
