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.

This patch adds minimal support for dynamic ARM NEON support,
i.e. the ability to probe the CPU at runtime for NEON and
provide alternate code paths when it is available.
- Add include/core/SkUtilsArm.h, which declares a few helper
macros (e.g. SK_NEON_ARM_IS_DYNAMIC), plus the handy
function 'sk_cpu_arm_has_neon()' which returns true if
the target CPU supports the ARM NEON instruction set.
Note that the header is in include/core/ because it will
have to be included from NEON-specific code under src/code/
It would probably be more logical to put it under include/opts/
instead, but this would require moving all the NEON-specific
stuff under src/code/ into src/opts/, which is not trivial
due to the way the code is currently architected.
- Add src/core/SkUtilsArm.cpp which implements
'sk_cpu_arm_has_neon' for ARM-based Linux systems, only
when SK_NEON_ARM_IS_DYNAMIC is true.
(For other cases, 'sk_cpu_arm_has_neon' is an inline function
that returns a constant 'true' or 'false' value).
There is no user-level accessible CPUID instruction on ARM,
so do all CPU feature probing by parsing /proc/cpuinfo.
This is Linux-specific.
For Debug build types, the CPU probing result is printed
to the Android log (or Linux command-line) for easier
debugging.
- Create a new 'opts_neon' target (static library) which shall
contain all the NEON-specific code paths for the library.
This is necessary because -mfpu=neon impacts also non-scalar
code. Just like with -mssse3 on x86, we can't build the rest
of the library with this flag.
Note that for now, we only include memset16_neon and
memset32_neon in this library.
- Modify opts_check_arm.cpp to implement SK_ARM_NEON_IS_DYNAMIC
properly.
Compared to a 'xoom' build, the only difference is the use of
NEON-optimized memset16/32 functions. Later patches will move
more NEON-specific code paths to 'opts_neon'.

The current impl for SkFlattenable read/write buffers is
that they extend from SkReader32 and SkWriter32, but that
dependency must be abstract if we are to add any other
serialization format.

Do this, rather than including common.gypi explicitly in all our gyp files, so that gyp files we use but do not maintain (e.g., third_party/externals/libjpeg/libjpeg.gyp) will include common.gypi too.
