This CL is ugly but it:
removes the stored SkGpuDevice back pointer from GrTextContext (at the cost of passing more parameters)
moves SkGpuDevice::internalDrawPath to GrDrawContext::drawPathFull
Unfortunately, the GrTextContext-derived classes still need the SkGpuDevice for filterTextFlags calls but I will try removing that in a separate CL.

There was a bug in onSkipScanlines where NULL was being passed instead of the SrcRow to png_read_rows.
This caused SkipScanlines to appear to be skipping, as fCurrScanline was updated and SkipScanlines returned success, however png_read_rows was not actually reading anything, and no lines were skipped.

This patch addresses two issues:
1) Textblobs with abandoned strikes were not properly regenerating.
2) Provided by ericrk - GrTextBlobCache removed blobs from |fCache| during freeAll, but left
potentially released blobs in the |fBlobList|. We now remove these from
|fBlobList| as well.

This is mainly a mechanical CL. There were some fiddly bits in GrContext.cpp where it no longer had access to the GrDrawTarget (and had to use the new GrDrawContext).
I've converted GrAARectRenderer & GrOvalRenderer into static classes so I could stop allocating them.

This fixes two issues: If gyp is run with the CXX and CC environment
variables set, it will produce different ninja build files.
sync-and-gyp now tracks the values of those variables; if they change,
re-run gyp.
Secondly, we introduced find.py, which is used inside gyp files. If
the contents of certain directories changes, gyp should be re-run. So
now we track those directories too.

Do not create a GrGLPath when loading glyphs with the driver and creating
GrGLPathRange based on those. The path would be inserted to the GPU
resource cache and then immediately be released.
Instead, just init the first path object of the path range as the
template.

If we include Sk4px.h, SkPMFloat.h, or SkNx.h into files with different
SIMD flags, that could cause different definitions of the same method.
Normally that's moot, because all the code inlines, but in Debug it tends not
to. So in Debug, the linker picks one definition for us. That breaks _someone_.
Wrapping everything in a namespace {} keeps the definitions separate.
Tested locally, it fixes this bug.

This code is not yet enabled in Chrome, so shouldn't affect the roll.

Removes the runtime logic used by PorterDuffXferProcessor to decide
blend coeffs and shader outputs, and instead uses a compile-time
constant table of pre-selected blend formulas.
Introduces a new blend strategy for srcCoeff=0 that can apply coverage
with a reverse subtract blend equation instead of dual source
blending.
Adds new macros in GrBlend.h to analyze blend formulas both runtime.
Removes kSetCoverageDrawing_OptFlag and GrSimplifyBlend as they are no
longer used.
Adds a GM that verifies all xfermodes, including arithmetic, with the
color/coverage invariants used by Porter Duff.
Adds a unit test that verifies each Porter Duff formula with every
color/coverage invariant.
Major changes:
* Uses a reverse subtract blend equation for coverage when srcCoeff=0
(clear, dst-out [Sa=1], dst-in, modulate). Platforms that don't
support dual source blending no longer require a dst copy for
dst-in and modulate.
* Sets BlendInfo::fWriteColor to false when the blend does not modify
the dst. GrGLGpu will now use glColorMask instead of blending for
these modes (dst, dst-in [Sa=1], modulate ignored for [Sc=1]).
* Converts all SA blend coeffs to One for opaque inputs, and ISA to
Zero if there is also no coverage. (We keep ISA around when there
is coverage because we use it to tweak alpha for coverage.)
* Abandons solid white optimizations for the sake of simplicity
(screen was the only mode that previous had solid white opts).
Minor differences:
* Inconsequential differences in opt flags (e.g. we now return
kCanTweakAlphaForCoverage_OptFlag even when there is no coverage).
* Src coeffs when the shader outputs 0.
* IS2C vs IS2A when the secondary output is scalar.

- Once in SkXfermode as usual to pick up compile-time SSE and NEON
- Once in SkXfermode_arm_neon to pick up run-time NEON
This allows us to start cleaning up SkXfermode_arm_neon as we've done
for SkXfermode_SSE2. I'm saving this catharsis for a day when I need it.
The Sk4px xfermodes are generally faster than the existing NEON procs,
so this should also have the side effect of a perf win there.
This means our new Plus-AA code works for runtime NEON too.
