By default, a demuxer's read_close function is not called automatically if an error happens when reading the header; instead it is up to the demuxer to clean up after itself in this case. The mov demuxer did this by calling its read_close function when it encountered some errors when reading the header. This commit changes this by setting the FF_FMT_INIT_CLEANUP flag so that mov_read_close() is automatically called when an error happens when reading the header. (Btw: mov_read_close() is not idempotent: Calling it twice is dangerouos, because MOVContext.frag_index.item will be av_freep'ed, yet MOVContext.frag_index.nb_items won't be reset. So the calls to mov_read_close() have to be removed before the switch to freeing generically.)
