Reason for revert:
Need to somehow get access to encoders in chrome -- link error on the roll since SkImageEncoder is not built as part of chrome.

Reason for revert:
This CL appears to be breaking the pictureshader, pictureshadertile and tiled_picture_shader GMs on the iPad4 and the N7. The artifact is black rectangles.

The test "nullptr == fBlockMemory->fHead->fNext" tests that
all of the data is in one block, but it is also necessary to
test "fBlockMemory->fHead" to ensure that there is a first
block with data in it.

One side effect is that the SkShader's (or implicit shader's) fragment processor is responsible for the transition from an unpremul paint color to a premul color.

To avoid breaking existing SKPs, add a deserialization stub which
unflattens SkBitmapSource records to SkImageSources.

The Registrar class is unnecessary, as SkFlattenable factory
registration is now handled via initialization routines that can just
call the Register function directly.
Also, no need to lazily initialize gCount to 0, as initializing an int
to a constant value does not require dynamic initialization. (C++
actually guarantees zero initialization of global ints anyway, but
existing practice in Skia appears to favor the explicit "= 0").
Relatedly, this requires removing the unused/unimplemented
SkLayerDrawLooper::MyRegistrar class. And removing that allows Clang
to realize that SkLayerDrawLooper::fTopRec is unneeded too, so remove
that too to squelch the compiler warning/error.
This doesn't change any public API.

This implementation improves performance of SkMutex acquire / release pair from 42ns -> 13 ns.
SkSharedMutex and SkSpinlock have the same performance.
It also removes specialized windows and linux/mac code.

These tests were isolated from their respective minimized test cases.
The tests work fine and pass path ops internal validation;
hopefully some more intensive x-san or valgrind test will help
isolate the bug.
Sheriff, please revert if it fails and I don't get to it first.

The last parameter of CTFontCreateWithGraphicsFont (CTFontDescriptorRef
attributes) *must* be nullptr. If non-nullptr then with fonts with
variation axes, the copy will fail in CGFontVariationFromDictCallback
when it assumes kCGFontVariationAxisName is CFNumberRef which it quite
obviously is not.

Blocking dev builds, just removes code.

Motivation: I want too finalize this API before working on the more
complex problem of adding XMP metadata for PDF/A.

SkBitmapRegionDecoderInterface provides an interface
for multiple implementations of Android's
BitmapRegionDecoder.
We already have correctness tests in DM that will enable us
to compare the quality of our various BRD implementations.
We also need these performance tests to compare the speed
of our various implementations.
