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.

This commit is the first of a general cleanup of the header files..
It won't be enough to make bde happy.
Remove vinum_perror and associated DEVBUG definition.
Use userland expurgated versions of kernel structures, since that's
what the ioctls return now.
Remove vinum_perror.
main: Check kernel version with userland version in _vinum_conf. This
field is a constant which gets incremented every time the
kernel-userland interface changes. This enables vinum(8) to
check for the correct kernel version and to produce a useful
message if it doesn't match. For previous versions, which don't
have a version number, the length of the structure is different,
so we can recognize it via the EINVAL return from ioctl.
Supply count parameter to tokenize().
Change method of recognizing active devfs: replace devfs_is_active
with (complemented) no_devfs.
make_devices: remove references to devfs. If we're running devfs, we
don't need to call make_devices at all.
vinum_makedev (user command 'makedev'): Print a warning message if
devfs is running and don't do anything else.
Remove vinum_perror.
Modify 'list' brief printout to fit in 80 columns.
Modify 'ls' brief printout to show the drive to which the subdisk
before instead of the plex offset, which is usually less interesting.
The verbose printout remains unchanged.
Use userland expurgated versions of kernel structures, since that's

Move checkupdates here to simplify header file mess.
Remove 'vinum_perror'.
Only call make_devices if we're not running devfs.
Use userland expurgated versions of kernel structures, since that's

Update help list, which was lagging behind reality.
checkupdates: move to list.c to simplify header file mess.
vinum_stripe, vinum_mirror, vinum_raid4, vinum_raid5: change the
default stripe size from 256 k to 279 k, thus hopefully spreading
superblocks more evenly.
userland tool:
Use the vfs.devfs.generation sysctl to test for devfs presense
(thanks phk!) when devfs is active it will not try to create the
device nodes in /dev and therefore will not complain about the
failure to do so.
Revert the change in the #define for VINUM_DIR in the kernel
header so that vinum can find its device nodes.
Replace perror() with vinum_perror() to print file/line when
DEVBUG is defined (not defined by default).
kernel:
Don't use the #define names for the "superdev" creation since
they will be prepended by "/dev/" (based on VINUM_DIR), instead
use string constants.
Create both debug and non-debug "superdev" nodes in the devfs.
