Setting glx_align64 to '' gives a null string in the arguments list passed
to the compiler. This is taken as an input filename, leading to:
"cc: error: : No such file or directory"
Instead, assign an empty list to glx_align64, which gets flattened to
nothing in the arguments list.

The extension was using the name CARD64 to represent 64-bit values,
with a #define from CARD64 to XSyncValue, a struct with a pair of
32-bit values representing a signed 64-bit value. This interfered
with protocol headers using CARD64 to try to actually store a
uint64_t. Now that stdint.h exists, let's just use that here,

UDL (usb) devices are blacklisted because of they weird behaviour when
it comes to vblank events. As EVDI uses very similar model of handling
vblanks it should be treated similarly.
When doing a page flip, EVDI does not wait for real vblank, but
simulates it by adding constant delay. It also does not support
DRM_IOCTL_WAIT_VBLANK.
In contrast to UDL, EVDI uses platform devices, thus instead of 'usb' in
path they all have 'platform'.
It is possible to blacklist by 'platform', so without explicitly saying
'evdi', but it might be misleading when it comes to real reason for it.

Calling xwl_window_from_window means looping through the window ancestor
chain whenever it is called on a child window or on an automatically
redirected window.
Since these properties and the potential ancestor's xwl_window are constant
between window realization and unrealization, we can omit the looping by
always putting the respective xwl_window in the Window's private field on
its realization. If the Window doesn't feature an xwl_window on its own,
it's the xwl_window of its first ancestor with one.

By having it as a custom_target with build_always, every "ninja -C

We could build the rest of Xorg into a static lib, and regenerate
date/time when the static lib changes and link that into a final Xorg,
but BUILD_DATE/TIME is such a dubious feature (compared to including a
git sha, which is easy with meson) it doesn't seem worth the build

... instead of its root window. Xwayland's rootless mode empties the
root window border clip since its root window has no storage, but
redirected windows (the only kind it can show) will have a non-empty
border clip anyway, cf. the #ifdef COMPOSITE in miComputeClips. With
this change, non-glamor Xwayland's GetImage actually works.
Other acceleration layers may need to change to account for this, but
this appears to be safe for the existing open source drivers. Only the
xfree86 DDX has any problem with losing its framebuffer on VT switch,
and even then only for UMS drivers (which excludes glamor, uxa, and sna
from consideration). This leaves exa, which already contains code to
evict pixmaps to host memory on VT switch. Since the xfree86 core will
still empty the root clip on VT switch, while the root window itself may
not contain a valid image we won't try to touch it, but GetImage from a
redirected window will now work even when switched away.

glamor_compute_transform_clipped_regions() uses a temporary box32
internally which is copied back to a box16 to init the regions16,
thus causing a potential overflow.
If an overflow occurs, the given region is invalid and the pixmap
init region will fail.
Simply check that the coordinates won't overflow when copying back to
the box16, avoiding a crash later down the line in glamor.

For the built in visuals, we'd typically select the "best" fbconfig
without considering the swap method. If the client then requests a
specific swap method, say GLX_SWAP_COPY_OML, it may well happen that the
first fbconfig matching requirements would have been paired with the 32-bit
compositing visual, and the client would render a potentially transparent
window.
Fix this so that we try to match fbconfigs with the same swap method to all
built-in visuals. That would guarantee that selecting a specific swap-
method would not influence the chance of getting a compositing visual.
