remove python bindings

[pmenzel]

Well, the motivation for removing the Python bindings is not documented. Also, that currently GDB is broken after the Python system changes.

I do not use the Python bindings yet, but they are supposed to be quite handy when debugging stuff. But a working GDB is better than a broken one. Hopefully, it can be fixed in the future.

@paul, can you provide an usecase where we need the Python features?
