Add better color matching selecting free pages. KM pages will now allocated

When allocating kernel memory pages, allow the MD to specify a preferred

of memory (> 4GB), all kernel memory to come from <4GB to reduce the amount
of bounce buffering needed with 32bit DMA devices.

Introduce struct pathbuf. This is an abstraction to hold a pathname
...
and the metadata required to interpret it. Callers of namei must now
create a pathbuf and pass it to NDINIT (instead of a string and a
uio_seg), then destroy the pathbuf after the namei session is
complete.
Update all namei call sites accordingly. Add a pathbuf(9) man page and
update namei(9).
The pathbuf interface also now appears in a couple of related
additional places that were passing string/uio_seg pairs that were
later fed into NDINIT. Update other call sites accordingly.

Be a little more friendly to dynamic physical segment registration.
...
Maintain an array of pointer to struct vm_physseg, instead of struct
array. So that VM subsystem can take its pointer safely. Pointer

only low-layer VM and MD code.
