Niklas Haas 47f89ea88b swscale: explicitly track if a context is "legacy" or not ...

The legacy API is defined by sws_init_context(), sws_scale() etc., whereas
the "modern" API is defined by just using sws_scale_frame() without prior
init call.

This int allows us to cleanly distinguish the type of context, paving the
way for some minor refactoring.

As an immediate benefit, we now gain a bunch of explict error checks to
ensure the API is used correctly (i.e. sws_scale() not called before
sws_init_context()).
