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.

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

About 9x faster than Murmur3 for long inputs.
Most of this is a mechanical change from SkChecksum::Murmur3(...) to SkOpts::hash(...).

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()?

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.

These files are now so badly misnamed that it is causing problems.
The original files are kept as shells until Chromium and PDFium can
be updated. After Chromium and PDFium builds are updated, the old
files will be removed and the cmake and bzl builds will be updated.

SkForceLinking wasn't force-linking the WEBP encoder, or any encoder.
(The others must be explicitly used.)
This should help the GN Debug Perf bots progress past

Add nanobench, and while we're at it monobench to show off how cool
source_sets are... the bench files are only built once then linked
into both binaries. With GYP we build them twice. :/ Same deal
for GMs between nanobench and DM... build once, link twice.
nanobench uses SkImageEncoder to encode its .pngs, which requires
we link in the image encoders, which requires we get them all in.
That's the bulk of this.

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.

This builds, links, and runs on Linux. Have not tried Mac.
I've tested is_debug={true,false} and is_component_build.
It's neat that the component build DM works, but it's also an indication I've missed an essential flag or two... it shouldn't work. :)
The GPU backend isn't working yet, but all the software configurations I've tried look good.
This fleshes out all the other parts of SkCodec too... I noticed we weren't able to decode gifs or webp.

- Make fiddle build on Mac (skipping GL).
- Now that we're building in SkCodec, we depend on libpng and libjpeg-turbo unconditionally, not just on Linux.
- Re-arrange third_party a bit so that our targets are Fuchsia/Chrome compatible.

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.
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.
