When a head is unplugged, the corresponding wl_output is removed. If
that was the wl_output associated with the background and panel
surfaces, we must transfer the ownership to a remaining wl_output that
was a clone to avoid losing the background and panel completely.
The transfer relies on desktop-shell.so implementation to register

Setting state_invalid to true is moved together with the code adding new
unused CRTCs and connectors in drm_output_deinit(). Logically these two
operations belong together: state_invalid is required for the new unused
item to be turned off.
This does not hinder initial turning off of outputs, because on
compositor start-up, state_invalid is initialized to true, making calls
to drm_output_disable() for non-enabled outputs a no-op.
Previous changes already ensure that if a compositor does not explicitly
enable an output, the CRTC and connector will be turned off even without
an explicit disable (provided there is a at least one enabled output).

Rather than smashing the state to disable a CRTC immediately, just
delegate that to the normal repaint cycle by setting state_invalid =
true. drm_pending_state_apply() will pick up the unused_crtcs.
A caveat here is that we have no enabled outputs at all, we will never
enter repaint, and so CRTCs do not actually get turned off until we get
at least one output to drive.
However, this should help the problem reported here:
https://lists.freedesktop.org/archives/wayland-devel/2018-January/036713.html
Arguably it is better to leave an output spuriously on in rare cases
rather than fail modeset completely in somewhat more common cases.
My personal motivation for this change is that it helps if we later move
CRTC allocation to output enable/deinit instead of create/destroy,
because then the CRTC will not be available here for initial turn-off as
the output has not been enabled to begin with.

Catching an ABRT is kind of ok, catching a SEGV is russian roulette. We
have been quite lucky with it, but I've started hitting crashes inside
malloc() which causes a deadlock when our SEGV handler needs to malloc()
as well (weston_log_timestamp()).
One reason to catch SEGV and ABRT was to attempt to restore the VT on
the DRM-backend. Nowadays that job is done by logind or weston-launch.
The signal handler also printed a backtrace, which for me personally has
been extremely helpful. Arguably it's not necessary though, when we have
core files and services that catch cores. For instance, if using
systemd, 'coredumpctl gdb' is delightfully easy for getting into the
saved core.
Therefore, this code does more harm than it is useful, so remove it. We
also drop an optional dependency to libunwind.

Split repaint into two stages, as implied by the grouped-repaint
interface: drm_output_repaint generates the repaint state only, and
drm_repaint_flush applies it.
This also moves DPMS into output state. Previously, the usual way to
DPMS off was that repaint would be called and apply its state, followed
by set_dpms being called afterwards to push the DPMS state separately.
As this happens before the repaint_flush hook, with no change to DPMS we
would set DPMS off, then immediately re-enable the output by posting the
repaint. Not ideal.
Moving DPMS application at the same time complicates this patch, but I
couldn't find a way to split it; if we keep set_dpms before begin_flush
then we break DPMS off, or if we try to move DPMS to output state before
using the repaint flush, we get stuck as the repaint hook generates an
asynchronous state update, followed immediately by set_dpms generating a
synchronous state update.
In drm_output_update_complete, the *_pending flags are cleared
before any of the pending actions are taken; this ensures that the
actions cannot recurse.

If we have an unused CRTC or connector, explicitly disable it during the
end of the repaint cycle, or when we get VT-switched back in.
This commit moves state_invalid from an output property to a backend
property, as the unused CRTCs or connectors are likely not tracked by
drm_outputs. This matches the mechanics of later commits, where we move
to a global repaint-flush hook, applying the state for all outputs in
one go.
The output state_invalid flag originally provoked full changes on output
creation (via setting the flag at output enable time) and session enter.
For the new-output case, we will not have any FB in output->state_cur,
so we still take the same path in repaint as if state_invalid were set.
At session enter, we preserve the existing behaviour: as
start_repaint_loop will fail when state_invalid is set, all outputs will
be scheduled for repaint together, and state_invalid will not be cleared
until after all outputs have been repainted, inside repaint_flush.
