Use new version of open_pipe_creds() function.

Don't attempt to free client state returned by cli_full_connection()

Fix memory leaks on error.

Allow setprinter level 1 - doesn't work though.

Extended interface to enumprinters().  The name value passed in the RPC
request can be different from the server name in which case lots of weird
and wonderful information is returned.  Defaults to the server name.
