0c7a583f3a Add support for storing the priority mask in sched_whichqs in MSB order 
(enabled by defining __HAVE_BIGENDIAN_BITOPS in <machine/types.h>).  The
default is still LSB ordering.  This change will allow the powerpc MD
implementations of setrunqueue/remrunqueue to be nuked.

3ce3399c7b Add a dev_propdb to hold device properties. Properties are already being 
used in an ad hoc way by a couple of eval board ports, so might as well
tidy it up a little and add some formality.  (And, yes, I need to use it
in another eval board port.)

d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.

a06b275edc Undo part of the ktrace/lwp changes. In particular: 
* Remove the "lwp *" argument that was added to vget().  Turns out
  that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
  and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
  above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
  just to appease the above.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

998110e1d0 Put the tsleep() call in sa_yield() inside a while loop that tests 
whether there is anything to do - almost as if it were a predicate
test outside of a condition wait. This prevents returning to userland
when tsleep() has woken up spuriously, such as from a signal that was
caught and then removed by a tracing process.

Kills off some double-stops in GDB due to signals as well as a couple
of pthread__idle assertions when detaching from a process.

XXX stopping inside tsleep, via CURSIG(), is evil.

9d9a86120a Make ppsratecheck conform with its man page, which says, "If maxpps 
is set to 0, the function will always return 0 (no packets/events
are permitted)." Before this patch, ppsratecheck returned 1 once
a second when maxpps was 0.

15fab6425c Fix a variety of kernel panics related to unchecked export data: 
1. sa_len was not properly checked.
2. sa_family was not properly checked [even used as an array index!]
3. we only know about inet4 and inet6, so make sure that the corresponding
   data is valid before using it.
4. keep reference counts of addresses used (is that necessary?)
