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.

ID3v1 fields have a fixed size, and they are padded either with zeros,
or with spaces. Handle the latter case, instead of putting strings with
trailing spaces into the AVDictionary.

Based on a patch by Michael Niedermayer <michaelni@gmx.at>.

Reduce the chance of introducing a class of bugs quite hard to track.

On some video samples, VDA silently fails to decode frames and returns
kVDADecoderNoErr. Error out in these cases to avoid producing AVFrames with
empty planes.
