fcb4ed054c Preprocessor: Rationalize, simplify, and correct the stack of input sources and their tokenization. This included
- consistently dealing with EOF and its effect on error recovery (bug 11444, #1)
 - turning a simulated OO hierarchy of function pointers and typecasting into a real C++ class hierarchy
 - correctly handling '\' everywhere, in all classes of tokens, as a layer before preprocessing itself
 - conditionally handling '\n' in macro expansion input, depending on whether it is in a macro expression or not
 - delete some unused "memory cleanup" code

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

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
