Updated patchset. Patches 1-2 could maybe be squashed
The end result of these patches is that fragmented files probe much
faster over HTTP. The final patch is just a small optimization to
movenc

Subject: [PATCH 1/6] lavf/mov: Always try to parse mfra if file contains moof
boxes
If the demuxer succeeds it will set c->frag_index.complete which will enable mov_read_default() to stop earlier.
This is useful for reducing the number of seeks in fragmented MP4 files.
