This makes it possible for GCC to print more warnings. For instance,
the docs for -Wmaybe-uninitialized state [1]:
> These warnings are only possible in optimizing compilation, because
> otherwise GCC does not keep track of the state of variables.
Other warning options have similar requirements as well.

ffmpeg, epoll-shim, libpng were dependencies for client examples.
These have been split into a separate repository so we no longer
need to install them.
The dep allows us to check dep variables to discover supported
features. With the binary we assume none of the features are
supported. If a user forgets to install the pkg-config file (e.g.
because it's in a split package) we end up incorrectly disabling
all features. Instead let's error out.
This new renderer is implemented with the existing wlr_renderer API
(which is known to be sub-optimal for some operations). It's not
used by default, but users can opt-in by setting WLR_RENDERER=vulkan.
The renderer depends on VK_EXT_image_drm_format_modifier and
VK_EXT_physical_device_drm.

New warnings can be hard to notice in CI, since CI will just pass in
that case. Meson sometimes uses warnings for important mistakes, e.g.
invalid option.
Let's turn warnings into errors so that we can spot these more easily.
This allows us to validate the objcopy trick in CI. It's basically free
to build both static and shared libraries anyway.
We only enable this for GCC builds right now, as Meson currently lacks
support for prelinking with other compilers.
Use 128-bit hexadecimal string tokens generated with /dev/urandom
instead of UUIDs for xdg-foreign handles, removing the libuuid
dependency. Update readme and CI. Closes#2830.
build: remove xdg-foreign feature
With no external dependencies required, there's no reason not to always
build it. Remove WLR_HAS_XDG_FOREIGN as well.
Check that the pkg-config file is available. This will be required
in the future to check whether xwayland supports features such as
-listenfd, -initfd or -verbose.
If there's no pkg-config file, check that the Xwayland executable
is available.
This effectively makes our relationship with xwayland closer to what
a dynamic library is: checked at build-time, but can be overridden
at run-time.
This is simply a false sense of security, and is worse than just using
setuid. CAP_SYS_ADMIN is an extremely serious capability that is
effectively as powerful as root.
It also required users to be in the input group, which allows any
process to keylog the entire system.
