The cursor in DIX is actually split in two parts, the cursor itself and
the cursor bits, each with their own devPrivates.
The cursor itself includes the cursor bits, meaning that the cursor bits
devPrivates in within structure of the cursor.
Both Xephyr and Xwayland were using the private key for the cursor bits
to store the data for the cursor, and when using XSELINUX which comes
with its own special devPrivates, the data stored in that cursor bits'
devPrivates would interfere with the XSELINUX devPrivates data and the
SELINUX security ID would point to some other unrelated data, causing a
crash in the XSELINUX code when trying to (re)use the security ID.

Move the xcb_aux_sync into the shm path, where we do still need it to
synchronize access with the host. In the non-shm path the image is
copied to the host anyway so the sync just adds latency and keeps you
from using all your network bandwidth.
Only the non-shm-putimage path benefits from this, but the benefit is
significant even on the local machine (here a 3.2GHz Core i7-8700, using
XEPHYR_NO_SHM=1):

After a change for the xserver to automatically determine the seat
based on the XDG_SEAT variable, xephyr stopped working. This was
because of an old feature where xephyr used to handle evdev
directly. This was dropped some time ago, and now this check is
not needed
This is not actually a change for xwayland with gbm, or for xfree86 with
big-GL, but we do change them as well to use EGL_NO_CONFIG_KHR
explicitly.

There's no real benefit to using GLX, and the other DDXes are using EGL
already, so let's converge on EGL so we can concentrate the fixes in one
place.
We go to some effort to avoid being the thing that requires libX11 here.
We prefer EGL_EXT_platform_xcb over _x11, and if forced to use the
latter we'll ask the dynamic linker for XGetXCBConnection and
XOpenDisplay rather than link against xlib stuff ourselves. Xephyr is
now a pure XCB application if it can be.

The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.
Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.
v2: Update to match v2 of the vnd import, and remove more redundant work
like request length checks.

backend. (Kyle Brenneman)

hasn't been built yet. The unit tests are also not done.
The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools. meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.

The screen block and wakeup handlers are the only ones which provide a
well known ordering between the wrapping layers; placing these as
close as possible to the server blocking provides a way for the driver
to control the flow of execution correctly.
Switch the shadow code to run in the screen block handler so that it
now occurrs just before the server goes to sleep.
Switch glamor to call down to the driver after it has executed its own
block handler piece, in case the driver needs to perform additional
flushing work after glamor has called glFlush.
These changes ensure that the following modules update the screen in
the correct order:
animated cursors (uses RegisterBlockAndWakeupHandlers dynamically)
composite (dynamic wrapping)
misprite (dynamic wrapping)
shadow (static wrapping)
glamor (static wrapping)
driver (static wrapping)
It looks like there's still a bit of confusion between composite and
misprite; if composite updates after misprite, then it's possible
you'd exit the block handler chain with the cursor left hidden. To fix
that, misprite should be wrapping during ScreenInit time and not
unwrapping. And composite might as well join in that fun, just to make
things consistent.
[v2] Unwrap BlockHandler in shadowCloseScreen (ajax)
[v3] ephyr: Use screen block handler for flushing changes
ephyr needs to make sure it calls glXSwapBuffers after glamor finishes
its rendering. As the screen block handler is now called last, we have
to use that instead of a registered block/wakeup handler to make sure
the GL rendering is done before we copy it to the front buffer.
