Every doc I've found about using Android's atomics says, "stop".
"* A handful of basic atomic operations. The appropriate pthread
* functions should be used instead of these whenever possible."
"... we recommend stopping from using these functions entirely. Very fortunately, GCC provides handy intrinsics functions that work with very reasonable performance and always provide a full barrier."
As far as I can tell, there's no code generation change here: both the __sync atomics and the android_ atomics use full memory barriers. (And now with this all unified, it'll be easier to get the real wins by switching everything to __atomic atomics, which are like __sync atomics but allow control over memory barriers.)

Split off from https://codereview.chromium.org/140503007/.
The eventual goal is to create our Android.mk from gyp. This patch
adds an option for skia_android_framework with the right settings.
The follow-up (https://codereview.chromium.org/140503007/) will
use scripts to create the final makefile.
gyp/android_deps.gyp:
Use different dependencies for the framework than for building Skia
normally.
gyp/android_framework_lib.gyp:
Like skia_lib, specifies the minimum needed for building Skia, in this
case for the framework.
gyp/common_conditions.gypi:
Add settings specific to skia_android_framework. In some cases this
means turning off flags and defines.
gyp/common.gypi
Turn off SK_DEBUG and SK_DEVELOPER when building for the framework.
This allows the framework to create a single makefile which can be
modified to add SK_DEBUG and SK_DEVELOPER as desired.
gyp/common_variables.gypi:
Add skia_android_framework.
gyp/core.gyp:
Don't depend on cpufeatures, and add the cutils library for
skia_android_framework.
gyp/freetype.gyp:
skia_android_framework-specific options:
Don't include freetype_static as a dependency.
Include the proper folders.
Include the android library.
gyp/images.gyp:
Don't export libjpeg as a dependency for targets that include images
for the framework.
Also reorder image decoders to match the Android order, leaving our
most commonly used ones last (and therefore first in the chain for
trying them).
gyp/libwebp.gyp:
Use the system webp when building for the Android framework. Specify
the correct settings for the framework.
gyp/opts.gyp:
Specify a default set of files to compile when there are no possible
optimizations.
gyp/pdf.gyp:
Add dependencies for Android framework.
gyp/zlib.gyp:
Include the zlib folder, and undefine SK_ZLIB_INCLUDE.

Add an option to SkCanvas to turn on path
ops when combining clips.
Allow Op() to use one of the input paths
as an output path.
Fix a bug in Op() when the minuend is empty
and the subtrahend is not (for difference).
Change the build to allow core to depend on pathops.

The new pixel ref behaves similarly to SkImageRef, with some key differences:
It does not depend on the images project.
It requires an SkImageCache, which handles allocation and caching of the pixel
memory.
It takes a function signature for decoding which decodes into already allocated
pixel memory rather than into an SkBitmap.
Add two implementations of SkImageCache: SkLruImageCache and SkAshmemImageCache.
Replace SkSerializationHelpers::DecodeBitmap with SkPicture::InstallPixelRefProc,
and update sites that referenced it.
SkBitmapFactory now sets the pixel ref to a new object of the new
class SkLazyPixelRef, provided it has an SkImageCache for caching.
Provide an option to do lazy decodes in render_pictures and bench_pictures.
SkPicture:
Eliminate the default parameters in the constructor.
If a proc for decoding bitmaps is installed, use it to decode any encoded
data in subpictures.
When parsing deserializing subpictures, check for success.
When serializing subpictures, pass the picture's bitmap encoder to the
subpicture's call to serialize.
Update BitmapFactoryTest to test its new behavior.

Notify the surface when the canvas draws into it, so it can invalidate the
cached image, and (if needed) perform a copy-on-write on the surface if it
was being shared with the image.

Refactor Picture and Pipe bitmap storage into common data structure
Update SkFlattenable buffers to be more modular.
This CL is an effort to stage the conversion to named
parameters for all SkFlattenable commands. This particular
stage only does the following two things...
1. Move flattenable buffers from SkFlattenable.h into
their own header.
2. Update and Add new read write methods for better clarity
and convenience.
