Fix buildworld for powerpc.

vmpage requires struct pmap to exist and contain a pm_stats field. As of
r308817, either AIM or BOOKE is required to be set in order to get their
respective pmap structs. Rather than expose them both, or try to unify them
unnecessarily, add a third option which contains only a pm_stats field, and
change the two existing pmap structures to place the common fields at the
beginning of the struct. This actually fixes the stats collection by libkvm on
AIM hardware, because before it was accessing a possibly different offset, which
would cause it to read garbage.

Bump __FreeBSD_version to denote this ABI change, so that ports which depend on
libkvm can be rebuilt.

Teach umastat about the variable-length array of per-CPU caches at the end
of struct uma_zone. It is declared as an array of size [1], but then
sized at run-time by UMA to include room for mp_maxid+1 CPUs. We have to
copy the uma_zone first at the declared structure size, then check to make
sure it's not an internal zone before copying the larger size (UMA
internal zones don't use per-CPU caches). This fixes umastat for SMP.

Add a simple KVM tool to dump the kernel state of UMA, including walking

Add a simple KVM tool to dump the kernel state of UMA, including walking
the keg/zone lists, summarizing cache state, and walking bucket lists in
each zone. I seem to get inconsistent results on SMP, possibly due to
local header problems, but it seems to work quite well on UP. This tool
requires sufficient privilege to read /dev/mem (or a core dump), and is
for debugging purposes rather than administrative monitoring purposes
(use vmstat instead).
