envoked -- don't use them (as return values from open()), then
(say) close(STDIN_FILENO) when daemonising.
This is done by grabbing 3 descriptors to /dev/null at startup and
releasing them after we've daemonised.

These take an additional mutex argument, which is dropped before any
processes are made runnable. This can avoid contention on the mutex
if the processes would immediately acquire it, and is done in such a
way that wakeups will not be lost.

This is necessary because MPPE will combine the protocol id with the
payload received on the tun interface, encrypt it, then prepend its
own protocol id, effectively increasing the payload by two bytes.

change the name of the page (.Nm) from "kldstat" to "modstat".
Second, don't claim that modstat(2) always returns 0. Actually,
it behaves as most syscalls do - returns 0 on success, or -1
on failure.

We already did this in the SMP case, and it is now maintained in the UP
case as well, and makes the code slightly more readable. Note that
curproc is always executing, thus the p != curproc test does not need to
be performed if the p_oncpu check is made.
We don't actually need to force a context switch of the current process.
The act of firing the event triggers a context switch to softclock() and
then switching back out again which is equivalent to a preemption, thus
no further work is needed on the local CPU.
backslash as nothing, treat it like a space so that adjacent lines
aren't glued together.

give a bit more information about up to 10 errors encountered during
formatting (unless -q has been specified, of course).
While being here, removed a bitrotten comment in the Makefile, and
kill the old Emacs local variable stuff at the end of fdformat.c
that's no longer useful anway.
