This limits ABI issues in case libavcodec is linked to a libavutil with larger AVFrame
Which can happen if they are shiped in seperate binary packages and libavutil is upgraded
A cleaner alternative would be to replace them by pointers but this would likely cause
a small speedloss

This is a bit tricky, we allocate a correctly sized AVFrame but then only
copy the compile time AVFrame size, this is to ensure that user applications
which do not use the correct av frame API dont end with out of array reads.
Note, applications using the correct API have set extended_data and the
changed code will never be executed for them.

There should be no such bugs in ffmpeg, but merging it anyway
as its safer.
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The default get_buffer2() implementation (and possibly some
user ones) does not allocate edges when this flag is set, which may
expose bugs in some decoders. Until the 10 release is out, it is safer
to remove this part.

This ensures that theres just one AVFrame allocation function and libs dont
produce multiple AVFrame variants after a minor lib update
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
Its possible to implement this with a few lines less code but it then
would flip the order of the list and require registration of external
codecs to be done first, also it could break user applications due to
this. Thus to maintain ABI this slighty more complex solution is
used.
