Find the closest previous frame to the timestamp, in e_old index entries.

Searching for just any frame / just key frames can be controlled by last argument 'flag'. Returns the index of the entry in st->index_entries if successful, else returns -1.

Add index entry with the given values, to the end of st->index_entries.

Returns the new size st->index_entries if successful, else returns -1.

This function is similar to ff_add_index_entry in libavformat/utils.c except that here we are always unconditionally adding an index entry to the end, instead of searching the entries list and skipping the add if there is an existing entry with the same timestamp. This is needed because the mov_fix_index calls this func with the same unincremented timestamp for successive discarded frames.
