More code is removed from the special parser directories and centralized
into grammar.py, Cmd.py, and generate-flex-bison.mk.

grammar.py is meant as a compiler compiler compiler, taking in a grammar

Currently there are still remnants of VHDL-specific stuff in the code,
because parsing VHDL was what it was initially about.
