vf_rotate: support all multiples of 90 degrees
This couldn't rotate by 180°. Add this, and also make the parameter in degrees, instead of magic numbers. For now, drop the flipping stuff. You can still flip with --vf=flip or --vf=mirror. Drop the landscape/portrait stuff - I think this is something almost nobody will use. If it turns out that we need some of these things, they can be readded later. Make it use libavfilter. Its vf_transpose implementation looks pretty simple, except that it uses slice threading and should be much faster.
