avcodec: Add padding after the remaining AVFrames

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

http: restructure http_connect error handling path

The authstr memory allocations make it annoying to error in the middle
of the header setup code, so apply the usual C error handling idiom to
make it easier to error at any point.
