[FFmpeg-cvslog] a64multienc: Do not entangle coded_frame

[Vittorio Giovara]

ffmpeg | branch: master | Vittorio Giovara <vittorio.giovara at gmail.com> | Wed Jul 15 18:41:10 2015 +0100| [91767360d86ac786571593ab11c7291010ab3829] | committer: Vittorio Giovara

a64multienc: Do not entangle coded_frame

This change (and the following ones of the same kind) is mainly to
simplify wrapping this section with an #if FF_API block later on.

No functional changes are applied, the fields of the context coded_frame
fields are directly initialized, instead of keeping a reference to the
coded_frame itself.
