Gwenole Beauchesne 2940a74ea4 encoder: fix computation of max coded buffer size (again). 
The previous fix was only valid to express the maximum size of the
macroblock layer, i.e. without any headers. Now, also account for
the slice headers and top picture header, but also any other header
we might stuff into the VA coded buffer, e.g. sequence headers.
