Since drm-backend requires libgbm 21.1.1, client samples using dmabuf

The 'confine' client is used to showcase the behavior of pointer confinement
through the interface zwp_confined_pointer_v1.
Since zwp_confined_pointer_v1 is part of pointer constraints in general, which
includes pointer locking, it makes sense to augment the scope of the client so
it can serve as a showcase for this category of interfaces through
zwp_pointer_constraints_v1.
Currently 'confine' relies on, and is designed around the limitations of, the
toytoolkit. Adapting the toytoolkit for the new requirements proved
unproductive, especially since we wish to add support for pointer constraints in
sub-surfaces. Hence the solution adopted was to write a new client that would
replace the previous one.
This patch introduces the new client, 'constraints.c', replacing 'confine.c'.

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.

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.

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.

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.

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.

As mesa includes gbm_bo_get_fd_for_plane() from 21.1.0 version onwards,
build the dma-buf feedback client only after that. This should provide
some sanity for package maintainers, as this would need pulling a
rather newer mesa version to build it (which might not be available).

wl_shell is officially deprecated so remove support for it and
instead add support for xdg-shell. With it, we've further:
- moved out the buffer handling into its own a distinct structure in
case we might want to do multi-buffer rendering
- 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
events
Additionally we are setting an appid in case one might want to use it in
tandem with kiosk-shell as to be able to place it on a
distinct/different output.

Makes use of weston-direct-display protocol to pass the dmabuf
straight to the display-controller if such a path is possible.
Removes the Y_INVERT flag in case that was passed, and notifies
the user about it, as the weston implementation would force going
through the renderer when passing the Y_INVERT flag, but in the same
time direct-display avoids any GPU import so having them both in the
same time would result into weston refusing the create a buffer.

This client contains driver-specific code to allocate buffers. However clients
shouldn't contain driver-specific code and should rely on e.g. mesa to allocate
buffers via standard interfaces.
Additionally, because the build system always tries to enable all features, some
experimental drivers and drivers that aren't included in amd64 distribution
packages were required. Users would need to manually disable some drivers.
Releasers would need to install libdrm from source (because the release process
forbids adding custom build flags). Dropping simple-dmabuf-drm simplifies both
building and releasing.
The functionality previously tested via simple-dmabuf-drm can now be tested with
simple-dmabuf-egl.

Define common_inc which includes both public_inc and the project root directory.
The project root directory will allow access to config.h and all the shared/
headers.
Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common
#include directive style, as e.g. including shared/ headers without the
subdirectory name no longer works.
Unfortunately this does not prevent one from using private libweston headers
with the usual include pattern for public headers.

Add a client that uses EGL/GLESv2 to draw to dmabuf buffers, utilizing
EGLImages and FBOs. The client uses GBM to create the dmabufs buffers.
The simple-dmabuf-egl client is partly based on patch [1] that changes

simplified since in this case we don't require direct pixel access or

Meson is a build system, currently implemented in Python, with multiple
output backends, including Ninja and Make. The build file syntax is
clean and easy to read unlike autotools. In practise, configuring and
building with Meson and Ninja has been observed to be much faster than
with autotools. Also cross-building support is excellent.
More information at http://mesonbuild.com
Since moving to Meson requires some changes from users in any case, we
took this opportunity to revamp build options. Most of the build options
still exist, some have changed names or more, and a few have been
dropped. The option to choose the Cairo flavour is not implemented since
for the longest time the Cairo image backend has been the only
recommended one.
This Meson build should be fully functional and it installs everything
an all-enabled autotools build does. Installed pkg-config files have
some minor differences that should be insignificant. Building of some
developer documentation that was never installed with autotools is
missing.
It is expected that the autotools build system will be removed soon
after the next Weston release.
