ec5a93183a merge yamt-uio_vmspace branch. 
- use vmspace rather than proc or lwp where appropriate.
  the latter is more natural to specify an address space.
  (and less likely to be abused for random purposes.)
- fix a swdmover race.

2d1a0b57b6 kill the "fault_type" argument to pager's pgo_fault() methods 
it is never used
(and using it would comprise an abstraction violation imho)

ed2f09f139 Add a "show all pages" command to DDB which prints one line per physical 
page in the system.  Useful for getting some idea where all your memory's
gone, at least on a sufficiently small system.

fbae48b901 Change "inline" back to "__inline" in .h files -- C99 is still too 
new, and some apps compile things in C89 mode. C89 keywords stay.

da3f825c26 remove the assertion in uvm_swapout_threads() about LSONPROC lwps 
not running on the same CPU as the swapper.  l_stat is protected by
sched_lock, which isn't held here, so we can race with that lwp
starting to run and see its l_cpu not updated yet, as in PR 31870.
we check l_stat again in uvm_swapout() while holding sched_lock,
so the race itself is harmless.

aec75b1cc6 - change the way to specify a bufq strategy. (by string rather than by number) 
- rather than embedding bufq_state in driver softc,
  have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
  from sys/bufq.h to sys/bufq_impl.h.
  (is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c.  (not tested)
