Add a new output section key "same-as" for configuring clone mode. An
output marked "same-as" another output will be configured identically to
the other output.
The current implementation supports only CRTC sharing for clone mode.
Independent CRTC clone mode cannot be supported until output layout
logic is moved from libweston into the frontend and libweston's damage
tracking issues stemming from overlapping outputs are solved.
Quite a lot of infrastructure is needed to properly configure clone
mode. The implemented logic allows easy addition of independent CRTC
clone mode once libweston supports it. The idea is that wet_layoutput is
the item to be laid out and all weston_outputs a wet_layoutput
contains show exactly the same area of the desktop.
The configuration logic attempts to automatically fall back to creating
more weston_outputs when all heads do not work under the same
weston_output. For now, the fallback path ends with an error message.
Enabling a weston_output is bit complicated, because one needs to first
collect all relevant heads, try to attach them all to the weston_output,
and then back up head by head until enabling the weston_output succeeds.
A new weston_output is created for the left-over heads and the process
is repeated.
CRTC-sharing clone mode is the most efficient clone mode, offering
synchronized scanout timings, but it is not always supported by
hardware.

Migrate the DRM frontend to use the simple head-based output
configurator, maintaining the exact same features and semantics as
before.
This is an intermediate step. It is unoptimal to create a weston_output
just to turn it off, but the libweston implementation and the DRM
backend require it for now. In the future, the DRM frontend will get its
own configurator that does not create useless weston_outputs and
supports clone mode by attaching multiple heads to the same
weston_output. Clone mode is not yet supported by libweston/DRM.
Until we remove the need to create a weston_output just to turn it
"off", that is, disable it, we will hit simple_head_enable() for heads
we have already disabled. As long as the DRM-backend conversion to the
head-based API is not complete, attempting to create an output for a
head again would lead to a crash. This problem does not exist right now,
but it will after the patch "compositor-drm: start migration to
head-based output API". Therefore, check if the head we are about to
process is already attached, and do nothing if so. DRM outputs set to
"off" are the only ones legitimately hitting this condition.
This is the last frontend migrated, wet_set_pending_output_handler() is
deleted as dead code.

In order to support clone modes, libweston needs the concept of a head
that is separate from weston_output. While weston_output manages buffers
and the repaint state machine, weston_head will represent a single
monitor. In the future it will be possible to have a single
weston_output drive one or more weston_heads for a clone mode that
shares the framebuffers between all cloned heads.
All the fields that are obviously properties of the monitor are moved
from weston_output into weston_head.
As moving the fields requires one to touch all the backends for all the
assingments, introduce setter functions for them while we are here. The
setters are identical to the old assignments, for now.
As a temporary measure, weston_output embeds a single head. Also the
ugly casts in weston_head_set_monitor_strings() will be removed by a

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

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

Weston will not repaint until previous update has been acked by a
pageflip event coming from the drm driver. However, some buggy drivers
won’t return those events or will stop sending them at some point and
Weston output repaints will completely freeze. To ease developers’ task
in testing their drivers, this patch makes compositor-drm use a timer
to detect cases where those pageflip events stop coming.
This timeout implementation is software only and includes basic
features usually found in a watchdog. We simply exit Weston gracefully
with a log message and an exit code when the timout is reached.
The timeout value can be set via weston.ini by adding a
pageflip-timeout=<MILLISECONDS> entry under [core]
section. Setting it to 0 disables the timeout feature.
