Using `pixel_format_get_info()` can result in formats being
reported as `UNKNOWN` when used on compositors other than Weston.
As `weston-simple-dmabuf-feedback` somewhat succeeds `wayland-info`
as tool for `zwp_linux_dmabuf_v1` debugging from version 4 on, copy
the approach from the later for these cases.

In certain situations these clients crash a lot due to the low
buffer limit. Four buffers is also what EGL allows without blocking
and what is arguably the upper limit of what a compositor should
demand.

It's invalid for a client to pass the compositor's supported version
directly to wl_registry_bind. For instance, under wlroots the client
will bind to wl_output version 4 and crash because it doesn't handle
the new "name" event.

Simple client to test the dma-buf feedback implementation. This does not
replace the need to implement a dma-buf feedback test that can be run in
the CI. But as we still don't know exactly how to do this, this client
can be helpful to run tests manually.
