avformat/internal: Add ff_get_frame_filename

It's similar to av_get_frame_filename2 but with int64_t number
support. Make av_get_frame_filename* a wrapper over
ff_get_frame_filename.

avformat/mov: don't return the latest stream when an item stream is expected

Otherwise, things like ICC profiles as read from the colr box meant for an item
with no stream (like a grid) may end up being added to the wrong stream.
