Doesn't quite work yet, but close. Fuchsia is on a newer Dart and will need a
couple patches before this will fully work.

* Create an Xcode project template for dynamic service creation.

The `create_native_service_sdk.py` will be run on the buildbot similar
to `create_ios_sdk.py`. This will create an Xcode project with both arm
and x64 assets that the user can use to fill in the service
implementation.

* Add the complete_static_lib property to sdk_lib_archive in
dynamic/BUILD.gn

It is called each time the embedder initializes a Flutter view controller. The Mac shell (which does not have a view controller), calls it before NSApplicationMain.

Common items like the base::AtExitManager and the platform message loop are stored in `EmbedderState`

We now use flutter.mojo instead.

Fixes Mac builds

Android and Linux builds.

Also fixes a couple of toolchain selection issues.

Instead of using a collection of Python scripts to generate the artifacts we
want to distribute from this repository, we should just use the build system.
This CL adds a top-level |dist| target that creates these artifacts in a "dist"
directory of the build output.

Sky itself does't need to depend on //services/debugger. That's already taken
care of by //services depending on //services/debugger. Also, add some direct
depenencies from //sky/sdk to the mojom interfaces used by //sky/sdk.

Moving sky_viewer into services/sky is more consistent with how all the other
content handlers (e.g., dart, js, nacl, pdf, python) are organized.

This CL builds an APK for MineDigger that works offline. We use |sky_packager|
to snapshot the Dart code, which we then extract from the APK during startup.
If we succeed in extracting a snapshot, we load it by default.

This CL makes it possible to build sky_shell on Linux. It doesn't do much, but
it doesn't crash on startup. The goal is to evetually be able to test sky_shell
on the bots and to be able to run the test_sky on Mac.

sky_packager is a tool that generates a Dart script snapshot for Dart files
intended to run with dart:sky. I plan to use this tool to experiment with
startup performance.

This makes the icons look nicer on the Nexus 5

I briefly played with trying to figure out which drawable_*
to use dynamically, but I couldn't seem to write a reasonable
solution which worked on both Desktop and my Nexus 5, leading
me to believe I didn't understand how it should work and just
went with xxhdpi for now.

Sky debugger is a native mojo app that puts up an http server and talks
to other mojo apps in response to http requests, allowing to
interactively start/stop tracing, profile, etc.

This is generally useful also when one does not run mojo_shell through
skydb, hence this patch pulls the debugger into services/debugger.

We can then add plumbing for running with the debugger in devtools.

NOTE: This CL appears far larger than it actually is for two reasons:

1) Many files were moved around to use the Dart package directory structure.
2) Many .dart files had to have import paths updated.

- Organize mojo/public/dart so that it uses standard Dart package layout
- Organize mojo/dart/apptest so that it uses a standard Dart package layout
- Organize sky/sdk so that it uses a standard Dart package layout
- Create a mojo/testing package (used by unittests)
- Introduce the 'dart_pkg' gn rule which populates gen/Config/dart-pkg
- All internally vended Dart packages must have a corresponding dart_pkg rule
- It is now possible to use dependency_overrides: in pubspec.yaml to mix internal and external package dependencies (enables analyzer, editor, webstorm usage for internal developers).
- Package root for dart content handler ends with "packages/"
- Imports of mojo package uris no longer need the "public/dart"
- mojo/public/tools/dart_package.py is a clone of mojo/public/tools/gn/zip.py
- Sky tests no longer run 'deploy_sdk' script.

defaults to the stocks demo app. Sky Shell is now a library that can be
packaged by different APKs.

This CL adds a SkyShell.apk, which will become a direct embedding of Sky on
Android that will let us run performance tests on the Sky engine in a
self-contained environment on a real device.

Sky can't really build on its own.  We were previously
using the 'sky' build target for this but it didn't
fully anticipate all of our dependencies.  The most
recent break was when James removed /mojo/shell
from mojo.

Instead of sky listing out each and every service
which it depends on, we should just get used to
building root like other mojo developers.

Thankfully there is already a helpful tool
for this called mojob.py.  I've updated our
readme to reflect this, and removed the mojo
dependency on the sky build group.

The purpose of the sky build group is to expose
all of the sky build targets up to the root level
BUILD.gn (which only depends on /sky), not to
be an independently buildable target.
