If the client requests to take a screenshot using the writeback source
with a DMA buffer, Weston will get the framebuffer from that dmabuf
object and attach it to the writeback connector.

The new formats_done event has to be at the end, triggering warnings
like the following otherwise:
warning: since version not increasing
Fixes: 00902a592 (output-capture: Allow multiple formats and add formats_done event)

The writeback output capture source may allow clients to select from
multiple possible formats. Update the protocol and its users
accordingly, and add formats_done event, making the implementation
easier and following common protocol practice.

This is a completely new screenshooting protocol designed to support:
- color management testing by adding the "blending" source
- KMS testing by adding the "writeback" source
- output decorations testing by adding the "full_framebuffer" source
- proper buffer size negotiation instead of guessing from wl_output
- compositor chosen pixel format, primarily for "blending" source
- proper indication of screenshot failure
- dmabuf target buffers, linear only
This new protocol should be good enough to publish as a Weston public
extension. Hence install it.
