Summary: 3:2 pulldown detection fails with bottom field first

Initial Comment:
The tvtime plugin fails to detect and reverse 3:2
pulldown when the video is encoded as interlaced frames
with top_field_first=0.

The algorithm used appears to assume top_field_first=1.

Here is an example stream (4.9MB):

http://janx.org/bottom_field_first_3-2_pulldown.vob

This example has 3-2 pulldown, so tvtime should detect
it and enter film mode. This does not happen.

all tvtime code used to assume tff=1. 
i already fixed the deinterlacing algorithms to correctly
handle tff=0 (xine-lib rc4), now we probably need to fix the
pulldown detection as well.
