The new calibrator uses weston_touch_calibration protocol extension and
provides the following features:
- chooses the physical touch device to be calibrated by DEVPATH or by
the output/head name; device enumeration provided
- the compositor ensures the calibrator window is shown in the correct
position and size
- no matter how wrong the old calibration is, the touch events will
always arrive in the application
- the calibration is complete, not incremental; the received touch
events are guaranteed to be unmodified
- computes a libinput style calibration matrix directly, not the
WL_CALIBRATION format
- supports multiple touch devices: calibrate one device at a time, and
show user feedback on touching a wrong device instead of recording bad
data
- uses four touch point samples: three to compute the calibration, and
one to verify the calibration is roughly correct
- consistent exit codes
- upload the new calibration into the server after successful
and verified calibration
Due to using special touchscreen calibration protocol extension, this
application cannot be tested without touch input from the compositor.
Practically all of the above mentioned are unlike how the old
calibrator client worked.
Co-developed by Louis-Francis and Pekka.

This implements a new global interface weston_touch_calibration, which
allows one client at a time to perform touchscreen calibration. This
also implements the calibrator window management.
A client asks to calibrate a specific physical touch device (not a
wl_seat which may have several physical touch devices aggregated).
Libweston grabs all touch devices and prevents normal touch event
handling during the calibation sequence.
API is added to enable this new global interface, but it not yet called
by anything. Since the implementation allows clients to grab touch devices
arbitrarily, it is not enabled by default. The compositor should take
measures to prevent unexpected access to the interface.
A client may upload a new calibration to the compositor. There is a
vfunc to allow the compositor to reject/accept it and save it to
persistent storage. The persistent storage could be a udev rule
setting LIBINPUT_CALIBRATION_MATRIX, so that all display server would
load the new calibration automatically.
Co-developed by Louis-Francis and Pekka.

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.

The Mesa change has since been reverted (Mesa commit 9ca6711faa), as
this had unpleasant interactions with buffer_age in particular, so this
test is no longer valid.
Additionally, it only worked on backends which initialised EGL (not
headless-backend, where tests generally run), which can be flaky due to
initialisation races. Not only that, but on the DRM backend, we can
legitimately enter triple-buffering due to promoting the surface to a
