This is a common practice in C projects, which simply enforces that
each header must compile cleanly without implicit dependencies on
other headers (see also the previous commit).
We have several wlr_output_* functions which are just wrappers around
corresponding wlr_output_state_* functions and don't actually touch the
wlr_output itself. These probably made some sense historically, but IMHO
they are just confusing now. So remove them and call wlr_output_state_*
directly.
Rename wlr_output_commit() (still useful) to output_state_commit().
