Move libnet_conf to a library lib/smbconf/ of its own, fixing the api.
The libnet_conf code to access the registry based configuration has become more of a library used in several places in samba (e.g. loadparm) than an abstraction of "net conf". So I move it to a location lib/smbconf/. In the same breath, the api is fixed (not generated by make proto anymore). Michael (This used to be commit 5315ef41f403b96715dd68b512e9e74662e2910a)
