The old code requires that include/config/SkUserConfig.h exists,
to ensure that it gets copied into Android's
include/core/SkUserConfig.h when we do a merge. However, if a
developer wants to make changes and rerun the script, they
should not have to recreate include/config/SkUserConfig.h just
to rerun the script. By default, allow the original to not
exist and just skip the copy.
Update tests to pass. Also add tests to support this use case.
Make gyp_to_android.py executable.

Aarch64 support
This change contains the necessary modifications to have Skia build and
run properly on an ARMv8 processor in aarch64 execution state.
Here's a list of the changes:
- add an arm64 target to the build system + SK_CPU_ARM64 flag
- MatrixTest was failing when built in Release mode. Fused MAC
instructions were generated which made some intermediate results
more accurate. As the test relies on result comparison, the more
precise results when compared to others led to a gap bigger than
what was tolerated. As I don't know if some actual skia code relies
on results being comparable, I've disabled fused MAC instruction
with -ffp-contract=off for arm64.
- Modify include/core/SkOnce.h to have barriers work.
- SK_CPU_ARM64 implies SK_ARM_NEON_MODE_ALWAYS.
- use existing Xfermode optimisations with modifications that can be
removed in the future when toolchains are ready. Also save a few
instructions is two Xfermodes (will apply to ARM too).
- use existing SkBoxBlur and SkMorphology optimisations.
- use existing SkBlitMask optimisations
- use existing BitmapProcState and Convolution optimisations.
Future changes will include:
- Blitters (only partialy merged upstream)
- SkUtils (there's little value in sending asm optimisations without
having them benchmarked on real hardware).

Since we never want to build with the fake SkUserConfig.h files
(they're only there for testing), change their name to
SkUserConfig-h.txt. Now the housekeeper will ignore it.
Also, update the generated version to match what the housekeeper
wanted. It wants my tabs to be 4 spaces, so change my tabs to 4
spaces!

Generate SkUserConfig.
Include arm64 as another build flavor.
Add tests.
gyp/common_conditions.gypi:
Add conditions for Android framework. These will get written into the generated SkUserConfig.
include/core/SkUserConfig.h:
Generated version that will ultimately be checked into Android (but not here).
platform_tools/android/bin/gyp_to_android.py:
Generate SkUserConfig.
Add arm64 (note that arm64 is not currently respected by our gyp files, so it results in use _none.cpp for the various opts).
Reset the common defines, which are now passed to the generated SkUserConfig.
platform_tools/android/gyp_gen/generate_user_config.py:
New script to generate SkUserConfig.h.
platform_tools/android/gyp_gen/gypd_parser.py:
Fix a lint error (unused import).
platform_tools/android/gyp_gen/makefile_writer.py:
Append any remaining DEFINES to LOCAL_CFLAGS (previously this was done during parsing).
Add a warning for arm64 (corresponds to downstream Android.mk).
platform_tools/android/gyp_gen/vars_dict_lib.py:
Add OrderedSet.reset().
Add DEFINES to VarsDict.
platform_tools/android/tests/expectations/:
Add and update expectations files.
platform_tools/android/tests/generate_user_config_tests.py:
New test for generate_user_config.py
platform_tools/android/tests/inputs/SkUserConfig.h:
Input to the new test, so we don't have to update the expectations each time the real SkUserConfig.h changes.
platform_tools/android/tests/makefile_writer_tests.py:
Add a way to rebaseline test_write_local_vars, which has changed.
Refactor EXPECTATIONS_DIR and compare_files into a separate file for sharing with generate_user_config_tests.py.
platform_tools/android/tests/utils.py:
Common code for tests.
platform_tools/android/tests/var_dict_tests.py:
Use a for loop to test the new key (DEFINES) and future proof this test to test any new keys in the future.

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.

android_ninja {tests,bench,gm,bench_pictures,render_pictures} all build and run
fine. They build so fast I thought maybe they were broken.
Note that android_ninja with no argument is failing:
ninja: Entering directory `out/config/android-arm_v7_thumb/Debug'
ninja: error: 'lib.target/libSampleApp.so', needed by 'android/libs/armeabi-v7a/libSampleApp.so', missing and no known rule to make it
Will look into this.

Now that CreateFromStream is used, check for NULL rather than
looking at width and height (prevents a crash on an invalid SKP).
Unref the picture when done with it.
Remove the member variable for picture, since it is only accessed
inside the one function.

Currently we use gsutil to download ndk. However, it requires extra
steps to install, and is not convenient to configure (several steps to
enable Google storage), especially for developers behind proxy (need to
set config of boto). Chromium provides some python scripts to help
download nacl toolchains that can meet this need well. So this patch
basically borrows two python scripts from there, and makes some
according changes to remove the usage of gsutil. With new script, we may
also implement some advanced features, such as hash check, so that the
download would be more intelligent.

This CL is the first step in a series needed to move the
android directory into trunk. After the copy we will update
GYP and DEPS to point to the new location and only then
remove the original directory.
