9b8583dd1f GN: misc
- Use options' template pattern for opts too.
  - Simplify opt's and options' configs... they should all be the same.
  - When building a static-library component in our GN environment (i.e. libskia.a),
    make it a complete static lib, fully containing its transitive deps.
  - It has not proved useful to override ar.

c095df55e8 GN: guard tools (except fiddle) by skia_enable_tools.
Our tools use third-party libraries pretty freely, some of which may not
be available in other GN environments (e.g. Fuchsia).  Most can also not
function when Skia is built as a shared library.

fiddle stands alone as the exception to both those points: it depends on
only Skia, and works fine with both a shared or static library.

So guard everything but fiddle with this flag skia_enable_tools, disabled
when we're building for Fuchsia or when we're build a shared library.

This CL has a couple of little tweaks to Fiddle to keep it working:
  - divorce it from :tool_utils, instead just building SkForceLinking.cpp itself;
  - fix up a buggy rebase_path() that was accidentally working when we depended
    on :tool_utils;
  - drop test_only: it now only requires production-code dependencies.

The SkImageEncoder Create* methods need to be SK_API if we want SkForceLinking
to work across .so's.  Without this, SkForceLinking needs to be part of Skia; it
can't be part of the application using Skia.

The rest is mostly just a re-indent under if (skia_enable_tools),
courtesy of gn format.

eb3c425f1b GN: make libwebp an optional dependency
This will be handy for folks who don't have libwebp, like Fuchsia.

I convinced myself that this is done right by:
  - building in all three modes (default and explicitly set both ways);
  - looking at verbose Ninja logs to see the presence/lack of SK_HAS_WEBP_LIBRARY;
  - running dm -m Codec, which passes with libwebp and segfault without it.

If this is viable, I intend to make all third-party dependencies optional
and follow this pattern.  :skia should link and degrade gracefully without
any of //third_party.  It's okay for tools to have hard third-party
dependencies; we just need them to get past the `gn gen` stage without them.

0a8efd7355 GN: _turbo -> -turbo to match Fuchsia
We might as well match the folks who are using our GN files now.

We've got plenty of strategies in our pocket for when we try to move Chrome
onto our GN files (and who knows, there may be even a new better way by then):
  * Same sort of rename in Chrome's third_party
  * Aliased targets via //build/secondary in Chrome.
  * Indirection via build_overrides

5259da5377 GN: gpu support in tools
If you want to try this out, the DOCS_PREVIEW link is a quickstart.

Are the GrGLCreateNativeInteface_* meant to be part of Skia-the-library
or just used by testing tools?  I've got it written here as tool-only,
but we could easily move it to libskia if it's a thing we want to ship.

I'm honestly not sure I understand how this linked before without a definition
of GrGLCreateNativeInterface().  Or are there two, one real and one no-op
default with some sort of weak linking setup?  dlopen()?

ada5a44f3b GN: get echo-headers sources via exec_script
exec_script runs every time gn does, which is explicitly on every one of our
bot runs.  That should be enough to obviate the .git/logs/HEAD hack.

Easiest way to do this was to swap around find.py's argument order to allow
multiple search directories.  This is the root of all the .gyp changes.

This moves the blacklist into BUILD.gn, which I think is nice.
It expands it a little as we're now searching recursively, into include/gpu/vk
which we can't include safely without the Vulkan SDK.

8796ff1fbc Turn on flags to enforce SK_API.
These flags hide symbols that are not marked with SK_API when linked into a
shared library.  There's nominally no effect on static linking, but I'm
pretty sure the Mac linker takes some advantage of this too to run faster.

This makes component-build DM no longer link: it uses many non SK_API APIs.
Fiddle in contrast is just fine with our public APIs, so no need to restrict that.

It'll be fun finding out which of our other tools go which ways.

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.

e817ddf9b3 GN: polyfill is_fuchsia
I'll tell you what, I need to practice typing fuchsia out a few hundred
times...  I managed to spell it three different ways in this CL.

Plus, gn format BUILD.gn

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.

The xcode backend seems to work.  From here, we can start exploring how to handle other backends (cmake,Android make, Google3).  There are a couple things I want to try:
  - add another backend like vs or xcode to GN directly
  - intercept via a custom toolchain
  - reverse from ninja -t commands
That last option seems kind of fun.

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:
   - build: Chrome's GN configuration, and much more
   - buildtools: hashes for gn binary, pulled via hooks
   - tools/clang: hashes for Chrome's clang, pulled via hooks into third_party/llvm-build
It additionally symlinks tools/gyp to third_party/externals/gyp.  GN pulls some stuff from tools/gyp on Mac.

Have not yet tried building for Windows, Android, or iOS.
