so_timeo Used as a sleep/wakeup address, no locking.
sb_* Almost all socket buffer fields locked with
sockbuf lock for the oskcet buffer.
so_cred Static after socket creation.
* Restore directories with 0700 permissions initially,
then use the fixup pass to correct the permissions
* Trim trailing "/" and "/." in mkdirpath()

using rawcb_mtx. Hold this mutex while modifying or iterating over
the control list; this means that the mutex is held over calls into
socket delivery code, which no longer causes a lock order reversal as
the routing socket code uses a netisr to avoid recursing socket ->
routing -> socket.
Note: Locking of IPsec consumers of rawcb_list is not included in this
commit.
ALTQ enabled versions of IFQ_* macros by default, as requested by serveral
others. This is a follow-up to the quick fix I committed yesterday which
turned off the ALTQ checks for non-ALTQ kernels.

The problem was that I was using the unified base address of the module
instead of finding the start address of the section in question.

Obtained from: BSD/OS (byte order), some old libnet stuff I did years ago.
1. Remove a race whereby contigmalloc() would deadlock against the
running processes in the system if they kept reinstantiating
the memory on the active and inactive page queues that it was
trying to flush out. The process doing the contigmalloc() would
sit in "swwrt" forever and the swap pager would be going at full
force, but never get anywhere. Instead of doing it until the
queues are empty, launder for as many iterations as there are
pages in the queue.
2. Do all laundering to swap synchronously; previously, the vnode
laundering was synchronous and the swap laundering not.
3. Increase the number of launder-or-allocate passes to three, from
two, while failing without bothering to do all the laundering on
the third pass if allocation was not possible. This effectively
gives exactly two chances to launder enough contiguous memory,
helpful with high memory churn where a lot of memory from one pass
to the next (and during a single laundering loop) becomes dirtied
again.
I can now reliably hot-plug hardware requiring a 256KB contigmalloc()
without having the kldload/cbb ithread sit around failing to make
progress, while running a busy X session. Previously, it took killing
X to get contigmalloc() to get further (that is, quiescing the system),
and even then contigmalloc() returned failure.

* Usage goes to stderr, not stdout
* Use correct argument markup
* bsdtar --help no longer exits with an error return code
* ensure that the word "bsdtar" appears in the first
line output from "bsdtar --help" (even if the program is
invoked as "tar")
In particular, scripts can now test for the presence of bsdtar.
For example, in /bin/sh:
if (tar --help 2>&1 | grep bsdtar >/dev/null 2>&1) then \
echo bsdtar; else echo not bsdtar; fi
"machine name" in ntalkd(8) request packets, when the destination
and source are local.
This should make talk(1) use much more pleasant for those security-
conscious individuals who have chosen to bind talkd to "localhost".
Previous to this change, talk(1) would require that the hostname of
the machine, as retrieved by gethostname(3), resolved to a valid and
reachable IPv4 address, using gethostbyname(3).
This makes talk(1) dependent on a valid host entry for "localhost"
in /etc/hosts (or the Domain Name System).
