Tessellation partial implementation (not ready for use yet), including:
...
- the built-in constants
- 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

Track what ins/outs/uniforms are used, so that errors like "declare after use" or "can't use both XXX and YYY" can be issued. So far, used this for invariant, gl_FragColor et. al., and gl_FragCoord use before redeclaration.

Also made all tests in testlist include linker tests.

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

Remove the pack/unpack languages and bring grammar up from 1.1 to 4.2 and fix the affected 1.1 productions and semantics to still work correctly for 1.1 shaders.
...
For 4.2, largely, it is only the grammar that is working. Productions and semantics are mostly missing. Lexical analysis is mostly done, but not in the preprocessor, which still can't handle uint and double literals.
The grammar and token names are reorganized to match the specification, to allow easier comparison between the specification and the working grammar.
