Screenshots of the outputs can only be taken by having a keyboard
plug-ed in, as to avoid potential malicious intent. On the other hand,
this is problematic as there are cases where a keyboard cannot
be used as a input device. A particular use-case is that for
multiple devices it can be cumbersome to connect a keyboard such
that using ssh can be much easier and can be further automated.
This patch allows taking screenshots without the need of having a
keyboard connected when debug protocol is enabled.
Add also a few words about the fact that this is a serious issue

Meson is a build system, currently implemented in Python, with multiple
output backends, including Ninja and Make. The build file syntax is
clean and easy to read unlike autotools. In practise, configuring and
building with Meson and Ninja has been observed to be much faster than
with autotools. Also cross-building support is excellent.
More information at http://mesonbuild.com
Since moving to Meson requires some changes from users in any case, we
took this opportunity to revamp build options. Most of the build options
still exist, some have changed names or more, and a few have been
dropped. The option to choose the Cairo flavour is not implemented since
for the longest time the Cairo image backend has been the only
recommended one.
This Meson build should be fully functional and it installs everything
an all-enabled autotools build does. Installed pkg-config files have
some minor differences that should be insignificant. Building of some
developer documentation that was never installed with autotools is
missing.
It is expected that the autotools build system will be removed soon
after the next Weston release.

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.

shares the framebuffers between all cloned heads.
All the fields that are obviously properties of the monitor are moved

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.

One reason to catch SEGV and ABRT was to attempt to restore the VT on

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
