[PATCH weston v11 00/13] DRM state tracking

[Daniel Stone]

Hi,
This is a re-send of a very limited part of the atomic series. This
pulls us through the state rework, up until the point of merging
DPMS tracking into output state tracking. I managed to find two separate
bugs in that today - and only fix one - so am going to hold off on
pushing that for more review until I've got it fixed.

In the meantime, I've gone through these preparatory patches - which at
least get all the core state tracking in place. Just having these ready
for beta would be a giant step forward, and then I can get some time to
rework DPMS etc.

Cheers,
Daniel
