shouldn't release resources. As a quick hack to prevent double
frees etc, introduce "dead" variable into fuse channel to signal
if the backing puffs resource was already freed. XXX: the check
is only in exit/unmount currently.
Proper fix really depends on some puffs features I still haven't
gotten around to doing.
- remove cpu_exit.9.
- remove ctxsw.9 from makefile because it's too stale.
XXX maybe it will revive as mi_switch.9 later.
- add cpu_switchto.9 to makefile.

idle lwp, and some changes depending on it.
1. separate context switching and thread scheduling.
(cf. gmcgarry_ctxsw)
2. implement idle lwp.
3. clean up related MD/MI interfaces.
4. make scheduler(s) modular.
Introduce a parameter -r to control the root node type. For example
"dtfs -r 'lnk /etc' /puffs" mounts dtfs with the root node as a
symbolic link to /etc:
jojonaru# ./dtfs -r 'lnk /etc' /puffs
jojonaru# ls -l /puffs
lrw-rw-rw- 1 root wheel 4 May 17 14:06 /puffs -> /etc
jojonaru# cd /puffs
jojonaru# pwd
/etc
jojonaru#
Extra credit for figuring out how to unmount this file system with
umount(8).
Likewise, "dtfs -r 'chr 2 12' /puffs" makes /puffs (i386) /dev/zero etcetc.
instead of puffs_start(). Get completely rid of puffs_start(), as
everything it used to do is now handled by the mount routine.
Introduce an optional pre-mount call puffs_setrootinfo() for setting
non-default root node information. As the old puffs_mount() is
now virtually useless, say byebye to it and rename the old
puffs_domount() to puffs_mount(), but add a root cookie parameter
to compensate for the late puffs_start().
and other information instead of always using VDIR. To make this
possible without races, require all root node information already
in puffs_mount() and nuke puffs_start2() and the associated start
operation completely.

- make sure argc is initialized and argv is set to NULL after freeing.
- make the deep copy function an opt interface function.

- Use malloc and free instead of macros, delete macros.
- Merge the two copies of deep copy and free args that were slightly buggy
into one and use that one.

Provide a default for FUSE_USE_VERSION if it's not set, and use this
value to determine the number of arguments given to fuse_main().
