Now that we have a way to prevent repaints of empty scene graphs from
the shells, remove the curtains and just have our first paint be
proper content.

We've added a curtain to the shells so at startup we have something to
render, but this causes a flicker if someone is trying to have a seamless
transition from boot to weston.
Add a ready flag that allows the shell to indicate repaints are safe, so
we can remove the curtains and have no wasted frames at startup.

In a multi-screen setup, removing the first screen triggers `handle_output_move`.
If `weston_view_set_position` is called on an output that has an active popup,
it causes a weston crash due to the view has a parent.

The shell_set_view_fullscreen function was dereferencing
shsurf->fullscreen_output without checking if it was NULL first. This
could lead to a crash when a fullscreen surface had no associated
output during display hotplug.

This already calls either weston_view_add_transform() or
weston_view_remove_transform() followed by
weston_view_update_transform(), the combination of which will already
force a repaint for those views.

With this, when unplugging an extended display, the view displayed on
the extended display won't be re-positioned to other displays.
On some embedded devices, the views are often fullscreen displayed, even
on the extended displays. When disconnecting the extended displays, the
views are not desired to be moved onto the existing displays. Without
this change, we can see the view flash across the existing displays
even though the UI program hides the view as soon as it can, which is
unexpected.

Desktop-shell currently waits for the desktop-shell client to set up a
background image. But the outputs are enabled before this happens, which
forces a repaint.
If the fade animation is enabled, there's a fade curtain in place, but if
it's disabled the scene graph is empty at the repaint.
This repaint with an empty scene graph can have very nasty consequences,
especially if frame buffer compression is in use, as the buffer isn't
rendered into and can be in an undefined state that confuses whatever
video hardware is trying to decode the buffer.
Add a temporary black curtain placeholder that ensures the scene graph has
something in it before the client gets a chance to commit the real
background.

As weston_windowed_output_get_api needs ARRAY_LENGTH() move helpers to a
libweston/ so other users can re-use that instead of re-defining these
all over. Easier for other front-ends to make use of them.
With this change windowed-output-api.h also includes the helpers header.

If the output is destroyed between setting the panel and committing the
panel, or between setting the background and committing the background,
we have a use after free crash.
Handle this by clearing the surface private pointers on output destroy
so we can skip the useless commits.

This change fixes a side-effect of weston_view_move_to_layer helper

Shell fades out and in depending on user interactions. When screen
is faded out, first interaction wakes up the shell from idle and screen
fades back in. However, this first interaction is applied to whatever
is "behind" faded screen and it may trigger unwanted actions (first
touch or mouse click on active GUI elements). Behavior is the same for
both idle and lock screen (because unlock dialog is created after the
first interaction).
Update fade animation curtain creation function to capture inputs in
order to prevent unwanted interactions within faded or locked shell.

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.

There are many times when we want to set a global position with a surface
offset added.
It's a fairly nasty operation, and most places in the code currently do

and other complex transforms that could be in play (but probably aren't)

This is a trap - it's not harmful to let the animation complete - it is
harmful to call weston_shell_utils_curtain_destroy() in mid animation. It
results in immediately completing the animation, which attempts to destroy
the curtain a second time.

during the fade out, then reconnected before the fade-in starts.
