OK. Smbpasswd -j is DEAD.

This moves the rest of the functionality into the 'net rpc join' code.

Futhermore, this moves that entire area over to the libsmb codebase, rather
than the crufty old rpc_client stuff.

I have also fixed up the smbpasswd -a -m bug in the process.

We also have a new 'net rpc changetrustpw' that can be called from a
cron-job to regularly change the trust account password, for sites
that run winbind but not smbd.

With a little more work, we can kill rpc_client from smbd entirly!
(It is mostly the domain auth stuff - which I can rework - and the
spoolss stuff that sombody else will need to look over).
