Attempt to take over all *SAN builds.
MSAN has a lot of coordination required between gn/BUILD.gn and gn_flavor.py.
I'd like to follow up to move more of this into gn/BUILD.gn, to make it easier
to use locally.
The compile steps should be much faster now. We no longer build CMake
and Clang for every run, instead using the clang_linux CIPD package. This
removes the need for all the third_party/externals/llvm/... dependencies.
Similarly, since we're using the clang_linux package, we no longer depend
on Chrome's Clang, and thus no longer need to sync chromium on these bots.
Instead of packaging up MSAN libraries and llvm-symbolizer in the compile
output, I have the test / perf bots also depend on the clang_linux package.
These do not vary from build to build.
No more need for the xsan.blacklist -include hack: Clang, GN, and Ninja
all track changes to xsan.blacklist without our help.
This has the incidental effect of upgrading the compiler used by *SAN
bots from Clang 3.8 to Clang 3.9.

With this version, it's now exposing GL_EXT_color_buffer_half_float, but
it's (incorrectly) using GL_HALF_FLOAT rather than GL_HALF_FLOAT_OES.
In addition, release builds were crashing in EGLImageTest due to an
apparent disagreement about calling convention on function-pointer to
exported symbol. There is a proper typedef for that in one of their
headers, but I can't seem to include it without creating more problems,
so I just fixed the decoration on our local typedef.
With those changes, all tests pass, and (on my Windows machine), all
GMs and SKPs produce identical results vs. master in angle and angle-gl.

This sketches out what a world without Chrome's GN configs would look like.
Instead of DEPSing in build/, we now host our own gypi_to_gn.py.
The symlink from skia/ to . lets us run gclient hooks when the .gclient file is in the directory above skia/ or inside skia/. That means we don't need gn.py anymore.

What we've got here is a little GN MVP. It's lacking any knobs and doesn't yet build anything but libskia, zlib, libpng, and libjpeg-turbo. I've been hopping back and forth between Linux at work and Mac at home. These seem to be at least partially working, enough to build and run cmake/example.cpp.

This tries to piggyback on Chrome's GN setup as much as possible. Chrome's got quite a lot figured out, and we're basically required to do this if we want to have a single GN build system shareable by Chrome, our bots, and other clients.
This pulls in some new DEPS:

- Add CMake v3.3.1 (latest) to DEPS.
- Add cmake/bot-cmake.sh to bootstrap CMake then build Skia using that.
Works on my Mac and Linux box, both with no system CMake installation.
CMake will be ~100M on disk. The first bootstrap takes a couple minutes,
and a no-op re-run of bot-cmake.sh takes 15-20 seconds. I thought about
having bot-cmake.sh fetch CMake instead of DEPS, but I'm not sure I can
handle updates, etc. as robustly as it can.
This will only work on Linux and Mac. CMake requires an older CMake on
Windows. It doesn't have an equivalent ./bootstrap there. Will have to
think about how Windows bots will work!

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.

Unfortunately, since we can only build ANGLE by including a gypi, and since
gyp cannot process includes conditionally, we *have* to have a build_angle.gypi
file in the third_party/externals/ANGLE/src directory. We could do a hack
where we create an empty gypi if ANGLE is not checked out, but for now we just
check out ANGLE on all platforms.
