c675522fc4 Re-implement the client side of rpc.lockd in the kernel. This implementation
provides the correct semantics for flock(2) style locks which are used by the
lockf(1) command line tool and the pidfile(3) library. It also implements
recovery from server restarts and ensures that dirty cache blocks are written
to the server before obtaining locks (allowing multiple clients to use file
locking to safely share data).

098935f8d5 If the mmap() call in rpc.statd fails, rpc.statd prints a warning
message and then dumps core because the subsequent code assumes that
mmap() succeeded.  Since rpc.statd does not have fallback code to
implement the functionality needed to operate on the status file if
it is not memory mapped, rpc.statd should use err() to force the process
to exit if the mmap() call fails.

422e293c7f Deal with xdrproc_t casts. Make these compile cleanly with WARNS=2
(but I haven't turned it on)

4c96ae1554 Included in the updated version of tirpc's sm_inter.x Sun added the
SM_NOTIFY procedure.

Remove our hand-coded one as it was causing world breakage for
worlds compiled with NOSHARED=yes because the static linker is a
bit less forgiving (or not as broken as) our dynamic linker.

Add $FreeBSD$ while I'm here.

8abdc2eb40 Sweep through the tree fixing mmap() usage:
- Use MAP_FAILED instead of the constant -1 to indicate
    failure (required by POSIX).
  - Removed flag arguments of '0' (required by POSIX).
  - Fixed code which expected an error return of 0.
  - Fixed code which thought any address with the high bit set
    was an error.
  - Check for failure where no checks were present.

1494289f5b Import Jan 15 version of Andrew Gordon <andrew.gordon@net-tel.co.uk>'s
rpc.statd.

This is apparently fully functional and complete.
