Create/Destroy/Trigger/Reset/Query Fence Sync objs
Initial server side implementation of fence sync
objects. Allows creation, management, and state
queries of binary state objects. Currently they
are not very useful as there is no way to wait for
them efficiently.
The basic trigger operation added here triggers
relative to a given X screen's rendering operations.
To perform this operation, fence sync objects must
be tied to a screen. As Aaron Plattner pointed out,
screens are identified but a drawable in X protocol,
so a drawable argument is included in
XSyncCreateFence(). The screen also could have been
specified as part of the trigger operation. However,
it is also desireable to associate a screen with
fence sync objects at creation time so that the
associated screen's driver can allocate any HW-
specific resources needed by the fence object up
front.

Require xextproto 7.1.99
Subsequent changes rely on fence sync protocol
in the sync extension. This protocol is only
complete in xextproto version 7.1.99 and
above.

Add fence sync driver interface
-Add fence sync objects
-Add fence sync devPrivates
-Add a X sync module screen private
-Add wrappable functions to create and destroy
fence sync objects
-Give fence sync objects wrappable functions to
trigger, test, and reset their 'triggered' value.
-Give fence sync objects wrappable functions to
notify driver when adding/removing triggers to/
from the sync object.

commit af0f9f913398d34a885c3fb4e8d40c1a7e2b3ee9

Move some sync code to miext
As a precursor to the fence sync object video driver
and extension API, move some code from Xext to
miext/sync. Most of this is just code to set up the
build system to include the new directory. No
functional code is added in this change.

commit 12b65de7db6e3e8bf831914d247da269d01c5fbe
Author: James Jones <jajones at nvidia.com>

Factor out generic code from ProcSyncAwait()
In preparation for adding more sync object types
that will need Await requests of their own, factor
out some setup and finalization code from
ProcSyncAwait() into SyncAwaitPrologue() and
SyncAwaitEpilogue()

Make Await SyncTrigger functions generic
Update all the functions dealing with Await
sync triggers handle generic sync objects
instead of just counters. This will
facilitate code sharing between the counter
sync waits and the fence sync waits.

commit 99daf419a3070c347c0cd29b4a9bae07eca7bd6d
Author: James Jones <jajones at nvidia.com>
Date: Mon Jun 28 14:51:54 2010 -0700
Create SyncObject base type.
SyncObject is now the base type for SyncCounter.
Data to be used by all sync types is stored in
the base object. SyncCounter can be safely cast
to SyncObject, and a SyncObject can be cast to
the correct type based on SyncObject::type.

Add and use SERVER_SYNC_*_VERSION
Most extensions have a version defined
in the protocol headers, and also in the
server's protocol-versions.h. The latter
defines which version the server advertises
support for. Sync wasn't included in
protocol-versions.h, and was advertising
support for whatever was in the protocol
headers the server was built against.
