Clean up a few unused functions, add a bit of static etc.

Importantly:

The removal of the silly 'delete user script' behaviour when secuity=domain.

I have left the name the same - as it still does the (previously documented,
but not in smb.conf(5)) sane behaviour of deleting users on request.

When we decide what to do with the 'add user' functionality, we might
rename it.
