When the input frames contain side data, it will accumulate endlessly in
the coded frame, as av_frame_copy_props will append any new side data.

Fixes ticket #5799.

This will simplify the de-MpegEncContextualization.

This avoids unused variable warnings after the next version bump.
Also drop a trace level av_log() call that is in the way.

The openh264 option is dropped altogether since it is just a fallback
for -max_nal_size anyway.

Add an allowed value to the private options for frame_skip_cmp which
seems to have been forgotten, but perfectly working.

The libvpx frame dropping feature uses one of such option
(frame_skip_threshold) without the other three. For this reason rename
the option to something more consistent with the other libvpx variables.
