Mir's grey background looks ugly on phone

Yes, grey shows you that the shell has failed to paint pixels where it should have, when it should have.

But to make it seamless we need more compositing hooks so the shell can override Mir's default clear function. It's bad for the shell to assume Mir will clear the screen to black all the time.

Actually, the seamless transition work does require Mir changes. But I would like to leave the default grey so we can see where the transition is not yet seamless.

I give in. We don't have an immediate timeline for when compositing control will be available to shells. So the workaround is to go back to the old black.

  * ipc: add a protocol version to the wire protocol so that we can bump
    it in future.
  * graphics::nested: Handling of output configuration changes.
  * graphics.nested: Hookup NestedDisplay to display change
    notifications.

  [ Daniel van Vugt ]
  * Introducing mir_demo_client_progressbar. It's pretty boring;
    designed to simulate key repeat scrolling in a terminal, as an aid
    for tracking down bug 1216472. . (LP: #1216472)

  [ Eleni Maria Stea ]
  * changed the GBMBufferAllocator constructor and class to use the
    gbm_device instead of the GBMPlatform to remove the dependency from
    the mg::Platform interface - this way we can use the
    GBMBufferAllocator with the NativeGBMPlatform (nested mir).
