Restore the code that avoided closing and reopening
stdin. This is also required by POSIX. As a bonus,
enable multiple stdin reads with the -benstv flags,
by resetting the EOF condition on stdin.
in vn_rdwr_inchunks(), allowing other processes to gain an exclusive
lock on the vnode. Specifically: directory scanning, to avoid a race to the
root directory, and multiple child processes coring simultaniously so they
can figure out that some other core'ing child has an exclusive adv lock and
just exit instead.
This completely fixes performance problems when large programs core. You
can have hundreds of copies (forked children) of the same binary core all
at once and not notice.

Many people like to use generic devices in rc.syscons, etc..
So rc.devfs needs to run before those rc files.

We still have to account for a copyin. Make sure the copyin will
succeed by passing the FreeBSD syscall a pointer to userspace,
albeit one that's automagically mapped into kernel space.

for securelevel_ge() and securelevel_gt(), I was a little surprised,
but fixed it. Turns out that it was the code that was inverted, during
a whitespace cleanup in my commit tree. This commit inverts the
checks, and restores the comment.
refers to the size of the whole ethernet packet, just the DHCP
message within the UDP payload, or something else. bootpd interpreted
it as a maximum UDP payload size, so it could end up sending
fragmented packets to clients (such as some versions of Etherboot)
that used different interpretations of the maximum message size.
Switch to the most conservative interpretation: ensure that the
ethernet packet containing the response is no larger than the
specified maximum message size. This matches the behaviour of
the ISC dhcpd.

right; after a single packet was dropped it beeped after every
transmission.
Change its implementation to only output a bell when there is an
increase in the maximum value of the number of packets that were
sent but not yet received. This has the benefit that even for very
long round-trip times, ping -A will do roughly the right thing
after a few inital false-positives.

This fixed the problem on the 3 platforms I've been able to test on.
I'm still of the oppinion that the BIOS should take care of this,
however some board makers only apply this when they spot a
SBLive! soundcard, but the problem exists even without a SBLive!.
This fix should probably go somewhere else, but for now I'll
keep it here since we havn't got a central place to put
such things.
