jeremy is going to hate me for this.

created an "nmb-agent" utility that, yes: it connects to the 137 socket
and accepts unix socket connections which it redirects onto port 137.

it uses the name_trn_id field to filter requests to the correct
location.

name_query() and name_status() are the first victims to use this
feature (by specifying a file descriptor of -1).
(This used to be commit d923bc8da2cf996408194d98381409191dd81a16)
