Try to force a framebuffer release for an output. 

This tries to release the next or optionally pending, or current buffer from the output. If successful there will be a release callback to the registered handler, and the fb will no longer be flagged busy.

Releasing buffers committed to scanout will potentially cause flicker, so this is only done when the panic flag is set.

Register a callback for buffer status updates. 

When a flip completes ecore\+\_\+drm2 may release a buffer. Use this callback if you need to do bookkeeping or locking on buffer release.

Additionally, an fb may be placed on scanout or removed from scanout by evas. When this happens a compositor needs to ensure the buffers aren\textquotesingle{}t released back to a client while they\textquotesingle{}re on scanout.


\begin{DoxyParams}{Parameters}
{\em fb} & The fb to register the callback on \\
\hline
{\em handler} & The function to handle the callback \\
\hline
{\em data} & The user data to pass to the callback\\
