of a fix for the recently reported hangs.

work because it referred to plexes which were almost invariably when
referred to. Instead, deprecate the "prefer" keyword for volumes
(though it's still there for the moment) and add a keyword "preferred"
to the plex definition. The relationship is like this:
Old:
vol foo ... prefer foo.p3
New:
plex foo.p3 volume foo preferred
printconfig: Print out the "preferred" keyword for plexes where
appropriate.
Still print out "prefer" for volumes. The kernel module
continues to accept this version, but it's probably not
going to live much longer.
vinum_read:
Accept 0 parameters, hand an empty string to the kernel if so.
Use new ioctl VINUM_READCONFIG, not VINUM_CREATE, to read config.
vinum_start: When passed 0 parameters, drop the devstat kludge and
call vinum_read instead. It's no longer necessary to distinguish
between "start" and "read" if no parameters are passed, and
probably one of them should go away.
Change name of history file to History to avoid name conflicts.
Don't try to make devices unless devfs has been removed.
Don't accept resetconfig command from a file.

Rewrite minor number decoding. Now we have only three types of
object: subdisks, plexes and volumes. The encoding for plexes and
subdisks no longer reflects the object to which they belong. The
super devices are high-order volume numbers. This gives vastly more
potential volumes (4 million instead of 256).
Don't try to chown directories if they haven't been created.

This is the non-DEVFS part which is normally not used in 5.x, but due
for MFC into 4.x.

1.) prefix all functions in the library with devstat_ (compatability
functions are available for all functions that were chaned in an
incompatible way, but are deprecated).
2.) Add a pointer to a kvm_t as the first argument to functions that
used to get their information via sysctl; they behave the same
as before when NULL is passed as this argument, otherwise, the
information is obtained via libkvm using the supplied handle.
3.) Add a new function, devstat_compute_statistics(), that is intended
to replace the old compute_stats() function. It offers more
statistics data, and has a more flexible interface.
libdevstat does now require libkvm; a library depedency is added, so
that libkvm only needs to be explicitely specified for statically linked
programs.
The library major version number is bumped.

Remove the gross debug device/non-debug device hack used to recognize
whether the kernel module was in sync with the userland module.
