[PATCH xserver (v4) 00/10] X Server support for Fence Sync

In v4: Completely reorganized patch basedo on Keith Packard's
feedback.  End result is almost identical, but the road there
is very different.

I've prepended a patch to add SERVER_SYNC_*_VERSION
to the whole series.  That this was previously missing
makes the re-organization less useful, since these
patches won't apply retroactively to older servers
built against new protocol headers, but I've added this
hoping it will help in the future.  This first patch
may be a candidate for back-porting to stable server
branches as well.

Implements X Sync Fence Objects in the server, including
the damage 1.2 support for DamageSubtractAndTrigger.  Re-
uses X Sync Counter code wherever possible.  A driver
interface has also been added so DDX drivers can redirect
fence sync operations to HW rendering backend operations.

James Jones (10):
  Add and use SERVER_SYNC_*_VERSION
  Create SyncObject base type.
  Make Await SyncTrigger functions generic
  Factor out generic code from ProcSyncAwait()
  Move some sync code to miext
  Add fence sync driver interface
  Require xextproto 7.1.99
  Create/Destroy/Trigger/Reset/Query Fence Sync objs
  Add XSyncAwaitFence() handler
  Expose Sync Fence Object protocol
