1 Move the debug.clock_adjust_* sysctls to debug.clock.adjust_* to
make it easier to get only the clock statistics.
2 Make the sysctls read-only [suggested by Marius].
3 When determining the new clock adjustment, we checked for an error
either larger than 12.5% or smaller than 12.5%. We left out an error
of exactly 12.5%. For errors larger than 12.5% we adjust the clock
reload value in such a way that the next clock interrupt would be
early (as in premature). For errors less than 12.5% we stopped the
adjustment.
The current algorithm doesn't benefit from excluding an error of
exactly 12.5%. Change the code to stop adjusting the clock if the
error is *not* larger than 12.5% [suggested by Marius].

o don't pre-assign key index to the global key table entries so device
has a chance to decide what to use
o make ieee80211_crypto_newkey take the desired flags as an argument
instead of wacking the key structure directly; this eliminates a
bunch of code warts
o add a new flag IEEE80211_KEY_GROUP to indicate a key is a WPA Group
key so devices don't need to guess (temporarily add this flag in the
ioctl code until we can get wpa_supplicant+hostapd updated)
o shuffle IEEE80211_KEY_* bits to move flags used internally to the high
nibble of the flags word

problems here, it became clear we were being too complex.
o Don't keep track of resources in two places
o Use resource_list_purge instead of rolling our own
o Just reassign the ownership of the resource, rather than freeing it
and reallocating it.
o Fix compile problems when sizeof(u_long) != sizeof(int)
attempt to clear its pending jobs list, as this could trigger another
signal, and cause an infinite recursion. What yppush_exit() tests
in order to determine whether to flush pending jobs is the
yppush_joblist chained list, so this is what needs to be cleared
in that case (not the yppush_jobs counter).

in BSD and MBR classes, ie. if provider below us uses the same metadata,
don't create labels based on the metadata.
This allows to create labels on geoms with rank != 1 without hacks.

o rid is stored in the resource, so don't bother keeping track of it here.
o Implement memory space
o Don't try to activate 'memory card' CFEs. This is type memory, as opposed
to the memory resource.
resource_list_find. Check to make sure that rle is not NULL and panic
if it is (but it appears that resource_list_add already panics, so I'm
not entirely sure it is necessary now).
Add a test to make sure we have a interrupt resource when we're
disabling it. This is also a cannot happen, but the extra care
shoudln't hurt.

whether or not the receive pipe is stopped. This ensures that we
do not attempt to start the same transfer twice, and it allows
ucomstop() to skip the restarting of the read pipe if it was not
originally running, such as when called indirectly from ucomreadcb().

be made per filesystem if we had any filesystems which differed from
ffs in locking guarantees. VFS itself is not sensitive to this except
where vgone() etc. are concerned.

potential lock order reversal. Also, don't unlock the vnode if this
fails, lockmgr has already unlocked it for us.
- Restructure vget() now that vn_lock() does all of VI_DOOMED checking
for us and also handles the case where there is no real lock type.
- If VI_OWEINACT is set, we need to upgrade the lock request to EXCLUSIVE
so that we can call inactive. It's not legal to vget a vnode that hasn't
had INACTIVE called yet.

as I'd like to get rid of the vxthread.
- Handle lock requests which don't actually want a lock as this is a
much more convenient place to handle this condition than in vget().
These requests simply want to know that VI_DOOMED isn't set.
- Correct a test at the end of vn_lock, if error !=0 should be
if error == 0, this has been broken since I comitted the VI_DOOMED
changes, but no one ran into it because vget() duplicated this
functionality.
