This has a few advantages:
- We can track dependencies more precisely
- ninja can assemble things in parallel as they're ready rather than
sequentially all at once.
- It is easier to customize SDKs depending on target platform, e.g.
Fuchsia.
This CL also has a number of cleanups:
- Defining is_fuchsia and is_fuchsia host so we don't always have to check
- Piping through toolchain overrides in more places
- Fixing bugs in copy_tree.py, not using list_files.py, which is broken on Windows

Flutter uses the same clang toolchain as Fuchsia. This CL puts Dart
on that toolchain, as well. This roll should entail no changes to
glibc version requirements on Linux.
The Fuchsia buildtools distribute clang-format with the toolchain
rather than separately, so this CL introduces forwarding scripts
that are copied to the right place under //buildtools.
This CL sets the default for the number of workers in //tools/gn.py
to 1, as the newer GN version fails occasionally when run
concurrently with other invocations.
As Flutter does, this CL uses the clang toolchain to build for
Android. Thus, it is now possible to build for Android on MacOS.
This change is a prerequisite for assembling the SDK in GN
rather than with a python script:
https://codereview.chromium.org/2848943003/
and will be nicer for making prebuilt SDKs for Fuchsia.
Resubmitting this with the following fixes:
1. Rolls further forward to get past a GN bug
2. Fixes the Android build.
3. Style cleanups in gn.py

This reverts commit 6bf2c800fd.
There is still some strangeness with the new GN binary not wanting
to do an incremental build on top of a build that used an old GN
binary.

This reverts commit cc968ca45b.
This CL will have to be relanded in two pieces so that the
update to tools/gn.py lands before the unmodified version
can invoke the updated GN binary.

This change enables gn.py to take comma separated lists of modes,
architectures, and os's similar to build.py. It also accepts 'all'
for each of these just like build.py. GN is invoked in parallel to
save time.
This change also adds an option --gn to build.py to invoke ninja
instead of the usual build system.
Will investigate invoking tools/gn.py automagically from build.py in
a future change.
