Check for a potential string trunction. Move the check in a separate

Currently weston-launch does not activate the VT when opening the
terminal directly (e.g. using --tty=/dev/tty7). Weston takes full
control over the terminal by switching it to graphical mode etc.
However, the old VT stays active as can be seen when looking at
sysfs:
# cat /sys/class/tty/tty0/active
tty1
Always switch to the new VT to make sure the correct VT is active.
This aligns with how TTY setup is implemented in launcher-direct.c.

In case an user is given but no tty, the code opens tty0 to allocate a
new tty. With that ttynr is known.
In case a tty name is given the user must be given too. In this case
we later recover the ttynr by using stat on the file tty file descriptor
which allows as to find the ttynr by looking at the devices minor number.
However, the third case, when no user and no tty name is given, we do
not get the ttynr.
This hasn't been a problem in practise since ttynr has not been used.
However, it makes sense to get the ttynr always for consistency. Also
upcomming fixes will start to make use of ttynr.

The tty file descriptor is used in signal handling (when switching
VT via SIGUSR1/SIGUSR2 for the VT_RELDISP ioctrl) and in quit() when
weston-launch exits for the KDSKBMUTE/KDSKBMODE/KDSETMODE/VT_SETMODE
ioctrls.
This fixes VT switching when using weston-launch from a non-VT shell
(e.g. ssh or from within a container).

The only reason why we have both weston_compositor_tear_down() and
weston_compositor_destroy() is that the only we had to destroy
the log context was keeping weston_compositor alive and calling
weston_log_ctx_compositor_destroy().
After commit "weston-log: replace weston_log_ctx_compositor_destroy()
by weston_log_ctx_destroy()", it's not necessary to keep a zombie
weston_compositor just to be able to call
weston_log_ctx_compositor_destroy().

The function weston_log_ctx_compositor_destroy(), which destroys struct
weston_log_context, takes weston_compositor as argument. We may have a
weston_log_context unlinked from a weston_compositor and currently there
is no way to destroy it.
Add function weston_log_ctx_destroy(), what makes the destruction of
weston_log_context independent of weston_compositor.
With this change, one could destroy a weston_compositor and keep the
related weston_log_context (since now weston_log_context can be destroyed
without the need of a weston_compositor). But if weston_compositor gets
destroyed it's also necessary to destroy weston_log_context::global,
as the debug protocol depends on the compositor. So a listener has been
added to the destroy signal of weston_compositor.

Signed-off-by: Stefan Agner <stefan@agner.ch>
The RDP-backend is reporting a non-zero physical size
value, and there are some clients that get the resolution
in pixels directly from the physical size reported. This
leads to a resolution of 25.4 PPI (or 1px/1mm), which is too
small.
But there's no need for that. The physical size is reported
on enabling the output (in the case of RDP-backend we have
no information about it before this), and the resolution is
already set in this moment.
Report a zero physical size to compositor, what makes frontend
and clients use their default values and applications become
readable.

When the aspect-ratio-aware mode support was added to Weston, it was
done before the libdrm support was finalised and merged. Between it
being added to Weston and being merged, it changed to no longer provide
the offset for the bitmask.
Instead of using the mask and a compatible enum, if we update our
libdrm dependency, we can use the flag definitions directly from libdrm.
In 94e4068ba1, the libdrm dependency was bumped to 2.4.83, which
enabled us to remove a bunch of error-prone ifdefs by making atomic and
modifier support mandatory.
We determined in the discussion of !311 that it was safe to push the
dependency as high as 2.4.91, as that was what was available in major
distributions.
Bumping to 2.4.86 allows us to safely remove the ifdef and go with
upstream flags, as that was added in mesa/drm@0d889201d106.

Mode change from mixed-mode to renderer-only means we should no longer

This introduces a new convention of checking through the compositor destroy
listener if the plugin is already initialized. If the plugin is already
initialized, then the plugin entry function succeeds as a no-op. This makes it
safe to load the same plugin multiple times in a running compositor.
Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.
All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
did not fit there.
Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.
Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.
