29ad26f932 Major update of NCP requester:
Use mchain API to work with mbuf chains.

Do not depend on INET and IPX options.

Allocate ncp_rq structure dynamically to prevent possible stack overflows.

Let ncp_request() dispose control structure if request failed.

Move all NCP wrappers to ncp_ncp.c file and all NCP request processing
functions to ncp_rq.c file.

Improve reconnection logic.

Misc style fixes.

fffd12bd72 Implement m_getm() which will perform an "all or nothing" mbuf + cluster
allocation, as required.

If m_getm() receives NULL as a first argument, then it allocates `len'
(second argument) bytes worth of mbufs + clusters and returns the chain
only if it was able to allocate everything.
If the first argument is non-NULL, then it should be an existing mbuf
chain (e.g. pre-allocated mbuf sitting on a ring, on some list, etc.) and
so it will allocate `len' bytes worth of clusters and mbufs, as needed,
and append them to the tail of the passed in chain, only if it was able
to allocate everything requested.

If allocation fails, only what was allocated by the routine will be freed,
and NULL will be returned.

Also, get rid of existing m_getm() in netncp code and replace calls to it
to calls to this new generic code.

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.

da71e9a21b Make malloc use M_ZERO in some more locations.
Don't check for a null pointer if malloc called with M_WAITOK.

a18b1f1d4d Convert lockmgr locks from using simple locks to using mutexes.
Add lockdestroy() and appropriate invocations, which corresponds to
lockinit() and must be called to clean up after a lockmgr lock is no

664a31e496 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.
