This is a big patch with a lot of changes, and I'm worried about landing
it right as we're on the eve of beta. If it could be broken up into
smaller easy-to-review bits, it might make it more digestible...
That said, I like where this is going. I'd be totally okay with landing
it post-release.

"parse" is a bit misleading here, since we're just copying data and not
actually parsing anything anymore. Maybe a more descriptive name would
be something like init_drm_modeinfo() or copy_weston_modeline_to_drm().
This patch also adds a different parse_modeline() over in main.c, which
does actually parse stuff, so a different name here could prevent some
future confusion.
Also, this function would be easy to write a test case for, as it just
copies data from one structure to another.

Nice refactoring. With this change, this function also becomes quite
simple to write a test case for... just pass in various strings and
verify the correct int is returned.

This function has a number of exit points, making it a really good
candidate for writing a thorough collection of test cases. The tricky
bits would be the two drm_output_add_mode() calls, which will need
mocks; initially though a first cut test could leave those two branches
as TODO.
