Reorganize an_detach() a bit. Make sure ether_ifdetach() and if_free()
are called outside of AN_LOCK()/AN_UNLOCK. This fixes the following
WITNESS warning (produced when an(4) PCMCIA card is detached).
taskqueue_drain with the following non-sleepable locks held:
exclusive sleep mutex an0 (network driver) r = 0 (0xc59af168) locked @ /usr/src/
sys/dev/an/if_an.c:2836
Do not lock an to check gone flag. Only need to hold the lock to set
the gone flag.

memstat_uma.c:1.9 from HEAD to RELENG_6:
Correct two libmemstat(3) bugs:
- Move memory_type_list flushing logic from memstat_mtl_free() to
_memstat_mtl_empty(), a libmemstat-internal function that can
be called from other parts of the library. Invoke
_memstat_mtl_empty() from memstat_mtl_free(), which also frees
the containing list structure.
Invoke _memstat_mtl_empty() instead of memstat_mtl_free() in
various error cases in memstat_malloc.c and memstat_uma.c, which
previously resulted in the list being freed prematurely.
- Reverse the order of updating the mt_kegfree and mt_free fields
of the memory_type in memstat_uma.c, otherwise keg free items
won't be counted properly for non-secondary zones.
Merged to RELENG_6 earlier than the proposed MFC after date so that it
can make BETA2.

Fix the way how "InUse" column in 'vmstat -m' output works:
- increase number of allocations count only on successfull malloc(9),
so it doesn't confuse people;
- because we need to check if 'size > 0', hide 'mtsp->mts_memalloced += size;'
under the check as well, as for size=0 it is of course a no-op;
- avoid critical_enter()/critical_exit() in case of failure in
malloc_type_allocated() as there will be nothing to do.

- Don't complain when debouncing dhclient startup.
- Fix buffer handling in reveive_packet(). This fixes infinite cpu
eating loops and probably some crashes.
- Spell if_defaultroute route correctly in dhclient-script so we
are allowed to change the default route.
- Document dhclient -b.
- Treat reassociation like association.
- Do not force server-name to be a valid domain name.
- Handle servers that send NUL-terminated host-name options.

Add back ed(4) in amd64 GENERIC. It now works nicely and since those

Allow PLAY_MSF, PLAY_TRACK, PLAY_TRACK_REL, PAUSE, PLAY_12 commands to pass
through umass(4), in order to make cdcontrol(1) to issue commands to a USB

The command IDs were obtained from the CAM subsystem. This was tested
on half dozen of USB CD drivers from different vendors.

Modify "netstat -mb" to use libmemstat(3) when acting on a live system,
with a number of positive benefits:
- Start using UMA(9) statistics for mbufs and clusters, which avoids
using the mbuf allocator statistics which suffer from races under
load on SMP. This should eliminate "negative" mbuf counts in
netstat -mb.
- We are now able to track cached (free) mbufs and clusters and count
it towards memory allocated by the network stack.
- We are now also able to track memory allocated to mbuf tags since
libmemstat(3) can also query malloc(9). We don't print this except
as part of the total (for now - #if 0).
- We are now able to track mbuf/cluster/packet allocation failures,
although they are not currently printed (#if 0).
- Don't print out sfbuf statistics when running on a kernel core, as
currently that code is able only to query sysctl for statistics.
mbuf.c:1.44:
Since libmemstat(3) now supports its own error management mechanism,
use that instead of trying to use errno, in order to produce a
sensible error message.

Rename UMA_MAX_NAME to UTH_MAX_NAME, since it's a maximum in the
monitoring API, which might or might not be the same as the internal
maximum (currently none).
Export flag information on UMA zones -- in particular, whether or
not this is a secondary zone, and so the keg free count should be
considered in that light.
