new C parser

hi there,

this is just a little notice to let you know that I'v
been working on a new C parser backend for synopsis,
based on libSynopsis (instead of the existing ctool).

The code is highly experimental but I expect it to mature
and stabilize soon (it's refreshing to work on C parsing
after so many headaches over C++ :-)

I'd very much welcome any feedback or help in testing
and development. The code is in contrib/C/. It's not
compiled by default, i.e. to compile it you have to
run 'make' from within build/temp-<platform>/contrib/C
after running 'python setup.py config' (at least) and then
use the usual 'python synopsis.py...' interface to execute it.

My current plans are to finish the C parser and fix the
most important bugs from http://synopsis.fresco.org/issues/bug,
such that I can release version 0.8 around Easter.

As always, feedback is highly appreciated !

Stefan
