which will eventually try all resolution methods setup in smb.conf
- only resolution backend at the moment is bcast, which does a
parallel broadcast to all configured network interfaces, and takes
the first reply that comes in (this nicely demonstrates how to do
parallel requests using the async APIs)
- converted all the existing code to use the new resolve_name() api
- removed all the old nmb code (yay!)
(This used to be commit 239c310f25)
