4e1d9bc72f libweston: Allow taking screenshots when debug protocol is enabled
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
and can lead to silently leaking the output contents.

ad0d83bd6f Don't look for weston.ini in the current working directory
It's a bit surprising that Weston looks different when launched from the root
of the git repo vs from elsewhere.

But it's also technically a security vulnerability: if I launch it from
a directory like /tmp, it might pick up a weston.ini created by another user,
which could then load modules with arbitrary code. Basically, it's the same
problem as including "." in $PATH.

bb707dc0fe weston: remove SEGV and ABRT handlers
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.

1fdeb68013 weston: add wait-for-debugger option
When you need to start Weston via weston-launch, systemd unit, or any
other runner, it is annoying to try to get in with a debugger,
especially if the thing you are interested in happens at start-up. To
make it easy, a new option is introduced.

The new option, implemented both as a command line option and a
weston.ini option, raises SIGSTOP early in the start-up, before the
weston_compositor has been created. This allows one to attach a debugger
at a known point in execution, and resume execution with SIGCONT.

b37ac4006a desktop-shell: remove screensaver support
This is a follow-up for the patch that removed weston-screensaver. The
aim is to clean up shell.c a little by removing non-essential
components. Vanilla Weston desktop is only a demo, external projects are
encouraged to create user-friendly desktop environments.

The support for launching a screensaver client and the protocol bindings
are removed. With them, all related configuration options are removed,
and the manuals are updated accordingly.

The screensaver protocol definition is left in desktop-shell.xml for
posterity.

This does not affect Weston's or desktop-shells ability to put screens
to sleep after inactivity. The inactivity timer continues to operate as
before. Also screen locking is unaffected.

8a0e0ba66a compositor: add option to specify a weston.ini
Add a command line option to specify a file to be read instead of
weston.ini.

IVI-shell testing will at least temporarily need to specify a config
file, because it cannot run without. That is why this is being added,
but should be convenient for everybody, too.

6c71aaeec5 Pass config file from compositor to everything
We have the Weston command line option '--no-config' which is meant to
prevent loading weston.ini at all. It works for Weston itself, but it
does not work for any clients that also want to read weston.ini.

To fix that, introduce a new environment variable WESTON_CONFIG_FILE.
Weston will set it to the absolute path of the config file it loads.
Clients will load the config file pointed to by WESTON_CONFIG_FILE. If
the environment variable is set but empty, no config file will be
loaded. If the variable is unset, things fall back to the default
"weston.ini".

Note, that Weston will only set WESTON_CONFIG_FILE, it never reads it.
The ability to specify a custom config file to load will be another patch.

All programs that loaded "weston.ini" are modified to honour
WESTON_CONFIG_FILE.
