If the underlying X11 window gets destroyed, the event we're waiting
for may never be delivered, in which case xcb_wait_for_special_event
would hang indefinitely.
Solution:
1. Use xcb_poll_for_special_event to check if an event has arrived yet.
2. If not, Wait up to ~1s for XCB's file descriptor to become readable;
if it does, go back to step 1.
3. If the file descriptor didn't become readable, make a round-trip to
the X server to check that the window still exists. Go back to step
1 if it does, otherwise bail.
Also add an early bail-out when it's known that the window was
destroyed.

Before, if one thread ended up waiting in dri3_wait_for_event_locked
and another one in loader_dri3_wait_for_msc at the same time, one thread
could end up processing an event the other thread was waiting for, which
could result in the latter thread waiting longer than necessary
(possibly indefinitely).

Currently, if the PCI machinery fails, we return a NULL driver name.
In the past this has resulted in various workarounds.
To avoid those, fallback to loader_get_kernel_driver_name(). It's not

This is definitely not the first time I've debugged why I'm getting swrast
on a device only to find out I'm not a member of the render node's group.
This does mean that you'll get a warning print even without EGL_LOG_LEVEL
set. This may be an issue if we expect people outside of the DRI node's
group to actually be using swrast instead of getting their permissions
fixed. Right now surfaceless throws a "libEGL warning: No hardware driver

Enabling this option makes Intel Gen8-11 hardware load the 'iris'
driver by default instead of the older 'i965' driver.
Regardless of how this option is set, users can still override which
driver the loader selects via two methods. The first is to create a
~/.drirc or /etc/drirc file with the following snippet:
<driconf>
<device driver="loader" kernel_driver="i915">
<option name="dri_driver" value="i965" />
</device>
</driconf>
The other option is to set an environment variable:
export MESA_LOADER_DRIVER_OVERRIDE=i965
For now, "prefer_iris" defaults to i965 (the historical choice).
A separate future patch will change the default driver to iris.

The DDX driver can be notified of adaptive sync suitability by
flagging the application's window with the _VARIABLE_REFRESH property.
This property is set on the first swap the application performs
when adaptive_sync is set to true in the drirc.
It's performed here instead of when the loader is initialized for
two reasons:
(1) The window's drawable can be missing during loader init.
This can be observed during the Unigine Superposition benchmark.
(2) Adaptive sync will only be enabled closer to when the application
actually begins rendering.
If adaptive_sync is false then the _VARIABLE_REFRESH property
is deleted on loader init.
The property is only managed on the glx DRI3 backend for now. This
should cover most common applications and games on modern hardware.
Vulkan support can be implemented in a similar manner but would likely
require splitting the function out into a common helper function.
