Implement wlr-screencopy v1 (#243)

* Implement wlr-screencopy

* Finish the implementation

Lots of changes, mainly to fix transform handling. Turns out, grim
expects transformed buffers and untransforms them by itself using info
from wl_output. This means that render helpers needed to learn how to
actually render transformed buffers.

Also, it meant that y_invert is no longer needed.

Next, moved the rendering to the Screencopy frame handler. Turns out,
copy() is more or less expected to return immediately, whereas
copy_with_damage() is expected to wait until the next VBlank. At least
that's the intent I parse reading the protocol.

Finally, brought the version from 3 down to 1, because
copy_with_damage() will need bigger changes. Grim still works, others
not really, mainly because they bind v3 unnecessarily, even if they
don't use the damage request.
