Grammar package supporting 8-bit registers.

TODO:
  - add checking for duplicate symbols (or is it done already?)
  - move all the statics (grammar objects list and last error message)
    to the GL context state; I think simple pointer initialized in a
    first call to ProgramString() is sufficent.
  - apply an optimized version of match() - this will be needed for
    glslang compiler.
