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.

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.

This is a step toward targets declaring their deps in a sane fashion.
This change resolves cycles by forcing core to the root, then everything
in skia_lib pointing toward core as best possible, then everything
outside skia_lib depending on skia_lib for things in skia_lib. This
prevents double definitions where a symbol is provided by both the
skia_lib shared object and and a statically linked component of skia_lib.

Need to avoid linking in .a things which are already provided by .so things.

This is a step toward targets declaring their deps in a sane fashion.
This change resolves cycles by forcing core to the root,
then opts, ports, and utils depending on core, then everything else.
We will need some other change to resolve the fact that
core, opts, ports, and utils depend on each other and other targets which
depend on them. Outside of these targets, things look ok.

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.
