05a7063007 Add optional configuration file for specifying (existing) limits. Details explained by usage statement. More limits to be added in the future.

b84b700d90 Basic infrastructure for redeclaring built-in variables (like gl_FragCoord) so shaders can change their type/layout. 
A modifiable copy is made at the shader's global scope.

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

c027579631 Put in infrastructure for tessellation, geometry, and compute stages, and partially flesh out with built-in functions. 
Added the built-in functions EmitVertex(), EndPrimitive(), barrier(), memoryBarrier(), memoryBarrierAtomicCounter(), memoryBarrierBuffer(), memoryBarrierImage(), memoryBarrierShared(), and groupMemoryBarrier().

Have not added any new built-in variables.

Also changed the linear performance relateToOperator() to a high-performance version.

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
