John Kessenich [Sat, 6 Jul 2013 19:54:21 +0000 (19:54 +0000)]

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
