Guillaume Desmottes da07a647b8 omx: add API to implement dynamic buffers support 
OMX 1.2.0 introduced a third way to manage buffers by allowing
components to only allocate buffers header during their initialization
and change their pBuffer pointer at runtime.
This new feature can save us a copy between GStreamer and OMX for each
input buffer.

This patch adds API to allocate and use such buffers.
