Replace sconfig with a C implementation.

Browse Source 
(smaller, faster, standard parser generator, no more python)

Provide precompiled parser, so bison and flex are optional dependencies.

Adapt Makefile and abuild (which uses some sconfig file as a
magic path) to match.

Drop python as dependency from README, and add bison and flex
as optional dependencies
