Instead of closing the window directly by calling close_handler() use a
deferred task to do that instead.
That way we avoid a potential invalid access on a link which was
previously removed, due to the fact both window_destroy() and
touch_handle_up() traverse the same list.
This is an alternative to 841.

Commit 62ab6891db intended to change the angle calculation
so that the a time delta since the first frame would be used
instead of the absolute time. That was done in order to ensure
the angle would always start with the same value, allowing users
to differentiate left and right, which again is needed when
testing flipped transforms.
However, the `benchmark_time` variable is unsuitable for that
purpose as it gets reset on each benchmark interval, abruptly
changing the angle.
Thus introduce a dedicated variable.

Buffer scale is common enough in the modern desktop space to
expect average GL clients to handle it. Thus lets include it into
our main example client.
While on it, also handle buffer transforms. It's essentially free
for GL clients in terms of computing power but may increase the
chance that Wayland compositors are able to hit scanout fast paths.
Thus having an example client for it is likely valueabel for client
and compositor developers.

Setting the opaque region correctly is common source of error for
clients that simply want to express that a whole surface is opaque.
This is especially true once buffer_scale and buffer_transform come
into play, as unlike for damage, where buffer_damage is the
encouraged and user friendly way today, opaque regions are always
in logical coordinates.
As faulty opaque regions don't have a visual impact in these cases
but only increase resource consumption, these errors often remain
for long times. See
1e2bc68171
for one of many examples.
Give an easy example how to set the opaque region in a conformant
and reliable way.

Compositors may choose to send multiple scanout or non-scanout
tranches. So instead of assuming that the first respective tranche
contains the format/modifier we're looking for, check all tranches.
While on it, make sure that in case a compositor sends scanout
tranches on the initial feedback, `pick_format_from_scanout_tranche()`
does not unintentionally pick `INITIAL_BUFFER_FORMAT`.

Weston uses a timeout of 2 seconds before it sends scanout
tranches to clients in order to not trigger excessive buffer
reallocations in clients.
`simple-dmabuf-feedback` in turn counts redraws (200) before

Rather than creating the wl_egl_window at the same time as wl_surface,
do it after we get the first configure event.
With it, we also defer eglMakeCurrent() as according to the spec, the
first time a OpenGL or OpenGL ES context is made current, the viewport
and scissor dimensions are set to the size of the draw surface.
This is particulary important when attempting to start simple-egl either
as fullscreen or as maximized, as not doing so will either incorrectly
commit a buffer with the original dimensions, and later on to resize to
the correct dimensions (which is the case for fullscreen), or it will
terminate the wayland connection abruptly due to xdg-shell protocol
violation, with a mismatch for the client's geometry (the case for
maximized).

This fixes an issue when running simple-dmabuf-feedback:
"wl_display@1: error 1: invalid arguments for wl_surface@3.attach".
As we are not using create_immed request from zwp_linux_dmabuf_v1, we
can't start to use a dma-buf buffer before we process compositor's event
telling us that the creation succeeded.
This was causing problems in the following scenario:
1. buffer is marked to be recreated (because of dma-buf feedback);
2. in buffer_release() event, we destroy the buffer and recreate it;
3. after we recreate it, roundtrip is not called, as we don't want to
block during the drawing loop;
4. buffer status is not being properly tracked, so we are trying to
use a buffer before receiving the event from the compositor telling
us that the creation succeeded.
To fix this, this patch improves buffer status tracking. Now we only
pick a buffer in the drawing loop when it is available. Also, if we have
no buffers available we perform a roundtrip and try again, as we may
have recreated all of them but still didn't have the chance to process
compositor's events telling us that creation succeeded.

Using `pixel_format_get_info()` can result in formats being

Since commit 992ee045f1 we create a new surface when we update the cursor
image. This broke animated cursors by discarding any existing frame
callback used for timing, and moving the setup for frame callbacks to
after the commit on the pointer surface.
To fix this we need another surface commit for the frame callbacks, but
this alone is not enough to fix the regression, as a lingering kludge
intended to fix problems when reusing the pointer surface is no longer
working as intended.
Since we no longer re-use the same surface, we can delete the old surface
on pointer exit, along with any callbacks set on it. Then a frame callback
will be recreated naturally. This lets us remove the now broken kludge
from the past and restore animated cursor functionality.

As mesa includes gbm_bo_get_fd_for_plane() from 21.1.0 version onwards,

Constraining the buffer size of an EGLConfig to 32 means that
the sum of red, green, blue, and alpha channels must equal 32.
This constraint prevented weston-simple-egl from picking an
RGBX pixel format when an opaque surface was asked for, since
the typical RGBX pixel formats have buffer sizes of 30, 24,
and 16.

When trying to get Weston to run on a new system I was building up bit
by bit, I encountered a problem: when I started weston-terminal, it
would close a split second later. This turned out to be because
weston-terminal defaults to trying to spawn /bin/bash, which my
busybox-based system didn't have.
I can configure the terminal to use a shell I do have, of course, but I
think /bin/sh is a much friendlier default, because it's more likely to
exist (POSIX requires it), and will save people just trying to get
started with Weston from the confusing experience I had. I think it's
better overall that somebody who specifically wants /bin/bash has to
configure that (if they even have to — depending on how they're running
Weston, $SHELL might already be /bin/bash) than somebody who just wants
to see the terminal working debug why it won't launch at all.
I realise there might be a (small) backward compatibility concern here
as well, but I hope I've made the case for a friendlier default.

- perform a redraw after we have receiving the initial configure event,
as to draw to working area where to user can use it for receving touch
