Implement two previously-reserved Capsicum system calls:
- cap_new() creates a capability to wrap an existing file descriptor
- cap_getrights() queries the rights mask of a capability.

(typically fsck_ffs) to register that it wishes to use FFS specific
sysctl's to update the filesystem. This ensures that two checkers
cannot run on a given filesystem at the same time and that no other
process accidentally or maliciously uses the filesystem updating
sysctls inappropriately. This functionality is needed by the
journaling soft-updates recovery code.
Code to actually implement Capsicum capabilities, including fileops and
kern_capwrap(), which creates a capability to wrap an existing file
descriptor.
We also modify kern_close() and closef() to handle capabilities.
Finally, remove cap_filelist from struct capability, since we don't
actually need it.

As Garrett points out,
It is no more a debugging interface than setproctitle(3), and has not
been since the name started getting stuffed into the kernel. This
statement may have made sense when the name was only visible in thread
state dumps and the debugger.

flag (FS_SUJ) when determining whether to do journaling-based
operations. The mount flag is set only when journaling is active
while the superblock flag is set to indicate that journaling is to
be used. For example, when the filesystem is mounted read-only, the
journaling may be present (FS_SUJ) but not active (MNTK_SUJ).
Inappropriate checking of the FS_SUJ flag was causing some
journaling actions to be attempted at inappropriate times.

to announce driver specific offload capabilities to upper stack,
checksum offloading support needs more work and will be done in
future.

For the curious:
There's been many revisions to the Japan regulatory rules.
Apparently, the requirements require old cards certified on a previous
version of the rules to obey the older rules, not the newer rules.
The regdomain.xml outlines the -current- restrictions.
The card driver (eg the ath_hal regulatory domain code) may include
previous revisions of the Japan rules.
The ath_hal regdomain code populates the initial channel list based on
what the EEPROM indicates is possible. The regdomain.xml database imposes
further restrictions on this.
So regdomain.xml only needs to have the -current- rules. If the card
was certified on an earlier set of JP rules, it may only support a subset
of those channels - these are calculated at device attach and this
restricted list is kicked to net80211. regdomain.xml operates on -this-
list of channels.
And thus, the correct regulatory behaviour for Japan is handled with only
one regdomain.xml Japan database entry.

causes infinite hang in this regard. The fix is to use mi_switch() instead of
pause() to do the required task switch to ensure that the required USB processes
get executed.

r179247 introduced a possibility of devfs_allocv() returning spurious
ENOENT. If the vnode is selected by vnlru daemon for reclamation, then
devfs_allocv() can get ENOENT from vget() due to devfs_close() dropping
vnode lock around the call to cdevsw d_close method.
Use LK_RETRY in the vget() call, and do some part of the devfs_reclaim()
work in devfs_allocv(), clearing vp->v_data and de->de_vnode. Retry the
allocation of the vnode, now with de->de_vnode == NULL.
The check vp->v_data == NULL at the start of devfs_close() cannot be
affected by the change, since vnode lock must be held while VI_DOOMED
is set, and only dropped after the check.
