This avoids using the deprecated drm_get_pci_dev() and load() hook
interfaces in the qxl driver.
The only tricky part is to ensure TTM debugfs initialization happens
after the debugfs root node is created, which is done by moving that
code into the debufs_init() hook.
Tested on qemu with igt and running a WM on top of X.
Changes since v1:
- Drop verification for primary minor in qxl_debugsfs_init.
Changes since V2:
- Put new header together with other debugfs headers.

Registering the connector explicitly right after creation is not
necessary for modesetting drivers, because drm_dev_register already takes
care of this on the core side, by calling drm_modeset_register_all.
In addition, performing the initialization too early will get in the way
of the load() hook removal, because the connector interface cannot be
published prior to registering the minors.

<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has
now been split into separate files for each object type, but still
includes most other KMS headers to avoid breaking driver compilation.
As a step towards fixing that problem, remove the inclusion of
<drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where
appropriate. Also remove the forward declarations of the drm_encoder and
drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not
needed in the header.
<drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a
forward declaration of struct drm_encoder in order to allow including it
as the first header in a compilation unit.

The use of drm_cvt_mode() in qxl_add_monitors_config_modes() means that
the resolutions we are going to present to user-space are going to be
rounded down to a multiple of 8. In the QXL arbitrary resolution case,
this is not useful.
This commit forces the actual width/height that was requested by the
client in the drm_display_mode structure rather than keeping the
rounded version.

When the QXL driver receives a QXL_INTERRUPT_CLIENT_MONITORS_CONFIG interrupt,
we currently always notify userspace that there was some hotplug event.
However, gnome-shell/mutter is reacting to this event by attempting a
resolution change, which it does by issueing drmModeRmFB, drmModeAddFB,
and then drmModeSetCrtc. This has the side-effect of causing
qxl_crtc_mode_set() to tell the QXL virtual hardware that a primary
surface was destroyed and created. After going through QEMU and then the
remote SPICE client, a new identical monitors config message will be
sent, resulting in a QXL_INTERRUPT_CLIENT_MONITORS_CONFIG interrupt to
be emitted, and the same scenario occurring again.
As destroying/creating the primary surface causes a visible screen
flicker, this makes the guest hard to use (
https://bugzilla.redhat.com/show_bug.cgi?id=1266484 ).
This commit checks if the screen configuration we received is the same
one as the current one, and does not notify userspace about it if that's
the case.

The qxl driver currently destroys and recreates the
qxl "primary" any time the first crtc is set.
A side-effect of destroying the primary is mouse state
associated with the crtc is lost, which leads to
disappearing mouse cursors on wayland sessions.
This commit changes the driver to reapply the cursor
any time SetCrtc is called. It achieves this by keeping
a reference to the cursor bo on the qxl_crtc struct.

I recovered dri-devel backlog from my vacation, more misc stuff:
- of_put_node fixes from Peter Chen (not all yet)
- more patches from Gustavo to use kms-native drm_crtc_vblank_* funcs
- docs sphinxification from Lukas Wunner
- bunch of fixes all over from Dan Carpenter
- more follow up work from Chris register/unregister rework in various
places
- vgem dma-buf export (for writing testcases)
- small things all over from tons of different people

GCC doesn't complain about this but my static checker does. We're
passing "drawable" before initializing it. It's not actually used so
it's harmless and I just removed it.

System workqueues have been able to handle high level of concurrency
for a long time now and there's no reason to use dedicated workqueues
just to gain concurrency. Since the workqueue in the QXL graphics device
driver is involved in freeing and processing the release ring
(workitem &qdev->gc_workqxl, maps to gc_work which calls
qxl_garbage_collect) and is not being used on a memory reclaim path,
dedicated gc_queue has been replaced with the use of system_wq.
Unlike a dedicated per-cpu workqueue created with create_workqueue(),
system_wq allows multiple work items to overlap executions even on
the same CPU; however, a per-cpu workqueue doesn't have any CPU
locality or global ordering guarantees unless the target CPU is
explicitly specified and thus the increase of local concurrency
shouldn't make any difference.
flush_work() has been called in qxl_device_fini() to ensure that there
are no pending tasks while disconnecting the driver.

When we want to pipeline accelerated moves we need to wait in the fallback path.
