Compared to existing, common opensource H264 encoders, this can be
useful since it has got a different license (BSD instead of GPL).

Performance- and qualitywise it is comparable to x264 in ultrafast
mode.

Hooking it up as an encoder in libavcodec also simplifies comparing
it against other common encoders.

This requires OpenH264 1.3 or newer. Since the OpenH264 API and ABI
changes frequently, only releases are supported.

To take advantage of the OpenH264 patent offer, the OpenH264 library
must not be redistributed, but downloaded at runtime at the end-user's
system.

This is the order that the caller uses in the rest of the file.
Variables are modified to reflect the order above too and their
initialization is merged with their declarationt. No behavioral
change.

I think this turned out pretty terrible. There's no good way to add new
custom tags that write to AVFormatContext->metadata.

The previous code assumed if an atom was marked with a 64-bit
size extension, it actually had that data available. The new
code verfies there's enough data in the atom for this to be
done.

Failure to verify causes total_size > atom.size which will
result in negative size calculations later on.

Under abnormal conditions the item_count may exceed the max
allocation size on 32-bit systems, this causes the allocated
size to overflow and become too small for the given count.

Additionally, if av_reallocp() fails its allocation, the
fragment_index_count is not correctly decremented.

Ensuring further havoc may be wrought, the error code for
read_tfra() is not checked upon return.
