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 lessee may well have played with cursors and left one
active on our screen. Just tell the kernel to turn it off.
v6: Add meson build infrastructure

Immutable in randr means that clients are not able to alter the

This logically means that the property then should not be deleted

RRPostPendingProperties tries to compare the pending and current
property values to decide whether they're actually changing. However,
it does this using a memcmp that passes in pending_value->size as the
number of bytes. This is actually the number of elements, where each
element is (pending_value->format / 8) bytes long. This causes the
pending value to not be propagated if the first pending_value->size
bytes are the same and only the end of it is changing.
Fix this by computing the total number of bytes to compare in the
memcmp.

This matches the test in TryClientEvents, and is a superset of tests
done by the callers of these functions. The consequence of forgetting
these tests is a server crash, so they're always desirable. In my
opinion, it's better to not require the callers to remember to do these
checks.
For callers that don't do very much work before calling WriteToClient or
WriteEventsToClient, I've removed the redundant checks.
hw/xquartz/xpr/appledri.c has an interesting case: While its check for
"client == NULL" appears redundant with the test in WriteEventsToClient,
it dereferences client to get the sequence number.

Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.
Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.
Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:

In order to report accurate values to users of the RandR property interface,
it's sometimes necessary to ask the driver to update the value (for example
when backlight brightness changes without the server's knowledge, due to hotkey
events or direct sysfs banging).
This patch wires up the core server code with a new xf86CrtcFuncs callback,
get_property, to allow for this.
The new code is available under the RANDR_13_INTERFACE define, which in turn
depends on the RANDR_12_INTERFACE code.
Yes, two changes in one commit. Sorry 'bout that.
The first change ensures that when pending property values have been
changed, a mode set to the current mode will actually do something, rather
than being identified as a no-op. In addition, the driver no longer needs to
manage the migration of pending to current values, that is handled both
within the xf86 mode setting code (to deal with non-RandR changes) as well
as within the RandR extension itself.
The second change eliminates the two-call Create/AttachScreen stuff that was
done in a failed attempt to create RandR resources before the screen
structures were allocated. Merging these back into the Create function is
cleaner.
(cherry picked from commit 57e87e0d00)
Conflicts:
randr/randrstr.h
randr/rrcrtc.c
I think master and server-1.3-branch are more in sync now.
Pending Properties take effect when the driver says they do, so provide an
API to tell DIX when a property effect is made. Also, allow driver
to reject property values in RRChangeOutputProperty.
(cherry picked from commit 8eb288fbd6)
Neglected to change the allocation size from sizeof (PropertyRec) to
sizeof (RRPropertyRec). Lots of fun crashes this way.
(cherry picked from commit 0626eb8e5c)
This patch tracks the protocol changes which introduce more complex
semantics for RandR output properties including pending and valid value
information.
(cherry picked from commit af55c65bea)
Add function to keep pointer within valid crtc areas.
Finish event delivery and swapping code.
Separate configuration from layout changes to send correct events.
Provide a Xinerama implementation when DIX version isn't enabled. This
version exposes each crtc as a separate 'screen' and reports the size of
that patch. The extension also sends ConfigureNotify events to the root
window whenever crtcs change so that applications will re-fetch xinerama
information. This actually works for metacity.
