smbfs_close(). This fixes paging to and from mmap()'d regions of smbfs
files after the descriptor has been closed, and makes thttpd, GNU ld,
and perhaps more things work that depend on being able to do this.

A PPP login program is started _automatically_ (i.e., without
human intervention) even with the "pl" capability unset, as soon
as a PPP frame is detected. But with "pl" set, a PPP login program
is started independently of the result of PPP detection (which is
rendered unnecessary then,) i.e. _unconditionally_.
because the run time exceeds the largest value a signed int can hold.
The real solution involves calculating how far we are over the limit.
To quickly solve this problem we loop removing 1/5th of the current value
until it falls below the limit. The common case requires no passes.
suggested by the version of the commit message that's mailed out
as opposed to the more error prone version that will be suggested
when doing the actual import.
- Emulate lock draining (LK_DRAIN) in null_lock() to avoid deadlocks
when the vnode is being recycled.
- Don't allow null_nodeget() to return a nullfs vnode from the wrong
mount when multiple nullfs's are mounted. It's unclear why these checks
were removed in null_subr.c 1.35, but they are definitely necessary.
Without the checks, trying to unmount a nullfs mount will erroneously
return EBUSY, and forcibly unmounting with -f will cause a panic.
- Bump LOG2_SIZEVNODE up to 8, since vnodes are >256 bytes now. The old
value (7) didn't cause any problems, but made the hash algorithm
suboptimal.
These changes fix nullfs enough that a parallel buildworld succeeds.

and run time.
- Scale the sleep and run time back via sched_interact_update() in more
places. This is to keep the statistic more accurate.
- Charge a parent one tick for forking a child.
- Add only the run time and not the sleep time to the parents kg when a
thread exits. This allows us to give a penalty for having an expensive
thread exit but does not give a bonus for having an interactive thread
exit.
- Change the SLP_RUN_THROTTLE to limit us to 4/5th and not 1/2.
- Change the SLP_RUN_MAX to two seconds. This keeps bursty interactive
applications like mozilla and openoffice in the interactive range even
through expensive tasks.
- Recalculate the slice after every sleep. This ensures that once a task
has been marked interactive it only has a slice of 1 at the risk of
giving tasks that sleep for a very brief period a longer time slice.
this makes connect act more sensibly in these cases.

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.

libstand/bootp.c may copy junk into the rest of the buffer, it was
possible for the code to find a ':' after the '\0' and do the wrong

are assumed from .? (any) files. This is not a problem in practice,
merely a bit untidy, as the linting rules DTRT. See the sys/conf/*
