Modulize Group mapping

[Stefan (metze) Metzmacher]

Hi,

I've startet to make the group mapping code modulized in the way it is done 
in the auth and passdb subsystems.

Here is my first version of the module API.

I want to add a paramter:
group mapping backend = tdbsam

tdbsam should be the default.

Comments please!
