SAMBA_TNG: status

wow, amazing.  it _is_ possible to just read / write from a unix socket on
SMBreadX, SMBwriteX and SMBtrans.  smbd doesn't care less what the data it
is seeing is, it just sends it on through!

it was a bit of a pain, though.  you remember i said that stuff about
msrpc pdus being multiple fragments (req, req, resp, resp, resp)?  well,
on the msrpc-daemon-side of the unix socket, i had to do a write select()
check before sending on the next resp.

i'm so pleased that i can take out all the msrpc server code from smbd.
