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.

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.

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.

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).

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.

Add function vinum_mv, which moves subdisks to different drives. This
function just does the low-level configuration changes; the resultant
subdisk is stale if it previously had any contents, otherwise it is
empty (i.e. in need of initializing if it's RAID-5). We still need to
handle getting the contents moved over, but the current version will
suffice to migrate subdisks from a disk which has failed.
