There are V4L2 devices that will output NV12 but will do so using one dma
buffer. To support this, we need to add the same dma buffer twice but with
a different offset for the chrominance plane.
Also supports situations of 3 planes (e.g. YU12) inside a single dma buffer.

Note that this application does not follow best practices for handling tablet
events. The events are grouped by frame, all processing should be done in the
frame instead of the respective handler.
A good toolkit would accumulate the data in the events and provide them as one
event to the actual client once the frame is received. toytoolkit just hooks
up the handler one-by-one, so we're doing this here as well.

When it comes to a window frame, a tablet tool and cursor act almost
identical; they click things, drag things, etc. The tool type and extra
axes don't serve any use in the context of a window frame, so tablet
pointers share the frame_pointer structures used for the mouse pointer.

Fractional scale is increasingly common in the Wayland ecosystem. Thus,
given simple-egl's role as egl example client, implement support for
the new protocol - even though Weston itself does not support it yet.
Together with buffer_scale and buffer_transform this ensures
simple-egl provides optimally sized and oriented buffers.

There's a comment explaining how to hack the DRM-backend in order to
fake that a certain format is not supported by the KMS device. This is
useful in order to test dma-buf feedback implementations using the
simple-dmabuf-feedback client. But with recent changes on the
DRM-backend, this got outdated.
Drop this comment, as everyone interested in this client is probably
familiar enough with the DRM-backend in order to do that.

Signed-off-by: Michael Tretter <m.tretter@pengutronix.de>
The functionality of this screenshooting helper client is kept exactly
the same as before: if you have multiple outputs, some transformed, some
scale, in any layout, this will create a "multi-image" where the
framebuffer (the physical image) of each output is pasted into a row of
images in the order the outputs were advertised thrugh wl_registry.
Output transform or scale are not accounted for. If you have a monitor
rotated sideways, the screenshot will have the image of that monitor
reverse-sideways.
Otherwise the client is almost completely re-written, so trying to read
the diff is not that useful.
The old screenshooting protocol is replaced with the new
weston-output-capture protocol. This makes it unnecessary to listen for
wl_output information (since we do not handle output transform or scale
anyway).
The buffer sizes and formats are dictated by the compositor, which also
means we cannot hardcode the format. Hence, use Pixman for the blitting,
in case it needs to do format conversion. It is good to get rid of
hand-crafted pixel data manipulation code too.
For that reason we also need a pixel format database to convert between
DRM fourcc, wl_shm and Pixman codes. We link to libweston to borrow its
database instead of inventing another partial copy of it. It's weird to
use compositor library private API in a client, but better than the
alternative.
The original code had no tear-down code at all. Now, if everything
succeeds, the program ends with no unfreed memory according to ASan. If
something fails, it still YOLO's it (doesn't free stuff). That's how far
my pedantry carried.
I also did not bother taking output transform or scale into account,
since the old code did not either. It would be nice to create a seamless
image of the desktop with shots rotated and scaled to align, in the max
scale over all outputs. Meh.

Similar to changes in simple-dmabuf-egl, this perform a x-axis

The motivations for this are:
- Y_INVERT is not used by most real-world clients.
weston-simple-dmabuf-egl and weston-simple-dmabuf-v4l are one only
known users. Thus this creates a special case just for these demo
clients.
- Some compositors (wlroots) have dropped support for DMA-BUF flags,
so the client no longer runs there.
- Dropping the flag allows compositors to use a KMS hardware plane to
display the buffer.
It keeps the same axis orientation we had in place where we had the
y-invert flag enabled by default, by doing a reflection about x-axis.

We have no guarantee that we can create a surface for the pointer at the
instant we receive a seat that will (probably eventually) need one.

If weston-simple-egl is run with the "-b" flag, it will attempt to set
the swap interval to 0 during create_surface. However, at that point, it
will not have made its EGLContext current yet, causing the
eglSwapInterval call to have no effect. To fix this, wait until the
EGLContext has been made current in init_gl before updating the swap
interval.

Recently I learnt that fprintf() is not async-signal-safe. Maybe it also
attempts to allocate memory sometimes. Hence, using it when we
presumably are out of memory is wishful thinking.
Therefore replace that with async-signal-safe code. If you have to check
pointers from traditional signal handlers, now you could do that too!
While doing this, we also lose the string formatting for line number. I
would argue that printing file and line number is not that useful, if
the system really is out of memory. If not out of memory, a core dump
would give us much more detailed information about what went wrong.
clients/window.c had some calls to fail_on_null() and these are simply
replaced. They were used for checking that creating new wl_proxy by
issuing a protocol request worked, and IIRC that only fails on
out-of-memory, so the same rationale applies here.

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.
