0876a58203 Misc. constant-folding fixes: Check % for 0, mat(mat) constructor, index range checking (within constant objects). Also, rationalize addConst*() methods.

f2ee3dd46a Add full support for uniforms with initializers, including intra-stage link validation of aggregate constant initializers.
This included 
 - encapsulating aggregate constants
 - removal of constant-aggregate comparison algorithms, instead using a flattened and direct std::vector comparison
 - adding structure type comparison for independently declared structures that still might match types

9839e2440e Unify the 8 grammar productions for declaring variables. This greatly simplifies making changes for this set of productions.

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

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
