93a0682b1d ffmdec: limit the backward seek to the last resync position
If resyncing leads to the same position as previously, it will again
lead to a resync attempt, resulting in an infinite loop.

Thus don't seek back beyond the last syncpoint.

25b8d52fdd avformat/rm: limit packet size
The chunk size is limited to 0xFFFF (written by avio_wb16), so make
sure that the packet size is not too large.

Such large frames need to be split into slices smaller than 64 kB, but
that is currently supported neither by the rv10/rv20 encoders nor the rm
muxer.

av_add_index_entry() can fail, for example because the parameters are

happen with corrupted files.

The second hunk is just for robustness. Just in case functions like
ff_reduce_index() remove entries. (Not sure if this can actually
happen.)

0ce35b8ce8 mov: Fix negative size calculation in mov_read_default().
The previous code assumed if an atom was marked with a 64-bit
size extension, it actually had that data available. The new
code verfies there's enough data in the atom for this to be
done.

Failure to verify causes total_size > atom.size which will
result in negative size calculations later on.
