Clean up svn:keywords property.
Fix for _INI regression introduced in version 20130328.

This change fixes a problem introduced in 20130328 where _INI methods
are no longer executed properly because of a memory block that is not
initialized correctly.

Pull in r181286 from upstream llvm trunk:

  LoopVectorize: getConsecutiveVector must respect signed arithmetic

  We were passing an i32 to ConstantInt::get where an i64 was needed and we must
  also pass the sign if we pass negatives numbers. The start index passed to
  getConsecutiveVector must also be signed.

  Should fix PR15882.

This should fix Firefox crashes some people have been reporting, when it
is compiled with -O3.
Bandaid for compiling with gcc, which happens to be the default compiler
for a number of platforms still.
The HPN patch added a new BUG bit for SSH_BUG_LARGEWINDOW
and the update to 6.1 added SSH_BUG_DYNAMIC_RPORT with the
same value.

Fix the HPN SSH_BUG_LARGEWINDOW bit so it is unique.

o Add accessor functions to add and remove pages from a specific
  freelist.
o Split the pool of free pages queues really by domain and not rely on
  definition of VM_RAW_NFREELIST.
o For MAXMEMDOM > 1, wrap the RR allocation logic into a specific
  function that is called when calculating the allocation domain.
  The RR counter is kept, currently, per-thread.
  In the future it is expected that such function evolves in a real
  policy decision referee, based on specific informations retrieved by
  per-thread and per-vm_object attributes.
o Add the concept of "probed domains" under the form of vm_ndomains.
  It is responsibility for every architecture willing to support multiple
  memory domains to correctly probe vm_ndomains along with mem_affinity
  segments attributes.  Those two values are supposed to remain always
  consistent.
  Please also note that vm_ndomains and td_dom_rr_idx are both int
  because segments already store domains as int.  Ideally u_int would
  have much more sense. Probabilly this should be cleaned up in the
  future.
o Apply RR domain selection also to vm_phys_zero_pages_idle().

Set st_nlink in the stat structure within the inode to 1 as well.
The cd9660 file system uses that field for the link count and it
was 0. This impacts pwd_mkdb(8) as it checks for st_nlink not being
0 as part of closing a race.
Begin tidying up the reassociation and node sleep/wakeup paths.

* Move the node sleep/wake state under the TX lock rather than the
  node lock.  Let's leave the node lock protecting rate control only
  for now.

* When reassociating, various state needs to be cleared.  For example,
  the aggregate session needs to be torn down, including any pending
  aggregation negotiation and BAR TX waiting.

* .. and we need to do a "cleanup" pass since frames in the hardware
  TX queue need to be transmitted.

Modify ath_tx_tid_cleanup() to be called with the TX lock held and push
frames into a completion list.  This allows for the cleanup to be
done atomically for all TIDs in a node rather than grabbing and
releasing the TX lock each time.
This lock only protects the rate control state for now, mention this.
Oops, commit the other half of r250606.
Since the node state is 100% back under the TX lock, just kill the use
of atomics.

I'll re-think this nonsense later.
Improve the debugging output - use the MAC address rather than various
pointer values everywhere.
As python3 does not have raw_input(), convert it to input() when we
are using python3.
