Add flag to force demuxers to sort more strictly by dts.
This enables non interleaved AVI mode for example. Players that are picky on strict interleaving can set this. Patches to only switch to non intereaved AVI mode when the index is not strictly correctly interleaved are welcome. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
