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.

Idea from: truckman
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.
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.
