The cleaner is compiled into rump_lfs and executed as a thread. Pass
in the raw device using the new -J option. This avoids the use of
getdiskrawname which is not particularly rump safe in this context and
insures that the rump container device is used for cleaning, not the
outer device.

Use the lfs header file and lfs's mount args struct, not ufsmount.h
and the ffs mount args struct, for mounting lfs.

(they are the same, so this doesn't matter yet, but still...)

After mount_lfs_parseargs, reset getopt for lfs_cleaner_main.

Give usage() a chance.
XXX: UKFS_DEVICE_ARGVPROBE() interface

Make r/w servers unmount themselves cleanly upon receiving SIGINT/TERM.

Call ukfs_part_release(). For completeness and educational value.

Adapt ukfs users to the new ukfs_part interface.

Link fs components into binary instead of loading dynamically now
that it's possible (dependency handling changes to rumpuser_dl).

Need to p2k_init() (i.e. fork()) earlier to not lose threads created
in rump_init().

adapt to new p2k interfaces

Adjust names of external rump control interfaces to match the
new rump_pub namespace.

Start cleaner without the sleep(1) hack now that it's possible.

Support disklabels.

run lfs cleaner

don't need absolute paths for fs component names

Make rump_lfs work again: load fs components dynamically instead
of trying to link them in on the command line and get pounded by
link set failage.

branches: 1.3.2;
adjust copyright to match reality. no functional change.

Refactor mount utilities to provide a mount_fs_parseargs() routine.
Use this routine both in mount_fs and rump_fs to provide equivalent
command line parameters and therefore usage interchangeability.
While doing this, combine some common mountgoop to mountprog.h

Install rump libraries and utilities to the base system and remove the
private non-installed build infrastructure from sys/rump.

breakdown of commit:
* install relevant headers into /usr/include/rump
* build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern
from src/lib and install as librumpuser and librump, respectively
+ this retains the ability to test a librump build with just the
kernel sources at hand
* move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib
for general consumption, they are not kernel-space dwellers anyway
* build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs
* add chapter 3 manual pages for rump, rumpuser, ukfs and p2k
* build and install userspace kernel file system daemons if MKPUFFS=yes
is spexified
* retire fsconsole for now, it will make a comeback with an actually
implemented version shortly
