5f1a0b7998 Eliminate flex as the GLSL lexical analyzer, going from two nested lexical analyzers down to one, leaving just the preprocessor's lexical analysis. A new layer replaces it, to translate from the preprocessor's view of tokenization to glslang's view of tokenization.
Also:
 - change source locations from an int to TSourceLoc (shader number, line number) throughout
 - various improvements to the preprocessor

73ed17a87b Rationalize naming/access to current thread-local-storage scheme. However, the preprocessor tokenizer is not thread-safe, so this may all change.
Also adding missing test.

1fde51d3fb 1) Don't propagate precision of built-in function arguments to return type when return type is bool (e.g., isnan).
2) Check an additional path for missing default precision qualification, except allow built-in declarations to pass the check.

41cf6b540b Add scanner that can find '#version' across an array of non-null terminated, length-based, strings. Handle the ES error where #version is not the first thing found, while still supporting desktop behavior, and more generally support length-based multiple strings for a single shader.

06f8464fb5 Create linkage symbol nodes in the AST so a linker has access to all global objects that were declared, for error checking, etc. Use it now for all ins/outs/uniforms as well as gl_VertexID and gl_InstanceID.
Also fixed a confusing name and added more 'const'.

bd0747d6f0 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

46eaf4939e 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.

f0fdc53e2a 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

9fd55bd338 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.
