3965825b97 Check libpng directly into third_party/
With this change, the CMake build, which does not use DEPS to sync
external projects, is able to build and use the same version of libpng
that is used in other builds.

This will allow all platforms (including Google3 CMake build) to test on
the same version of libpng, so we do not need to make SkPngCodec support
all versions of libpng.

- Update CMakeLists.txt to use the checked in libpng.
- Check in libpng version 1.6.22rc01
- Update README.google
- Replace our old LICENSE file with the latest one from libpng

740668d907 Update libpng to 1.6.22beta
Intel SSE filter optimizations have been upstreamed.  Let's test on
the upstream version (which we can use in Android).

b747b90501 Remove dependencies on Android's forked decoder libraries
Disable SkImageDecoder's code which relies on Android's customized
libpng and libjpeg. Build standard versions of libpng and libjpeg-turbo
everywhere. The SkImageDecoder code has been replaced with SkCodec, which
can decode subsets using standard library APIs

a5114d7f26 Have DM manually encode its .png outputs.
This eliminates some variability on various axes: different PNG encoders, different libpng versions, different formats (RGB, indexed), different unpremultiplication, different sRGB tags.

b2a6fe7976 Enable both static and dynamically linked libpng
All platforms except android are configured to use the statically linked copy
of libpng. Android uses the system provided dynamic copy for SkImageDecoder
and the static copy for SkCodec. The exception being android framework builds
that currently use the dynamic copy everywhere.

This CL also enables NEON optimizations for libpng.

ac813d8a12 Try ARMv7 and NEON for Daisy.
I think Daisy's color order problems are in non-NEON ARM assembly.
NEON might actually be fine.

f24f2247c2 Add SkCodec, including PNG implementation.
DM:
Add a flag to use SkCodec instead of SkImageDecoder.

SkCodec:
Base class for codecs, allowing creation from an SkStream or an SkData.
An SkCodec, on creation, knows properties of the data like its width and height. Further calls can be used to generate the image.
TODO: Add scanline iterator

SkPngCodec:
New decoder for png. Wraps libpng. The code has been repurposed from SkImageDecoder_libpng.
TODO: Handle other destination colortypes
TODO: Substitute the transpose color
TODO: Allow silencing warnings
TODO: Use RGB instead of filler?
TODO: sRGB

SkSwizzler:
Simplified version of SkScaledSampler. Unlike the sampler, this object does no sampling.
TODO: Implement other swizzles.

Requires a gclient sync to pull down libpng.

f84722e477 Build Skia for a bare-bones embedded Linux system.
Motivation:

    I have downloaded a barebones Linux system built for 64-bit ARM
    from linaro.org and a ARMv8 Foundation Model from arm.com to run
    it on.  This will let us build and test Skia on ARM64 before we
    aquire hardware to allow that.  This CL introduces the changes to
    the build files necessary to build Skia on a barebones embedded
    Linux system.  I tested it with the aarch64 GCC compiler provided
    by linaro.org.

Changes:

    Add a "barelinux" target_os for the DEPS file.  Add an optional
    git download of zlib.

    Changes to gyp files: these changes abstract out libpng, libz, and
    giflib so that images.gyp doesn't know whether they are static or
    dynamically linked.  I also add the variables skia_giflib_static,
    skia_libpng_static, skia_zlib_static, and skia_freetype_static,
    all of which default to false but when set to true will override
    the behavior of the giflib, libpng, zlib, and freetype build
    targets to require them to build statically.  Also, the
    skia_no_fontconfig variable turns off use of the fontconfig service.

	Scripts in platform_tools/barelinux/bin:

    arm64_download - this script downloads the Linaro's ARMv8 Aarch64
	toolchain and minimal embedded Linux system as well as ARM's
	foundation model.  The required files are mirrored on Google
	Cloud.  The script then starts a emulated Arm64 Linux system in
	the background.  After the boot is complete, you can SSH into the
	system at port 8022 via user@localhost.  The SSH key will be
	downloaded into the working directery as well.

	download_deps - Uses gclient to download Skia's dependencies for a
    bare Linux system (the normal dependecies plus giflib, libpng, and
    zlib.)

	barelinux_make - this script builds a version of skia that does
    not depend on external libraries, perfect for putting in an
    embedded system running Linux.  Assumes you have run download_deps
    first.

To test:
    To build a barelinux target, use the barelinux_make script.

    To build for a armv8 system: skia_arch_type=arm arm_neon=0 armv7=1
    armv8=1 arm_thumb=0 skia_arch_width=64 and set the CC and CXX
    variables to point at the cross-compiler downloaded by
    arm64_download.
