Implement support for path rendering in Chromium through
CHROMIUM_path_rendering pseudo extension.
The extension defines a new pseudo-gl function,
BindFragmentInputLocation. This behaves similarly to the
BindUniformLocation pseudo-gl function. The idea is to assign fragment
input location to a fragment input before linking the program.

- supports kGray correctly
- avoid extra call to png_get_IHDR by storing the bit depth
- call transforms as needed
- checks for tRNS alpha value in RGB and GRAY color types

Some of this is transitive, like SkRecords.h used by SkMiniRecorder.h
used by (public) SkPictureRecorder.h.

This makes nanobench picture recording benchmarks somewhat useful again,
as opposed to all taking about 5us to run no matter the content.
ATTN Sheriff: this will probably trigger perf.skia.org alerts.

the bottom of the image. In our code before this patch,
this would result in cleanup code in onFinish() never being
called.
We can allow subclasses to take ownership of the
SkScanlineDecoder in order to make sure that it is
finished/deleted before deleting the decode manager.

Non-NV_path_rendering drivers should always return NULL context
for NVPR context type request. Fix this.
This was needed due to the previous patch trying to implement below:
NV_path_rendering drivers should return non-NULL context
for NVPR context type request, regardless whether path
rendering is actually supported or not. This is due to SAN
bots having older drivers and trying to run nvprmsaa config.

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.
Avoid failing interface creation even if nvprmsaaXX config is
requested but the driver is not recent enough. The SAN bots have
old driver, but try to run nvprmsaa16 configs. Instead, print
out a warning.

This patch ensures that when inverting a SkMatrix44, we handle small
floats properly. When inverted these can cause infinite values, but
still evaluate to true in an if condition.

All of the CodecSubset benches fail when the color type is
kIndex8. We need to pass a color table to allocPixels()
when we want to decode to kIndex8 or it will throw a failure.

The ~ means "don't run this". This keeps all the other bots running the code, skipping it only on the whiny TSAN bot.

This has the effect of using delay_copy() on every argument,
obviating the need for delay_copy() and, crucially, having
to remember to call delay_copy().
All these constructors are fully inlined, so we'll never pay
a penalty for passing small things by reference... the compiler
can see that and just pass by value.

Refactor separable varying location info to be stored in GrGLProgram
subclass GrGLProgram instead of storing it in GrGLPathProcessor.
Separable varyings are exactly analoguous to uniforms: they are inputs
to the shader program. Shader compile-time information about uniforms is gathered to
GrGLProgramBuilder. This information is the converted to link-time
information, uniform locations, when constructing the program. Separable
varyings need to have same lifetime model.
This is needed in the future to support path rendering in Chromium. The
Chromium pseudo-extension will expose program fragment input binding
function similar to uniform binding function. Thus the separable varying
locations need to be decided and bound before link, e.g. before
GrGLProgram is created. This will be achieved in further patches by
overloading GrGLProgramBuilder::bindProgramResourceLocations() in
GrGLNvprProgramBuilder.
