Preprocessor:  Implement skipping of macros that evaluate to nothing while evaluating expressions.  They had been causing early termination of an expression's evaluation.

Also includes some unrelated updates of documentation.

Preprocessor:  Fixed that some comments incorrectly substituted a new line instead of space.  Also generally cleaned up the space-related coding.

Add #line functionality to allow expressions instead of just literals.  Also made some preprocessor code slightly more clear.

 - Partial fix for new lines in the middle of macro invocation

 - add partial support for gpu_shader5 for textureGather*
 - add interactions between texture rectangle and textureGather*
 - add checks to distinguish between gpu_shader5 and texture_gather extension feature differences

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.

Reflection: Flesh out expansions of complex aggregates not fully dereferenced, visit all array elements for a variable index, and correct max array index when a later occurrence is larger than an earlier one.

 - 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)
