Once the Barnes-Hut tree is constructed, the gravitational
force calculations can be done in parallel by dividing the
bodies up between a number of procs.
on thinkpad x1v4, the PCMP structure resides in upper reserved memory
pa=0xd7f49000 - while system memory ends at 0x0ffff000; so we have to
vmap() it instead of KADDR().
the RSD structure for ACPI might reside in low memory, so we sould
KADDR() in that case.

- simplify doauth, use error string for auth_getuserpasswd() error logging
- enable #pragma varargck for dBprint()
The Plan 9 assemblers use strtoll to parse the integer literals
in their input. It turns out that this is almost correct, but
VLONG_MIN is clamped. This patch changes to use strtoull
in order to allow the full range of integers.
The plan 9 assemblers support the DUPOK flag on text symbols. They parse and
ignore it on GLOBL symbols. This patch makes it work in the linkers.
The reason I ran into this is because my programming language (Myrddin) uses
data symbols to generate type information, and it's useful to avoid
duplicating all of the type info in every file that gets generated.
devmouse controls the screen blanking timeout, so move the
code there avoiding cross calls between modules. the only
function that needs to be provided is blankscreen(), which
gets called with drawlock locked.
the blank timeout is set thru /dev/mousectl now, so kernels
without devvga can set it.
blanking now only happens while /dev/mouse is read. so this
avoids accidentally blanking the screen on cpu servers that
do not have a mouse to unblank it.
now that locking works, its time to get rid of it.
given that the only concurrency is between the periodic reader
process and the filesystem code, just make sure the filesystem
rpc handlers do not run concurrenty while syncing is in progress
with a single qlock.
Zooming when far away from the center of gravity
of the galaxy would zoom the center of the screen
out of view. Now adjust the origin so that the
center of the screen stays centered
