Simon Ser ee5f98ad49 output: atomic mode, enabled, scale and transform
This commit makes more output properties (mode, enabled, scale and transform)
atomic. This means that they are double-buffered and only applied on commit.

Compositors now need to call wlr_output_commit after setting any of those
properties.

Internally, backends still apply properties sequentially. The behaviour should
be exactly the same as before. Future commits will update some backends to take
advantage of the atomic interface. Some backends are non-atomic by design, e.g.
the X11 backend or the legacy DRM backend.

Simon Ser ce3f4c3fe1 output: remove wlr_output_impl.transform
The backend doesn't need to handle transform changes, since everything is done
in software. In fact, all of the implementations were all identical and just
set the transform.

We could add support for hardware transforms, but:

- This would require a different field (something like hardware_transform)
- Not all combinations are possible because there often are hardware
  limitations
- The Wayland protocol isn't ready for this (in particular xdg-output, see [1])

This belongs to a different patch series anyway.

Simon Ser 9a0f8a194c output: refactor backend API
This updates the backend part of the output API. This is mostly renaming:
make_current becomes attach_render and swap_buffers becomes commit.

This also fixes the RDP backend to support NULL damage.

Brian Ashworth 6b7f5e4010 backend/noop: improve output number handling
This improves the way the output numbers are handled for the noop
backend. Instead of using the number of active outputs plus one, the
last used number is stored and new outputs will increment it. This
fixes the situation where you start with one output, create a second,
close the first, and create a third. Without this, both outputs will be
NOOP-2, which causes an issue since the identifier will also be
identical. With this, the last output is NOOP-3 and the outputs can be
distinguished.

Ryan Dwyer 9b4be5a595 Introduce noop backend
The noop backend is similar to headless, but it doesn't contain a
renderer. It can be used as a place to stash views for when there's no
physical outputs connected.
