27151efa71 Tessellation: Smaller changes: Take tessellation control output arrayness into account in location overlap testing, better error message for redeclaring a built-in with size to be unsized.

f3e2a89452 Tessellation: Implicit array sizing and consistency checking of control-shader output arrays based on layout(vertices=...).

3a4687d782 Add missing check that a function call is not using the same name as a variable hiding the function's name. Also, support version 110 separate name spaces for functions and variable names.

623833fabc 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

521ca375e0 Remove one layer of arrayness on geometry shader inputs before checking for location overlaps. I think there is a spec. bug here.

5134b9cf57 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.

11f9fc7247 Add and partially implement an interface for doing uniform reflection. It includes an AST traversal to identify live accesses.
It does not yet correctly compute block offsets, give correct GL-API-style type values, or handle arrays.

This is tied to the new -q flag.

fb57e7cc5e Add ES 3.0 fragment output link-time test for outputs having or not having location qualifiers.
Also split linker validation into its own file, removed dead "QualifierAlive" files, printed errors for parsing problems with built-in symbols,  updated the Windows binary, and added some tests.
