Correct textureGather*() extension support:
...
- add extension behavior and warning message for partial extension support
- add partial support for gpu_shader5 for textureGather*
- add interactions between texture rectangle and textureGather*
- add checks to distinguish between gpu_shader5 and texture_gather extension feature differences

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

NB: *Use* of this infrastructure is so far only skeletal.
Fixed a few typos and minor issues along the way.
