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
