The invalid free's may be fixed (by using posix_memalign()). Patch is not being
accepted upstream for some reason, but ok, won't bother for now.

The invalid memory accesses are a problem. The ffmpeg devs (Michael) tell me to
pad allocated data by allocating 8 extra bytes, so they can validly overflow
while reading the bitstream. That is gross if you ask me, but it works that way
for them (mplayer & co, see also
http://sourceforge.net/mailarchive/message.php?msg_id=11427473). That's the last
2 valgrind warnings. Seems to work fine oherwise though.
