plugins/avi/avi.c : now you can see avi over http (true interleaved

file only), and seek is allowed (but with great unsynchronisation,
and sometimes it fails). But in order to make it working, I have to
limit the number of bytes I read at a time. It's strange since in
previous version of vlc, I don't need to do that ... ( it segfaults in
input_SplitBuffer but not always on the same frame )
