Our srgb_roundtrip_extended unit test has shown that our from_srgb and
to_srgb stages start to break down outside a range of about [-2,2], and
they appear to asymptote to roundtripping to y=8, not an identity y=x.
We'll continue to use these stages where we know ahead of time that
the inputs are all in [0,1], and otherwise fall back on ::parametric.
Guarded by SK_LEGACY_SRGB_STAGE_CHOICE.

The distinction between SkJumper and SkRasterPipeline used
to be important, but it's no longer. This CL moves everything
under src/jumper to the appropriate SkRasterPipeline file.

This lets us remove the old S32 functions, and fix a couple bugs.
I think this is a good first step to using SkColor4f for paint colors.

My next step is to change the uniform_color context to
struct {
float r,g,b,a;
uint32_t rgba;
};
so that it's trivial to load in both float and 8-bit pipelines.

I basically just ran a big 5-deep for-loop over the five constants here.
This is the first set of coefficients I found that round trips all bytes.
I suspect there are many such sets.
