Fixes Piglit test "swapbuffersmsc-return swap_interval 0".
Ensure that *swap_target gets initialized on any 'return Success' path,
even if the swap request can't be completed by the driver and the server
falls back to a simple blit. That path can also be triggered by setting
swap_interval to 0, which disables sync to vertical retrace.
We originally found this bug because for some reason SDL2 automatically
sets swap_interval to 0, when we were trying to test OML_sync_control in
an SDL2 test application. We then discovered that the above-mentioned
Piglit test has been failing for the same reason since it was
introduced.

swap_target is an out-parameter that needs to be set to the value that
SBC will take on after this SwapBuffers request completes.
However, it was also being used as a temporary variable to hold the MSC
at which the SwapBuffers request got scheduled to occur. This confusion
makes it harder to reason about whether swap_target is being set
correctly for its out-parameter usage. (Hint: It isn't.)
For the latter use, it makes more sense to use the existing target_msc
variable, which already has the right value unless target_msc, divisor,
and remainder are all 0, in which case we can set it using swap_interval
as usual.

This reverts commit 3209b094a3. After a
long debug session by Paul Berry, it appears that this was the commit
that has been producing sporadic failures in piglit front buffer
rendering tests for the last several years.
GetBuffers may return fresh buffers with invalid contents at a couple
reasonable times:
- When first asked for a non-fake-front buffer.
- When the drawable size is changed, an Invalidate has been sent, and
obviously the app needs to redraw the whole buffer.
- After a glXSwapBuffers(), GL allows the backbuffer to be undefined,
and an Invalidate was sent to tell the GL that it should grab these
appropriate new buffers to avoid stalling.
But with the patch being reverted, GetBuffers would also return fresh
invalid buffers when the drawable serial number changed, which is
approximately "whenever, for any reason". The app is not expecting
invalid buffer contents "whenever", nor is it valid. Because the GL
usually only GetBuffers after an Invalidate is sent, and the new
buffer allocation only happened during a GetBuffers, most apps saw no
problems. But apps that do (fake-)frontbuffer rendering do frequently
ask the server for the front buffer (since we drop the fake front
allocation when we're not doing front buffer rendering), and if the
drawable serial got bumped midway through a draw, the server would
pointlessly ditch the front *and* backbuffer full of important
drawing, resulting in bad rendering.
The patch was originally to fix bugzilla:
https://bugs.freedesktop.org/show_bug.cgi?id=28365
Specifically:
To reproduce, start with a large-ish display (i.e. 1680x1050 on my
laptop), use the patched glxgears from bug 28252 to add the
-override option. Then run glxgears -override -geometry 640x480
to create a 640x480 window in the top left corner, which will work
fine. Next, run xrandr -s 640x480 and watch the fireworks.
I've tested with an override-redirect glxgears, both with vblank sync
enabled and disabled, both with gnome-shell and no window manager at
all, before and after this patch. The only problem observed was that
before and after the revert, sometimes when alt-tabbing to kill my
gears after completing the test gnome-shell would get confused about
override-redirectness of the glxgears window (according to a log
message) and apparently not bother doing any further compositing.

This adds the initial prime support for dri2 offload. The main thing is
when we get a connection from a prime client, we stored the information
and mark all drawables from that client as prime. We then create all
buffers for that drawable on the prime device dri2screen.
Then DRI2UpdatePrime is provided which drivers can call to get a shared
pixmap which they can use as the front buffer. The driver is then
responsible for doing the back->front copy to the shared buffer.
prime requires a compositing manager be run, but it handles the case where
a window get un-redirected by allocating a new pixmap and pointing the crtc
at it while the client is in that state.
Currently prime can't handle pageflipping, so always does straight copy swap,

Since reallocating the backing pixmap can fail, we need to try and do
it before any other side effects of reconfiguring the window happen.
This changes the ConfigNotify hook to return status, and moves the
composite window reconfiguration wrappers to ConfigNotify. They all
basically did the same thing, so we can drop the MoveWindow,
ResizeWindow, ChangeBorderWidth wrappers, and allow ConfigNotify to do
all the work. If reallocation fails we fail before we send any
confiureNotify events, or enter the area we can't recover from.
The only place we now enforce 32k limits are in EXA/UXA/fb, so drivers
that don't use this should probably deal with it in their pixmap
allocate if they don't already.

Some drivers use DRI protocol but implement their own kernel rendering
manager. For these drivers, libdrm becomes useless. --disable-libdrm
configure parameter can be used to disable libdrm support in dri2.
To provide ABI/API compatibility for libdrm based drivers, libdrm call
is wrapped in ifdef.

This matches the test in TryClientEvents, and is a superset of tests
done by the callers of these functions. The consequence of forgetting
these tests is a server crash, so they're always desirable. In my
opinion, it's better to not require the callers to remember to do these
checks.
For callers that don't do very much work before calling WriteToClient or
WriteEventsToClient, I've removed the redundant checks.
hw/xquartz/xpr/appledri.c has an interesting case: While its check for
"client == NULL" appears redundant with the test in WriteEventsToClient,
it dereferences client to get the sequence number.

This lets the DRI2 clients rely on the server to notify them when they
need to get new buffers. Without this, OpenGL clients poll the server
in glViewport() which can be a performance problems and also isn't
completely correct behaviour.
We bump the DRI2 protocol minor to indicate the availability of the
event, which the DRI2 clients can use to avoid polling. This speeds up
various piglit and oglc test cases as well as real applications.

Some pixmaps (window pixmaps and scratch pixmaps) don't have the
drawable->id set and thus DRI2 gets confused when using that field
for looking up the DRI2 drawable. Go back to using privates for getting
at the DRI2 drawable from a DrawablePtr. We need to keep the resource
tracking in place so we can remove the DRI2 drawable when the X resource
it was created for goes away. Additionally, we also now track the DRI2
drawable using a client XID so we can reclaim the DRI2 drawable even if
the client goes before the drawable and doesn't destroy the DRI2 drawable.

The main motivation here is to have the resource system clean up the
DRI2 drawable automatically so glx doesn't have to. Right now, the
glx drawable resource must be destroyed before the X drawable, so that
calling DRI2DestroyDrawable doesn't crash. By making the DRI2
drawable a resource, GLX doesn't have to worry about that and the
resource destruction order becomes irrelevant.

Handle drawable destruction and lifetime correctly.
Check whether the drawable priv is valid in DRI2SwapInterval(),
DRI2WaitSBC() and DRI2WaitMSC(); it may have gone away, so be sure to
check it before using it.
If more than 1 outstanding swap is queued, we may complete several after
an app has exited. If we free it after the first one completes and the
refcount reaches 0, we'll crash the server on subsequent completions.
So delay freeing until all swaps complete and remove the error message
as this is a normal occurence. To do this properly, we must also avoid
destroying drawables in DRI2DestroyDrawable() if a swap or wait event is
pending.
And finally, make sure we free drawables in DRI2WaitMSCComplete() if
necessary (i.e. if the refcount has reached 0 and this MSC was the last
pending event on the object).

Fix for non-blocking case. Old implementation returned random,
uninitialized values for (ust,msc,sbc) if it returned immediately
without scheduling a wait due to sbc >= target_sbc.
Now if function doesn't schedule a wait, but returns immediately,
it returns the (ust,msc,sbc) of the most recently completed swap,
i.e., the UST and MSC corresponding to the time when the returned
current SBC was reached.
