4d6570a1b3 Fix several issues in the preprocessor: 
- macro expansion of hexidecimal numbers 
 - give errors instead of warnings/silence on extra tokens after #endif, #else, etc.
 - give errors on reserved macro name use, reuse of argument, and redefinition with different whitespace presence
 - detect and give error for all cases of #elif and #else after #else

ea869fb403 Improve preprocessor by using GLSL scanner, allowing read-only strings to be compiled, unifying of line # tracking, and correct detection that ES #version appeared after a comment.

e50441ad94 Make some portability improvements identified by Christophe: A few size_t, a couple "../Include", and a whole bunch of parenthesizing "(A && B) || (C && D)", because some compilers don't believe humans know && is higher precedence than ||.

b603f918a4 Put all glslang internals (but not the external interface) into the glslang namespace.

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

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.
