Also
 - uniformly handle EvqConstReadOnly as an input argument in a function, with 
   isParamInput() and isParamOutput() queries in TQualifier.
 - provide a makeTemporary() in TQualifier, for erasing original qualification when making a temp
 - provide a makeInternalVariable() call to make a shader variable not seen in the shader source

5053a39578 Fix slight inconsistencies in which qualifiers are inherited into block members: 
- don't inherit 'binding'
 - always set the member storage qualifier, not just when the shader explicitly set it
 - don't include in/out members as objects that are resized by geometry/primitive layout specifiers
As a side effect, this makes built-in redeclarations (like gl_ClipDistance) require in/out.

fcb4ed054c Preprocessor: Rationalize, simplify, and correct the stack of input sources and their tokenization. This included 
- consistently dealing with EOF and its effect on error recovery (bug 11444, #1)
 - turning a simulated OO hierarchy of function pointers and typecasting into a real C++ class hierarchy
 - correctly handling '\' everywhere, in all classes of tokens, as a layer before preprocessing itself
 - conditionally handling '\n' in macro expansion input, depending on whether it is in a macro expression or not
 - delete some unused "memory cleanup" code

 - built-in variable declarations, some dependent on gl_MaxPatchVertices
 - layout qualifier for vertices (shared with geometry shader max_vertices)
 - layout qualifiers for vertex spacing, vertex order, point mode, and primitive type
 - link semantics for layout qualifiers

Still TBD:
 - patch qualifier and arrayed input handling
 - sizing of gl_out[]
 - additional semantic checking
 - supporting the extension on version 150

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

bd0747d6f0 Built-in symbol tables now lazily evaluated, and driven by per version, per profile input. Got all ES 100 and ES 300 built-in symbols correct. 
This includes
 - doing prescan of shader to know version/profile before parsing it
 - putting precision qualifiers on built-in ES symbols
 - getting most built-in state correct for core/compatibility/missing profile
 - adding gl_VertexID and gl_InstanceID, among other ES 300 built-in symbols
 - adding the ES 300 gl_Max/Min constants
 - accepting shaders that contain nothing but whitespace without generating an error

f0fdc53e2a Implement non-square matrices, and make a few type improvements. Cleaned up a few old issues. Added two tests. 
Details
 - added all the new non-square types
 - separated concepts of matrix size and vector size
 - removed VS 6.0 comments/workarounds
 - removed obsolete concept of matrix fields

1c809955ba Add ability to treat keywords as identifiers in versions that had not yet reserved the keyword. 
Used this for precision keywords and double matrix keywords.

Also added a few missing reserved words.

Also removed redundant "syntax error" when there is a parse error.

9fd55bd338 Add a new shader-versioning infrastructure capable of handling multiple profiles, desktop/ES, many versions, features coming and going in different versions across different profiles, and extensions. 
NB: *Use* of this infrastructure is so far only skeletal.

Fixed a few typos and minor issues along the way.
