Add python-lxc based on the new liblxc API.

This adds a basic python binding done in C and a python overlay to
extend some features and provide a user-friendlier API.

This python API only supports python 3.x and was tested with >= 3.2.

It's disabled by default in configure and can be turned on by using
--enable-python.

A basic example of the API can be found in src/python-lxc/test.py.
More documentation and examples will be added soon.
