This adds support for RandR CRTC/Output leases through the modesetting
driver, creating a lease using new kernel infrastructure and returning
that to a client through an fd which will have access to only those
resources.
v2: Restore CRTC mode when leases terminate
When a lease terminates for a crtc we have saved data for, go
ahead and restore the saved mode.
v3: Report RR_Rotate_0 rotations for leased crtcs.
Ignore leased CRTCs when selecting screen size.
Stop leasing encoders, the kernel doesn't do that anymore.
Turn off crtc->enabled while leased so that modesetting
ignores them.
Check lease status before calling any driver mode functions
When starting a lease, mark leased CRTCs as disabled and hide
their cursors. Also, check to see if there are other
non-leased CRTCs which are driving leased Outputs and mark
them as disabled as well. Sometimes an application will lease
an idle crtc instead of the one already associated with the
leased output.
When terminating a lease, reset any CRTCs which are driving
outputs that are no longer leased so that they start working
again.
This required splitting the DIX level lease termination code
into two pieces, one to remove the lease from the system
(RRLeaseTerminated) and a new function that frees the lease
data structure (RRLeaseFree).
v4: Report RR_Rotate_0 rotation for leased crtcs.
v5: Terminate all leases on server reset.
Leases hang around after the associated client exits so that
the client doesn't need to occupy an X server client slot and
consume a file descriptor once it has gotten the output
resources necessary.
Any leases still hanging around when the X server resets or
shuts down need to be cleaned up by calling the kernel to
terminate the lease and freeing any DIX structures.
Note that we cannot simply use the existing
drmmode_terminate_lease function on each lease as that wants
to also reset the video mode, and during server shut down that
modesetting: Validate leases on VT enter
The kernel doesn't allow any master ioctls to run when another
VT is active, including simple things like listing the active
leases. To deal with that, we check the list of leases
whenever the X server VT is activated.
xfree86: hide disabled cursors when resetting after lease termination

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.

Now that we can actually configure all of the directories xkb uses for
finding things, we can (finally, but only with meson) finally make it so
that with the correct meson configuration the Xserver will "just work"
without any additional changes to the installation prefix after
building.
For the people like me who have since scripted this part out of their
build process and forgotten about it, building and installing the X
server into a non-standard prefix has always required the following (or
something else that makes sure that X has a valid xkbcomp configuration)
commands be run right after doing the installation:
# start in root of prefix you installed X to
mkdir -pv share/X11/xkb/rules
ln -s /usr/share/X11/xkb/rules/evdev share/X11/xkb/rules/
rm -f bin/xkbcomp
ln -s /usr/bin/xkbcomp bin/
The one last piece of getting rid of this post-install junk is making
sure that we can control the directory that X uses for finding the
xkbcomp binary from meson so we can point it at the system provided
xkbcomp (/usr/bin/xkbcomp or similar). So, this patch adds a
configuration option for controlling this called xkb_bin_dir.

Special case for the systemd-logind case in xfree86: when we're vt-switched
away and a device is plugged in, we get a paused fd from logind. Since we
can't probe the device or do anything with it, we store that device in the
xfree86 and handle it later when we vt-switch back. The device is not added to
inputInfo.devices until that time.
When the device is removed while still vt-switched away, the the config system
never notifies the DDX. It only runs through inputInfo.devices and our device
was never added to that.
When a device is plugged in, removed, and plugged in again while vt-switched
away, we have two entries in the xfree86-specific list that refer to the same
device node, both pending for addition later. On VT switch back, the first one
(the already removed one) will be added successfully, the second one (the
still plugged-in one) fails. Since the fd is correct, the device works until
it is removed again. The removed devices' config_info (i.e. the syspath)
doesn't match the actual device we addded tough (the input number increases
with each plug), it doesn't get removed, the fd remains open and we lose track
of the fd count. Plugging the device in again leads to a dead device.
Fix this by adding a call to notify the DDX to purge any remainders of devices
with the given config_info, that's the only identifiable bit we have at this
point.

Make validGlxDrawable() public
Adjust glxWinSetPixelFormat() so it doesn't require a context, just a
screen and config.
That enables factoring out the deferred drawable creation code as
glxWinDeferredCreateDrawable()
Enhance glxWinDeferredCreateDrawable(), so that pixmaps are placed into a
file mapping, so they exist in memory which can be shared with the direct
rendering process.
Currently, this file mapping is accessed by a name generated from the XID.
This will not be unique across multiple server instances. It would perhaps
be better, although more complicated, to use an anonymous file mapping, and
then duplicate the handle for the direct rendering process.
Use glxWinDeferredCreateDrawable() to ensure the native handle exists for
the Windows-DRI query to map a drawable to native handle.

There's no reason not to offer ridiculous numbers of clients; only a

This converts the dispatch loop into using a list of ready clients
instead of an array. This changes the WaitForSomething API so that it
notifies DIX when a client becomes ready to read, instead of returning
the set of ready clients.

This provides a wrapper around poll or epoll providing a

The timeout resolution offered in the AdjustWaitForDelay call is
only milliseconds, so passing around the timeout as a pointer to a
struct timeval is not helpful. Doing everything in milliseconds up to
the point of the select call simplifies the code without affecting
