8079ba688c GN: add extra_cflags et al.
Adding flags to the end of cc or cxx is pretty useful, but these always end up
on the command line before the GN generated flags, thus setting defaults that
GN will override.

For full flexibility we want to be able to add flags after the flags GN has
added, so that custom flags can override _it_.

I've updated the Fast bots with an example here: if we said cc="clang -O3 ...",
that '-O3' would be overriden later by the default Release-mode '-Os'.  By
putting it in extra_cflags, we get the last word: our '-O3' overrides the
default '-Os'.

Another good use case is a hypothetical Actually-Shippable-Release mode.  Our
Release mode bundles in tons of debug symbols via '-g'.  libskia.a is about 10x
larger than it needs to be when built that way, but it helps us debug the bot
failures immensely.  To build a libskia.{a,so} that you'd really ship, you can
now set extra_cflags="-g0" to override '-g'.  You could set '-march' flags there
too, '-fomit-frame-pointer', etc.

There are lots of flags that won't matter where they end up in the command line.
To keep everything simple I've put them in extra_cflags with the rest.  This means
the only time we change 'cc' or 'cxx' in our recipes is to prefix 'ccache'.

d434b01c7e Roll GN: gn format is --in-place by default
As usual, might as well roll, and this new behavior is a small convenience.

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.

6be452c800 GN: only include headers in echo_headers.py
This keeps things like VIM .swp files out of skia.h.

5db44aa2aa GN: components as static library instead of source set
This also puts the .a in the top-level of the ouptut directory, just
like we do for .so files.  It's less required than for .sos, but it
does make it easier to find the .a.

f05c2c22a7 GN: add abbreviated versions of the command line as descriptions.
This should help make the bot logs a little easier to read.  (On the console
this wasn't much of a big deal, as Ninja auto-abbreviates when printing to an
interactive console.)

As usual, Ninja will print the full command when a task fails.

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.

7d10b9f6e6 GN: fixes for Mac
- 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 doesn't affect Chrome/Blink, so landing through the closed tree.

7fbfbbe8f4 Basic standalone GN configs.
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.
