Includes a libavcodec utility function to update a frame's side data.

Applications that have been linked against an older release of Libav and pick up
updated libraries experience segmentation faults because they pick up the new
libavfilter, which assumes AVFrames have been allocated by libavutil and thus
contain new reference-counting related fields. This will break for AVFrames that
have been allocated by old libavcodec.

All scheduled API changes are deferred to the next bump.

Commit 41578f70cf changed the LLS API, which was
called from libavcodec. Thus using an old libavcodec with a new libavutil will
break.

All scheduled API changes are deferred to the next bump.

Also bump libavcodec micro and add an APIchanges entry saying that
av_frame_* should now be used instead of the lavc AVFrame functions.

We will likely want to add new fields to it in the future, so this is
needed to avoid breaking ABI.

This can be optionally disabled whith the "output_corrupt" flags
option.  When in "output_corrupt" mode, incomplete frames are
signalled through AVFrame.flags FRAME_FLAG_INCOMPLETE_FRAME.

Also fix the typo in the last entry version.

Provide a clean way to manipulate packets.

The bitstream buffers are now private and freed by libavcodec. For
backward compatibility, the hold bitstream buffer pointer is left NULL
(applications were supposed to av_freep() it).

These help avoiding overflows and simplify error handling.

Mostly based on libavcodec's

It will be useful in lavfi, and could conceivably be useful to the user
applications as well.

Fixes Bug 378.

Removes an arbitrary hardcoded limit on the number of filters.

The caller needs to know what valid indices can be passed to
avfilter_pad_get_name/type.

This will be useful in avtools in the following commits.
Any other caller might also want to know this information.

Drop the unused opaque parameter from its signature.

It will be useful in the following commits.

Since this function adds a standalone filter to a filter graph and we do
not support creating such filters, there is no reason for this function
to exist.

Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.

We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

This is more consistent with the naming in the rest of Libav.
