Add ES 3.0 fragment output link-time test for outputs having or not having location qualifiers.

Browse source 
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.

Cross-stage linking
- type consistency check of uniform and ins <-> outs, both variables and blocks, stage-specific arrayness matching
- location/binding/index check
- matching initializers for uniforms
- mixed es/non-es profiles
- statically consumed input not produced by previous stage
- matching between gl_PerVertex blocks and gl_PerFragment blocks
- compute shader not combined with any other stages
- give error for sharing a packed block
- 1.2: matching initializers for uniforms
- 1.5: matching between gl_PerVertex blocks and gl_PerFragment blocks
- 1.3: deprecated mixing fixed vertex/fragment stage with programmable fragment/vertex stage.
- 4.3: compute shader not combined with any other stages
- 4.3: remove cross-version linking restrictions.
- 4.3: Allow mismatches in interpolation and auxiliary qualification across stages.
- 4.4: A stage contains two different blocks, each with no instance name, where the blocks contain a member with the same name.
