vf_bwdif's frame management logic is almost identical to that of yadif. The only difference is that it tracks the first and last fields in a sequence, and that requires slight changes to the common code.
Assuming it's reasonable to do that tracking even though yadif doesn't need it, we can then remove all the duplicated logic.
