4fab08c94f Optimize pure C unscaled yuv2rgb.
Aligning the tables reduces the amount of code generated on
e.g. ARM as the offset constant then has few enough set bits
so it can be encoded inside a single instruction instead of 2.
Ideally all should be declared aligned, but the DECLARE_ALIGNED
macros does not work with pointer tables, thus also reordered
the tables.

  swscale: provide a default scaler if none is set

Conflicts:
	libswscale/utils.c

The default is left at bicubic until someone has compared the scalers
properly speed and quality wise.

6b3ff6f91a swscale: provide a default scaler if none is set
Lanczos for general case, sinc for upscaling, Gaussian for
downscaling. According to current literature these scalers
should be the best quality-wise algorithms for each case.

01e3340fb6 swscale: make bilinear scaling the default
Before this commit, sws_init_context() failed with an error if no scaler
was explicitly set.

Defaulting to something reasonable is better behavior.
