Fixed-function NVPR codepaths were removed a while ago. Only NVPR API
version 1.3 (PathFragmentInputGen) was left working. Remove
backwards-compatibility code that was left behind.
Remove some NVPR API function typedefs that were left from initial
commits.
Remove PathCoords function pointer from GrGLInterface, it has
never been called and causes problems in the future, since it will
not be implemented in the Chromium pseudo extension.

HardLight, Overlay, Darken, and Lighten are all
~2x faster with SSE, ~25% faster with NEON.
This covers all previously-implemented NEON xfermodes.
3 previous SSE xfermodes remain. Those need division
and sqrt, so I'm planning on using SkPMFloat for them.
It'll help the readability and NEON speed if I move that
into [0,1] space first.
The main new concept here is c.thenElse(t,e), which behaves like
(c ? t : e) except, of course, both t and e are evaluated. This allows
us to emulate conditionals with vectors.
This also removes the concept of SkNb. Instead of a standalone bool
vector, each SkNi or SkNf will just return their own types for
comparisons. Turns out to be a lot more manageable this way.

It's possible this rarely breaks, but I do write ARMv8 code frequently
enough that it'll help prevent broken trees.

Modern processors support flush-to-zero and denormalized-are-zero
for floating point operations (with ARM NEON unable to disable them).
However, iOS on ARM is the only current system which defaults
processes to using both all the time. However, this is only iOS on
ARM, iOS on x86 (the simulator) does not. Correctly defining this
allows the math tests to run error free in the simulator.

On the n5 there seems to be an issue where negating a variable at the start
of an equation doesn't work. Moving the negated variable to a subtract at the
end works around the issue (as would multiplying by -1.0).
The main bug was caused by the -DaCub in the else if block, but I also
adjusted the else block to make sure the same issue doesn't appear there
at some later date.

There are a number of files with 'FontConfig' in their names which
just have to do with font configuration, but nothing to do with
the FontConfig project or even with each other. This clarifies
that these files deal with parsing for the Android font manager.

Start moving to a world where everyone provides surface properties.
Most notably this exposes a portion of SkSurfaceProps to the C API.

This CL continues cleaning up Skia's usage of SkSurfaceProps. It:
Removes the duplicate SkSurfaceProps object from SkImageFilter::Proxy.
Removes a dispreferred ctor from SkCanvas
Removes the initForRootLayer entry point from SkDevice (since the root device and the canvas should always have the same pixel geometry now).

Mostly this is about ergonomics, making it easier to do good operations and hard / impossible to do bad ones.
- SkAlpha / SkPMColor constructors become static factories.
- Remove div255TruncNarrow(), rename div255RoundNarrow() to div255(). In practice we always want to round, and the narrowing to 8-bit is contextually obvious.
- Rename fastMulDiv255Round() approxMulDiv255() to stress it's approximate-ness over its speed. Drop Round for the same reason as above... we should always round.
- Add operator overloads so we don't have to keep throwing in seemingly-random Sk4px() or Sk4px::Wide() casts.
- use operator*() for 8-bit x 8-bit -> 16-bit math. It's always what we want, and there's generally no 8x8->8 alternative.
- MapFoo can take a const Func&. Don't think it makes a big difference, but nice to do.
