When multiple backends are loaded simultaneously, they all have
to register their own head change notification listener and
output configuration callback.
To avoid calling output configuration for heads created by other
backends, only iterate over heads that were created from the given
backend by comparing the weston_head::backend pointer to the one
stored in the head change notification listener.

Before loading a backend, clear the weston_compositor::backend pointer
to check whether the backend supports multi-backend operation and adds
itself to the weston_compositor::backend_list.
Keep weston_compositor::backend pointing to the last loaded backend
either way, to allow the calling compositor code to store it away for
later, to check whether a head belongs to a given backend in the output
configuration code. This workaround can be removed after all backends
are converted to be multi-backend aware.

Add yet another flavor of assertion macros.
Unlike libc assert.h assert(), these cannot be easily disabled by the
build. They also print both the implied expression and the compared
values.
Unlike ZUC macros, there is much less framework code and it can handle
also floating-point types.
The function custom_assert_fail_ can be redefined, meaning that
different compilation units can do different things on failure.
Also the 'compositor' parameter was added to the new macros because we
plan to use these asserts in our log infrastructure, and we want to
print the "failure" messages in the right log scopes. Having the
compositor already in the macros will avoid double work.
Another future possibility is to write specific asserts for the test
suite. So we would be able to write a test suite failure function that
just print what "failed" without aborting.
There is also limited support for custom types.
These are actually pretty similar to libinput's litest macros.

And move it back to its place, as we can't differentiante between two
different states: coming back from unmaxized (which makes it so we send
out a widthXheight size matching that of maximized whereas we should send
out 0, 0) and that we're no longer fullscreen. We land basically in the
same spot in both cases, and trying one issue, creates a new one.
Moving the corner case in set_fullscreen makes it so we don't reach both
cases in the same time and avoid introducing other issues.

harmful to call weston_shell_utils_curtain_destroy() in mid animation. It

Per-output fade animations were a precursor to implementing support for
zwp_idle_inhibit_v1. Nobody ever followed up on that. Now that we have
the ability to create overlapping outputs, per output curtains don't
make sense - the curtains can overlap and look weird.

direction isn't properly covered by the fade.

Allow passing NULL to monitor string in order to set the default
"unknown" strings. This allows a head to be initialized with the default
strings, meaning that it will no longer be mandatory for a backend to

If serial is unknown, it's best to leave it as NULL. All usage sites

serial as NULL, allowing to move the initialization of these fields into
