4629d0ef40 output: expose wlr_output_state_finish()
Same as the original function, but check for the bitfield before
calling pixman_region32_fini(), because that function expects an
initialized region.

a0345f2854 output: add wlr_output_state.allow_artifacts
When starting up, the compositor might call wlr_output_set_mode()
with a mode which is already the current one. wlroots will detect
this and make the wlr_output_set_mode() call a no-op. During the
next wlr_output_commit() call, wlroots will perform an atomic
commit without the ALLOW_MODESET flag.

This is an issue, because some drivers need ALLOW_MODESET even if
the mode is the same. For instance, if the FB stride or modifier
changed, some drivers require a modeset.

Add a new flag "allow_artifacts" which is set when the compositor
calls mode-setting functions. Use this flag to figure out whether
we want to perform atomic commits with ALLOW_MODESET.

(The name "allow_artifacts" is picked because ALLOW_MODESET is a
misnomer, see [1].)

6688a3d9ea output: add output state setters
This ensures compositors don't forget to set the committed flag
or the mode_type when setting a field.
