edafc1a965 Make this compile cleanly. It passes WARNS=2, but I haven't checked
it is so on more platforms.

ac48fcc177 When getting back an NLM DENIED response for a requested lock from the
server, map it to EAGAIN locally rather than EACCES.  The NLM spec
indicates the DENIED corresponds to lock contention, not a permission
failure.  This fixes O_EXLOCK/O_SHLOCK with O_NONBLOCK, which would
previously give a permission error, which in turn fixes things
like mailq(8) and lockf(1) over NFS.

6d7e27aceb Remove a case of exposing 'struct ucred' to userspace. Use a struct xucred
for LOCKD_MSG instead.

7d1e070d0f Drop privs while servicing kernel lock requests.
Restore umask used before FIFO creation.
If opening the FIFO fails, exit.
Properly check the return value of open (use == -1 instead of < 0).

bf67173885 leverage fixed fifo implementation (rev 1.56 of
src/sys/fs/fifofs/fifo_vnops.c) to serve locks better, my previous
workaround for lack of decent fifo system wasn't cutting it,
particularly the kernel would send a message down the fifo and
immediately close it, this would lead to delayed unlock requests
being seen by the lockd causing all sorts of badness.

Basically, don't reopen the fifo, just select(2) on it.

026a60d792 Fix compiling without -O, some dead code was using non-existant functions,
make the code not automatically dead but actually use the debug level
in order to determine if output is needed.  Fix non-existant from_addr()
by #define'ing it to inet_ntoa().

Remove hardcoded -g from Makefile.
