the first independent msrpc daemon - lsarpcd.

one horrible cut / paste job from smbd, plus a code split of shared
components between the two.

the job is not _yet_ complete, as i need to be able to do a become_user()
call for security reasons.  i picked lsarpcd first because you don't
_need_ security on it (microsoft botched so badly on this one, it's not
real.  at least they fixed this in nt5 with restrictanonymous=0x2).
fixing this involves sending the current smb and unix credentials down
the unix pipe so that the daemon it eventually goes to can pick them
up at the other end.

i can't believe this all worked!!!
