connections. While this confuses tcpdump, it enables other applications
to see and analyze non-IP traffic (signalling, for example).

drain routines are done by swi_net, which allows for better queue control
at some future point. Packets may also be directly dispatched to a netisr
instead of queued, this may be of interest at some installations, but
currently defaults to off.

the necesary uma_zcreate() and uma_zdestroy calls into module loading
handler and the device attach handling.
- Change the related HARP netatm code to use UMA zone functions when
dealing with the zones that were formerly the ATM interface (hea, hfa)
storage pools.
- Have atm_physif_freenifs() now get passed an uma_zone_t so that we can
properly free the allocated NIF's back to their zone.
This should be the last commit to remove any code that makes use of the
netatm storage pool api. I will be removing the api code within the near
future.

Define the atm_dev_free() routine so that its OK to free stuff that is defined
as volatile. Note this doesn't FORCE the arguemnts to be volatile,
just says that it's not an error if it is..
before adding/removing packets from the queue. Also, the if_obytes and
if_omcasts fields should only be manipulated under protection of the mutex.
IF_ENQUEUE, IF_PREPEND, and IF_DEQUEUE perform all necessary locking on
the queue. An IF_LOCK macro is provided, as well as the old (mutex-less)
versions of the macros in the form _IF_ENQUEUE, _IF_QFULL, for code which
needs them, but their use is discouraged.
Two new macros are introduced: IF_DRAIN() to drain a queue, and IF_HANDOFF,
which takes care of locking/enqueue, and also statistics updating/start
if necessary.

Also un-nest includes in <dev/hfa/fore_include.h>
I have run src/tools/tools/kerninclude to remove 1239 clearly
unneeded #includes reducing the total from 3524 includes to 2285.
Define the NETISR just like all the other NETISRs.
unifdef -Usun -D__FreeBSD__ we will probably never support sun4c
and if we do we can't use the solaris code anyway and I doubt
anybody will be running Fore ATM cards in then in the first place.
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.
These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.
