* Revert "Include _http into sky_engine libraries for analyzer (#4154)"
This reverts commit b930f107c3d6648423c42ed10b54f36a92edcbc8.
It is dependent upon the Dart roll, which breaks the engine.
* Revert "Roll dart to ade37f931e90b0fdb8fe16d6bf6f089545da55b6 (#4151)"
This reverts commit 6f1264fb3e11d25a26bc7c44246110ecb5159011.
This Dart roll breaks the engine build on Travis.
* Introduce frontend_server that allows for interactive and batch modes.
Example of batch mode:
```
$ dart $HOME/p/f/t11/flutter/engine/src/flutter/frontend_server/bin/server.dart --sdk-root=$HOME/p/f/t11/flutter/engine/src/out/android_debug/flutter_patched_sdk --platform-kernel-dill=$HOME/p/f/t11/flutter/engine/src/out/android_debug/flutter_patched_sdk/platform.dill $HOME/p/f/t11/flutter/flutter/examples/flutter_gallery/lib/main.dart
out: result 79256789-598c-4909-a9e4-0ef36d4c26ba
out: 'State&TickerProviderStateMixin^#U0^' is exported from both 'package:flutter/src/widgets/animated_cross_fade.dart' and 'package:flutter/src/widgets/animated_list.dart'.
...
out: Superclass has no method named 'hitTest'.
out: 79256789-598c-4909-a9e4-0ef36d4c26ba $HOME/p/f/t11/flutter/flutter/examples/flutter_gallery/lib/main.dart.dill
$
```
Example of interactive mode - communication via stdin/stdout:
```
$ dart $HOME/p/f/t11/flutter/engine/src/flutter/frontend_server/bin/server.dart --sdk-root=$HOME/p/f/t11/flutter/engine/src/out/android_debug/flutter_patched_sdk --platform-kernel-dill=$HOME/p/f/t11/flutter/engine/src/out/android_debug/flutter_patched_sdk/platform.dill --incremental
out: Frontend server is ready.

This allows analysis to succeed. Otherwise we're seeing errors on List which does not appear as Iterable in core/list.dart unless one has knownledge of EfficientLengthIterable which is defined in internal/internal.dart.
The platform use cases are handled by the PlatformPlugin. The media service and
the sensor service have no clients. If we want to use them, we should create
plugins for them.
