Hi everyone

A fairly small update to this set, to adopt a couple of things from
Naush and to fix a minor conflict. Mostly things are unchanged, so the
highlights are:

* ColorSpace class as before.

* Two ColorSpace fields in the StreamConfiguration, so that
  validate() can't cause a configuration to become unusable.

* I'm not currently signalling errors if the V4L2 classes get passed
  undefined ColorSpaces. Perhaps something to add once all pipeline
  handlers are upgraded?

* And I'm happy to add commits to fill in a basic level of colour
  space handling in other pipeline handlers (please let me know).

Thanks!

David
