receiver was not sending an immediate ack with delayed acks turned on
when the input buffer is drained, preventing the transmitter from
restarting immediately.
Propogate the TCP_NODELAY option to accept()ed sockets. (Helps tbench and
is a good idea anyway).
Some cleanup. Identify additonal issues in comments.

1) Use devfs to mount filesystems. If mounting devfs is fail,
fallback to old code.
2) When fscking filesystems, use 'fsck_ffs' explicitly. As a
result, we no longer need 'fsck' the wrapper program.

released management apps.
1. Implement poll(). This will check for queued aif's so that a
subsequent ioctl call to retrieve the next aif will not block.
2. Don't catch signals when sleeping on a fib sent from userland. This
causes a race and panic due to the pthread context switcher waking
up the tsleep at inopportune times.
3. Fix some whitespace nits.

<security/pam_misc.h>. It declares a function parameter named 'send',
so nothing that includes both <unistd.h> (which declares send(2)) and
<security/pam_misc.h> be compiled with WARNS=2 unless NO_WERRROR is
set.
Fixed order of WARNS.
Since userconfig feature is implemented by tweaking variables (hint.*)
with loader(8), we can put back an equivalent feature. Maybe the first
step for this is to commit yokota-san's patch (add userconfig command
for loader).

you run out of mbuf address space.
kern/subr_mbuf.c: print a warning message when mb_alloc fails, again
rate-limited to at most once per second. This covers other
cases of mbuf allocation failures. Probably it also overlaps the
one handled in vm/vm_kern.c, so maybe the latter should go away.
This warning will let us gradually remove the printf that are scattered
across most network drivers to report mbuf allocation failures.
Those are potentially dangerous, in that they are not rate-limited and
can easily cause systems to panic.
Unless there is disagreement (which does not seem to be the case
judging from the discussion on -net so far), and because this is
sort of a safety bugfix, I plan to commit a similar change to STABLE
during the weekend (it affects kern/uipc_mbuf.c there).

It defaults to '1', which permits access, but if set to '0', requires
that the process making the sysctl() have appropriate privilege.
o Note that for this to be effective, access to this data via system
logs derived from /dev/klog must also be limited.
