We don't need to wait before drawing to the fake front buffer, as front
buffer rendering by definition is allowed to produce artifacts.

Detect if the display (X-Server) gpu and Prime renderoffload gpu prefer
different channel ordering for color depth 30 formats ([X/A]BGR2101010
vs. [X/A]RGB2101010) and perform format conversion during the blitImage()
detiling op from tiled backbuffer -> linear buffer.
For this we need to find the visual (= red channel mask) for the
X-Drawable used to display on the server gpu. We use the same proven
logic for finding that visual as in commit "egl/x11: Handle both depth
30 formats for eglCreateImage()".
This is mostly to allow "NVidia Optimus" at depth 30, as Intel/AMD
gpu's prefer xRGB2101010 ordering, whereas NVidia gpu's prefer
xBGR2101010 ordering, so we can offload to nouveau without getting
funky colors.
Tested on Intel single gpu, NVidia single gpu, Intel + NVidia prime
offload with DRI3/Present.
Note: An unintended but pleasant surprise of this patch is that it also
seems to make the modesetting-ddx of server 1.20.0 work at depth 30
on nouveau, at least with unredirected "classic" X rendering, and
with redirected desktop compositing under XRender accel, and with OpenGL
compositing under GLX. Only X11 compositing via OpenGL + EGL still gives
funky colors. modesetting-ddx + glamor are not yet ready to deal with
nouveau's ABGR2101010 format, and treat it as ARGB2101010, also exposing
X-visuals with ARGB2101010 style channel masks. Seems somehow this triggers
the logic in this patch on modesetting-ddx + depth 30 + DRI3 buffer sharing
and does the "wrong" channel swizzling that then cancels out the "wrong"
swizzling of glamor and we end up with the proper pixel formatting in
the scanout buffer :). This so far tested on a NVA5 Tesla card under KDE5
Plasma as shipping with Ubuntu 16.04.4 LTS.

may already be using higher sequence numbers than us. In that case, we
could stop processing after an event from another client, which could
have been received significantly earlier. This would have multiple
undesirable effects:
* The computed MSC and UST values would be lower than they should be
* We could leave a growing number of NotifyMSC events from ourselves and
other clients in XCB's special event queue
I ran into this with Firefox and Thunderbird, whose VSync threads both
seem to use the same window. The result was sluggish screen updates and
growing memory consumption in one of them.

Upon reception of an event that lowered the number of active back buffers,
the code would immediately try to free all back buffers with an id equal to or

However, that could lead to an active or to-be-active back buffer being freed,
since the old number of back buffers was used when obtaining an idle back
buffer for use.
This lead to crashes when lowering the number of active back buffers by
transitioning from page-flipping to non-page-flipping presents.
Fix this by computing the number of active back buffers only when trying to
obtain a new back buffer.

It turned out that with recent changes that call into dri3 from glFinish(),
it appears like different thread end up waiting for X events simultaneously,
causing deadlocks since they steal events from eachoter and update the dri3
counters behind eachothers backs.
This patch intends to improve on that. It allows at most one thread at a
time to wait on events for a single drawable. If another thread intends to
do the same, it's put to sleep until the first thread finishes waiting, and
then it rechecks counters and optionally retries the waiting. Threads that
poll for X events never pulls X events off the event queue if there are
other threads waiting for events on that drawable. Counters in the
dri3 drawable structure are protected by a mutex. Finally, the mutex we
introduce is never held while waiting for the X server to avoid
unnecessary stalls.
This does not make dri3 drawables completely thread-safe but at least it's a
first step.

EGL uses the force_copy parameter to loader_dri3_swap_buffers_msc() to indicate
that it wants to preserve back buffer contents across a buffer swap.
While the loader then turns off server-side page-flipping there's nothing to
guarantee that a new backbuffer isn't chosen when EGL starts to render again,
and that buffer's content is of course undefined.
So rework the functionality:
If the client supports local blits, allow server-side page flipping and when
a new back is grabbed, if needed, blit the old back's content to the new back.
If the client doesn't support local blits, disallow server-side page-flipping
to avoid a client deadlock and then, when grabbing a new back buffer, sleep
until the old back is idle, which may take a substantial time depending on
swap interval.

Always use 3 buffers when flipping. With only 2 buffers, we have to wait
for a flip to complete (which takes non-0 time even with asynchronous
flips) before we can start working on the next frame. We were previously
only using 2 buffers for flipping if the X server supports asynchronous
flips, even when we're not using asynchronous flips. This could result
in bad performance (the referenced bug report is an extreme case, where
the inter-frame stalls were preventing the GPU from reaching its maximum
clocks).
I couldn't measure any performance boost using 4 buffers with flipping.
Performance actually seemed to go down slightly, but that might have
been just noise.
Without flipping, a single back buffer is enough for swap interval 0,
but we need to use 2 back buffers when the swap interval is non-0,
otherwise we have to wait for the swap interval to pass before we can
start working on the next frame. This condition was previously reversed.
