18d5982009 Update these netgraph drivers in current so that these changes can be
MFC'ed i due time.  I can't test it under current right now because
netgraph seems to do unethical things with mutexes.

musycc:
	Add status per channel.
	Reduce printf chattyness
	Keep error counters line if_mn does.
	Increase descriptor count.

if_mn:
	Support experimental unframed E1 lines.

These two drivers should share more code relating to framed channelized
TDM media in general (T1/E1/E3/T3, Sonet).  Anyone interested email me.

a1c9b755a7 Use pci_get_revid() rather than groping around the PCI register space
using the removed compatability register names.  (this broke LINT)

30400f03aa Part 2 of the netgraph rewrite.
This is mostly cosmetic changes, (though I caught a bug or two while
makeing them)

069154d55f Rewrite of netgraph to start getting ready for SMP.
This version is functional and is aproaching solid..
notice I said APROACHING. There are many node types I cannot test
I have tested: echo hole ppp socket vjc iface tee bpf async tty
The rest compile and "Look" right.  More changes to follow.
DEBUGGING is enabled in this code to help if people have problems.

2a0c503e7a * Rename M_WAIT mbuf subsystem flag to M_TRYWAIT.
This is because calls with M_WAIT (now M_TRYWAIT) may not wait
  forever when nothing is available for allocation, and may end up
  returning NULL. Hopefully we now communicate more of the right thing
  to developers and make it very clear that it's necessary to check whether
  calls with M_(TRY)WAIT also resulted in a failed allocation.
  M_TRYWAIT basically means "try harder, block if necessary, but don't
  necessarily wait forever." The time spent blocking is tunable with
  the kern.ipc.mbuf_wait sysctl.
  M_WAIT is now deprecated but still defined for the next little while.

* Fix a typo in a comment in mbuf.h

* Fix some code that was actually passing the mbuf subsystem's M_WAIT to
  malloc(). Made it pass M_WAITOK instead. If we were ever to redefine the
  value of the M_WAIT flag, this could have became a big problem.

589f6ed8ce Divorce the kernel binary ABI version number from the message
format version number. (userland programs should not need to be
recompiled when the netgraph kernel internal ABI is changed.

Also fix modules that don;t handle the fact that a caller may not supply
a return message pointer. (benign at the moment because the calling code
checks, but that will change)

38d66a0de3 Make sure to check if MGET(HDR) returned NULL, even when called with M_WAIT.
This fixes the possibility of a NULL pointer dereference in the case where
there are no mbufs or mbuf clusters left.

e0752f9a73 I really hate it when part of a patch gets left out.
This was still sitting in my commit tree.
Luckily I always compare my before and after trees...

This clears out my outstanding netgraph changes.
There is a netgraph change of design in the offing and this is to some
extent a superset of soem of the new functionality and some of the old
functionality that may be removed.

This code works as before, but allows some new features that I want to
work with and evaluate. It is the basis for a version of netgraph
with integral locking for SMP use.

This is running on my test machine with no new problems :-)

c447342094 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

25792ef324 Change the prototype of the strto* routines to make the second
parameter a char ** instead of a const char **.  This make these
kernel routines consistent with the corresponding libc userland
routines.

Which is actually 'correct' is debatable, but consistency and
following the spec was deemed more important in this case.
