kernel - rewrite the LWKT scheduler's priority mechanism
The purpose of these changes is to begin to address the issue of cpu-bound
kernel threads. For example, the crypto threads, or a HAMMER prune cycle
that operates entirely out of the buffer cache. These threads tend to hicup
the system, creating temporary lockups because they never switch away due
to their nature as kernel threads.
* Change the LWKT scheduler from a strict hard priority model to
a fair-share with hard priority queueing model.
A kernel thread will be queued with a hard priority, giving it dibs on
the cpu earlier if it has a higher priority. However, if the thread
runs past its fair-share quantum it will then become limited by that
quantum and other lower-priority threads will be allowed to run.
* Rewrite lwkt_yield() and lwkt_user_yield(), remove uio_yield().
Both yield functions are now very fast and can be called without
further timing conditionals, simplifying numerous callers.
lwkt_user_yield() now uses the fair-share quantum to determine when
to yield the cpu for a cpu-bound kernel thread.
* Implement the new yield in the crypto kernel threads, HAMMER, and
other places (many of which already used the old yield functions
which didn't work very well).
* lwkt_switch() now only round-robins after the fair share
quantum is exhausted. It does not necessarily always round robin.
* Separate the critical section count from td_pri. Add td_critcount.

HAMMER Utility - Add catastrophic recovery feature
* hammer -f <devices> recover <empty_target_dir>
* Add a catastrophic recovery feature. A HAMMER filesystem image is
scanned (using the -f <blockdevs> specification). Any buffer which
looks like a B-Tree node is then sub-scanned for inode, directory, and
data records and the filesystem is reconstructed in the specified
target directory.
* The files and directories are initially named after the object id
and are renamed and moved as directory entries are found to resolve
the fragmentory information.
* File writes strip trailing 0's (data records are not limited to the
file EOF), but will properly truncate the file if/when the related
inode record is found.
* Currently no attempt is made to restore owner, group, file modes,
softlinks, or hardlinks (only one link will be restored).
TODO: Currently a valid volume header is required, but the only thing
we actually need from it is the vol_buf_beg field. This field
could be guessed or passed in on the command line in a future
update to the recovery code.
