Leandro Ribeiro c9b7c7085a backend-drm: add scanout tranche even for views eligible for direct scanout 
We log the reasons why the fb of a certain view was not placed in an
overlay plane and use that for debug purposes. With these reasons we
also decide if the scanout tranche should be included on the dma-buf
feedback or not. For instance:

  1. If the reason is the incompatibility between the format/modifier
     pair of the fb and those supported by the KMS device, the scanout
     tranche is added and feedback is re-sent (so that the client can
     re-allocate with parameters that makes it eligible for direct
     scanout).

  2. If the reason is because we have no overlay planes available, the
     scanout tranche is useless. So the scanout tranche is removed and
     the feedback re-sent (so that clients can re-allocate with
     parameters optimal for the render device).

Also, when we detect that a view is eligible for direct scanout, we
don't even consider sending new feedback, as our interpretation of the
dma-buf feedback spec was that we should avoid bothering clients with
new feedback when they are already hitting direct scanout.

After some discussions and clarifications regarding the spec, we've
realized that Weston should start to also include the scanout tranche
even when the compositor is able to place client's content on overlay
planes. Basically, because this gives a chance for clients to
re-allocate with the proper parameters (not only format/modifier pair,
but also the target_device and the flags) from the scanout tranche. In
this patch we start doing this.
