Make the PP report an error on undefined macro in "#if ..." for ES profiles, unless relaxed error checking is requested.  Still works as normal CPP on non-ES.

Also, improved error reporting in general for the PP.

Built-in symbol tables now lazily evaluated, and driven by per version, per profile input.  Got all ES 100 and ES 300 built-in symbols correct.

This includes
 - doing prescan of shader to know version/profile before parsing it
 - putting precision qualifiers on built-in ES symbols
 - getting most built-in state correct for core/compatibility/missing profile
 - adding gl_VertexID and gl_InstanceID, among other ES 300 built-in symbols
 - adding the ES 300 gl_Max/Min constants
 - accepting shaders that contain nothing but whitespace without generating an error
