GetTimeInMillis is called first, which sets clockid to

the callers of GetTimeInMicros want.
Prior to a779fda224, GetTimeInMillis and

Instead of testing window->redirectDraw.
With Xwayland, the toplevel window is always redirected, so this would
unnecessarily preclude flipping there in some cases, e.g. with wlroots
based Wayland compositors or with fullscreen X11 windows in weston.
Fixes issue #631.
The VGA arbiter controls the PCI bus' routing of legacy VGA resources,
specifically the video memory aperture at 0xa0000-0xb0000 (640k should
be etc.) and a handful of I/O ports. Since 128k is far too small for a
real framebuffer these days, every driver instead maps a linear version
of VRAM through the PCI BAR. And no DRI2 drivers ever need I/O port
access, because all operations they might be used for (legacy VGA CRTC
setup, mostly) happen on the kernel side.
In other words, this just works, and we can stop breaking it.

A user of Adélie Linux reported that modesetting wasn't working properly on
their Intel i7-9700K-integrated UHD 630 GPU. Xorg.0.log showed:
[ 131.902] (EE) modeset(0): [DRI2] No driver mapping found for PCI device 0x8086 / 0x3e98
[ 131.902] (EE) modeset(0): Failed to initialize the DRI2 extension.
Indeed, that PCI ID is missing from i965_pci_ids. Adding it fixed the issue
and allowed the system to work with i965_dri under modesetting.
Both because extension names are inconsistently capitalized on the wire,
and because the table we're walking spells it COMPOSITE not Composite.
The latter is certainly also a bug, but there's no reason for us to be
that strict.

If the driver calls xf86HandleColormaps, CMapChangeGamma updates the HW
gamma LUT of all CRTCs via xf86RandR12LoadPalette. However,
xf86RandR12ChangeGamma was then clobbering the gamma LUT of the RandR
1.2 compatibility output's CRTC with the gamma curves computed from the
screen's global gamma values.
Fix this by bailing if xf86RandR12LoadPalette is installed.

Xwayland creates and destroys the CRTC along with the Wayland outputs,
so there is possibly a case where the number of CRTC drops to 0.
However, `xwl_present_get_crtc()` always return `crtcs[0]` which is
invalid when `numCrtcs` is 0.
That leads to crash if a client queries the Present capabilities when
there is no CRTC, the backtrace looks like:
#0 raise() from libc.so
#1 abort() from libc.so
#2 OsAbort() at utils.c:1350
#3 AbortServer() at log.c:879
#4 FatalError() at log.c:1017
#5 OsSigHandler() at osinit.c:156
#6 OsSigHandler() at osinit.c:110
#7 <signal handler called>
#8 main_arena() from libc.so
#9 proc_present_query_capabilities() at present_request.c:236
#10 Dispatch() at dispatch.c:478
#11 dix_main() at main.c:276
To avoid returning an invalid pointer (`crtcs[0]`) in that case, simply
check for `numCrtcs` being 0 and return `NULL` in that case.
Thanks to Michel Dänzer <michel.daenzer@amd.com> for pointing this as a
possible cause of the crash.

This removes the dependency on an externally generated docker image, and

But it should be easy to base it on another distro.

Gitlab very kindly exposes the details of the git commit message (among
much else) in the environment. Unfortunately, piglit tries to handle the
environment in non-UTF8-safe ways, which means if the top-of-tree commit
mentions non-ASCII characters (say, in the author's name) then all the
tests fail and so does the pipeline.
Fortunately none of those variables are things our piglit invocation
needs. Since I've failed to rebuild the docker image as yet, just clear
the likely variables from the environment before running piglit.

Believe it or not, somehow we've never done this in legacy mode! We
currently simply change the DPMS property on the CRTC's output's
respective DRM connector, but this means that we're just setting the
CRTC as inactive-not disabled. From the perspective of the kernel, this
means that any shared resources used by the CRTC are still in use.
This can cause problems for drivers that are not yet fully atomic,
despite using the atomic helpers internally. For instance: if CRTC-1 and
CRTC-2 are still enabled and use shared resources within the kernel (an
MST topology, for example), and then userspace tries to go enable CRTC-3
on the same topology this might suddenly fail if CRTC-3 needs the shared
resources CRTC-1 and CRTC-2 are using. While I don't know of any
situations in the mainline kernel that actually trigger this, future
plans for reworking the atomic check of MST drivers are absolutely
going to make this into a real issue (they already are in my WIP
branches for the kernel).
So: actually do the right thing here and disable CRTCs when they're not
going to be used anymore, even in legacy mode.

The buffer release queue has two kinds of entries:
* Pending async flips.
* Completed flips waiting for their buffer to be released by the Wayland
compositor.
xwl_present_timer_callback neither completes async flips nor releases
buffers, so the timer isn't needed for the buffer release queue.
Fixes issue #12. Presumably the problem was that Present operations on
unmapped windows were executed immediately instead of only when reaching
the target MSC.
When a window is unrealized, a pending frame callback may never be
called, which could result in repeatedly freezing until the frame timer
fires after a second.
Fixes these symptoms when switching from fullscreen to windowed mode in
sauerbraten.
There's no need to keep track of the window which last performed a
Present flip. This fixes crashes due to the assertion in
xwl_present_flips_stop failing. Fixes issue #10.
The damage generated by a flip only needs to be ignored once, then
xwl_window::present_flipped can be cleared. This may fix freezing in
the (hypothetical) scenario where Present flips are performed on a
window, followed by other drawing requests using the window as the
destination, but nothing triggering xwl_present_flips_stop. The damage
from the latter drawing requests would continue being ignored.
If the server resets, most client workqueues are cleaned up as the
clients are killed.
The one exception is the server's client, which is exempt from
the killing spree.
If that client has a queued work procedure active, it won't get
cleared on reset.
This commit ensures it gets cleared too.
c67f2eac56 ("dix: always send focus event on grab change") made dix
always sent events when it's a NotifyGrab or NotifyUngrab, even if
from == to, because 'from' can just come from a previous XSetInputFocus
call.
However, when an application calls XGrabKeyboard several times on
the same window, we are now sending spurious FocusOut+FocusIn with
NotifyGrab, even if the grab does not actually change. This makes screen
readers for blind people spuriously emit activity events which disturb
screen reading workflow when e.g. switching between menus.
This commit avoids calling DoFocusEvents in that precise case, i.e. when
oldWin is a previous grab and the new grab is the same window.
