Fix the few non-portable uses of "char" (where a -1 might be relevant): All uses of char are now either "int", "unsigned char" or char arrays for storing strings. Also, went to consistent "char* foo" coding convention. (There were only a few ambiguous uses.)

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

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.

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 ||.

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

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.
