Enhance Makefile.inc processing, when asked for, to include the most
specific (MACHINE specific) to least specific (MACHINE_CPUARCH).

Introduce MACHINE_CPUARCH. Many different MACHINE_ARCHs will be built
from one MACHINE_CPUARCH. This will allow us to move to a more
standard MACHINE_ARCH for mips and arm which exist in many different
endian variants, and for powerpc where both 32 and 64 bit binaries are
generated from the same sources.

802.11 duplicate detection. Upon looking at the standard, we discover
that 802.11-2007 says:
"A receiving QoS STA is also required to keep only the most recent
cache entry per<Address 2, TID, sequence-number> triple, storing only
the most recently received fragment number for that triple. A receiving
STA may omit tuples obtained from broadcast/multicast or ATIM frames
from the cache."
To fix this, we just disable duplicate detection for multicast/broadcast
frames.

PG_REFERENCED changes in vm_pageout_object_deactivate_pages().
Simplify this function's inner loop using TAILQ_FOREACH(), and shorten
some of its overly long lines. Update a stale comment.
Assert that PG_REFERENCED may be cleared only if the object containing
the page is locked. Add a comment documenting this.
Assert that a caller to vm_page_requeue() holds the page queues lock,
and assert that the page is on a page queue.
Push down the page queues lock into pmap_ts_referenced() and
pmap_page_exists_quick(). (As of now, there are no longer any pmap
functions that expect to be called with the page queues lock held.)
Neither pmap_ts_referenced() nor pmap_page_exists_quick() should ever
be passed an unmanaged page. Assert this rather than returning "0"
and "FALSE" respectively.
ARM:
Simplify pmap_page_exists_quick() by switching to TAILQ_FOREACH().
Push down the page queues lock inside of pmap_clearbit(), simplifying
pmap_clear_modify(), pmap_clear_reference(), and pmap_remove_write().
Additionally, this allows for avoiding the acquisition of the page
queues lock in some cases.
PowerPC/AIM:
moea*_page_exits_quick() and moea*_page_wired_mappings() will never be
called before pmap initialization is complete. Therefore, the check
for moea_initialized can be eliminated.
Push down the page queues lock inside of moea*_clear_bit(),
simplifying moea*_clear_modify() and moea*_clear_reference().
The last parameter to moea*_clear_bit() is never used. Eliminate it.
PowerPC/BookE:
Simplify mmu_booke_page_exists_quick()'s control flow.

Even though Roman removed these directories in his working copy, they
weren't removed from the actual repository, also causing his working
copy to be corrupted.
sctp_inpcb:
1) Make sure not to remove the flag on the PCB until
after the close() caller is back in control with the
lock. Otherwise a quickly freeing assoc could kill the
inpcb and cause a panic.
2) Make sure all calls to log_closing have not released
the locks before calling the log function, we don't
want the logging function to crash us due to a freed
inpcb.
3) Make sure that when we get to the end, we release all
locks (after removing them from view) and as long as
we are NOT the inp-kill timer removing the inp, call
the callout_drain() function so a racing timer won't
later call in and cause a racing crash.
