e8fe7b81d7 Allow tessellation shaders to work on versions back to 150. Also combined all the tessellation tests into a single run.

bd95819123 1) Allow '\' before a non-newline as a token in the preprocessor, and 2) localize line-continuation to just the pp scanner.

d6bef9186b Correct textureGather*() extension support: 
- add extension behavior and warning message for partial extension support
 - add partial support for gpu_shader5 for textureGather*
 - add interactions between texture rectangle and textureGather*
 - add checks to distinguish between gpu_shader5 and texture_gather extension feature differences

bd1a5b7727 Add GL_OES_EGL_image_external. Includes new keyword, type, name mangling, built-in function calls, etc.

115a0adc29 Add GL_OES_texture_3D extension. Also, minor tweaks to extension adding infrastructure.

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.

c973c004d4 Non-functional: Use better token names for the preprocessor.

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 ||.

5f753e0222 Full thread safety working: 
- don't use [] for map lookups, it can modify the map
 - copy up built-in symbols out of shared symbol table levels before modifying them
 - enforce shallow vs. deep TType copies
 - combine maxArraySize with the array dimensions vector, encapsulate
 - remove chaining of array types

38f3b890de Ensure the shared symbol table levels are read-only to make multi-threading safe. Also removed inadvertent extra copies of the symbol table shared across all stages.

2f1eb37d82 Some rationalization of TIntermediate (to own it's own tree root) and TParseHelper for better encapsulation. Needed by some upcoming intra-stage link validation.

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

7213324259 Reframe the preprocessor as a C++ class, with instances, removing all C code, removing all global variables. Upgrade bison version to pass a parse context on through to the preprocessor. All the basic things to make something thread safe.

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.
