Previously, SkGifCodec treated an error in the LZW data as incomplete,
since we can still draw the partially decoded image. But a client doing
incremental decodes needs to distinguish this from truly incomplete
data. In the case of an error, the client should not attempt to provide
more data and decode again.
Add kErrorInInput, and return it when SkGifCodec sees a fatal error.
Treat it the same as kIncompleteInput when it comes to filling and DM.

my tests run ~14% faster.
- Split out gradient shaders from image shaders. new compilation
unit: SkPDFGradientShader
- Common functions InverseTransformBBox and PopulateTilingPatternDict
moved to SkPDFUtils
- Split SkPDFShader::State into image and gradient structures.
- SkPDFCanon is now a simpler structure, with no logic of its own.
I am considering just moving all of its fields into SkPDFDocument
- SkPDFShader::State (the image/fallback shader) now is POD, making
the use of a hashmap for canonicalization straightforward.
Formerly, we used a linear search.
- Do not bother trying to canonicalize the falback image shader.
- SkPDFGradientShader::Key is not POD; comparison of two objects
requires looking at the contents of two variable-sized arrays.
We now pre-calculate the hash of the arrays using SkOpts::hash and
store a hash for the object in the fHash field.
Using that hash, we can now canonicalize using a hashmap instead
of a linar search!
- several static functions renamed to follow style guidelines
- stop using codeFunction function pointer; I find that less
clear than it could be.
- operator==() for SkPDFShader::State and SkPDFGradientShader::Key is
now much simpler and can now be inlined.
- SkArrayEqual template in SkPDFUtils.h
No change to PDF output.

Gaussian blur filter will interpolate value by using out of bounds
coords, which is 0. This makes it appears darker near the bounds in the
blurred images. There are two issues: 1) when downsampling and
upsampling, we should use GrTextureDomainEffect kClamp_Mode to clamp
the texture coords to the bounds; 2) during Gaussian blur, we need to
clamp to texture bounds.

From the bug it looks like a null fragment processors may be getting into the processor set. This CL tries to plug any gaps in our fragmentProcessor handling.
The only real substantive part to this CL is the addition of some "if (!fp) { return nullptr; }" blocks.
Everything else is just to add chokepoints for processor allocation.
