This commit has two pieces. One half is the watchdog kernel code which lives
primarily in hardclock() in sys/kern/kern_clock.c. The other half is a userland
daemon which, when run, will keep the watchdog from firing while the userland
is intact and functioning.

The matcd.4 man page has been upgraded to reflect current 5.1.x
functionality, and efforts were made to match the style and layout found
in similar-single purpose block drivers man pages found in the 5.1 tree
man4 area while not losing useful information. However, the documentation
folks should still take a look, since the man pages used as guides were
somewhat inconsistent on a variety of points.

Remove a reference to the defunct macro M_COPY_PKTHDR;
document the new functions m_dup_pkthdr() and m_move_pkthdr(),
and the macro variant of the latter, M_MOVE_PKTHDR().
- tagging plaintext "mbuf", "mbuf cluster", and "mbuf chain"
with .Vt (variable type) since all of them are ways of managing
data, i.e., they can be seen as data types;
- using .Vt/.Va instead of .Li (literal) where appropriate;
- tagging plaintext words that actually refer to function arguments
with .Fa.

bus_dmamap_sync() by OR'ing them together.
- Don't document what BUS_DMASYNC_PREREAD|BUS_DMASYNC_PREWRITE and
BUS_DMASYNC_POSTREAD|BUS_DMASYNC_POSTWRITE is supposed to do when
passed to bus_dmamap_sync(). There are other possible combinations
and the reader just needs to know what the individual flags do and
that he can combine different DMA operations.
- Use .An when listing authors.

the tree. Add also a description on how to do this configuration
in the rc.conf script.

While I am there, nuke IF_ENQ_DROP from the list of functions. More
work will be done on this, since some of the functions like
if_enq_drop() and if_queue_drop() were replaced with one function
called if_handoff() that does the job of enqueing the packet and
updating interface statistics as necessary.

It currently supports the PMC Sierra Lite, Ultra and 622 chips and
the IDT 77105. The driver handles media options and state in a consistent
manner for ATM drivers. The next commit to the midway driver will make
it use utopia.

was posted to me.
