fbc6d7fcf6 Make SkColor4f <-> SkColor skip sRGB conversion
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.

9e229233a6 update SkColor4f::FromColor() to preserve transfer function
This kills off some sRGB tables,
and lots of call sites can now use SkColor4f::FromColor().

It doesn't seem important to keep this test.

f1f1162273 remove append_from_srgb()
It's now no different than append(from_srgb).

16776dfb4b funnel all constant colors through append_constant_color()
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.

af06420cc1 Test sk_linear_to_srgb() less exhaustively in Debug mode.
It's pretty slow when not optimized... it can take ~5 minutes to run.
This makes it take ~2 seconds on my laptop.

566ea9b9fc Tune linear->sRGB constants to round-trip all bytes.
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.

Rounding is enough.  No need for an explicit clamp if the inputs are in range.

ac41bac40f Move sRGB <-> linear conversion components to their own files.
This makes them a little easier to use outside SkColorXform code.

I've added some notes about how best to use them and their eccentricities, and added a test.

Ultimately any software sRGB <-> linear conversion should funnel somehow through here.

e930459a18 Revert of Move sRGB <-> linear conversion components to their own files. (patchset #5 id:80001 of https://codereview.chromium.org/2128893002/ )
Reason for revert:
Monotonicity assert is failing on ARM.  (Different rsqrt() and invert() precision?)  Will investigate a bit tomorrow... might reland with the test TODO.
