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

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.

12f9221e44 Reflection:
- correct block data size
 - handle deep dereference chains (block.member.member.member)
 - more clear interface argument names

(Still TBD: optimizing array size based on biggest used index and handling variable array index in middle of deep dereference chain)

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.

9839e2440e Unify the 8 grammar productions for declaring variables. This greatly simplifies making changes for this set of productions.
This change also naturally picks up redeclarations of built-in arrays and the addition of the remaining linker objects of const, arrays, etc.

337dbc7d8c Add basic intra-stage linking validation for matching types and qualification of uniforms/ins/outs/globals, function body duplication, and mixing ES/non-ES shaders.
Still need to handle arrays and built-in redeclarations, and many more rules, but this puts the basics in place.

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.
