wmv==asf but renamed...

aviplay reads the whole file (and adds each frame duration and counts
frames). it take stoo long, and i see no sense of implementing it only for
seeing how long is it...

i dunno how win media player knows it, but they probably has the .asf specs :)
i think there is some info in asf header about this, but we have only a
partially reverse-engineered doc from avifile author, what doesn't contain this info.
you can play with the unknown fields in the asf blocks, check asfheader.c!
tell me if you found it.
