Fixes https://github.com/flutter/flutter/issues/20303

This reflects that we no longer uses travis. Scripts are moved to ci folder.

Note that the license script won't work if there are untracked files

This reverts commit 503ba7c4.

Fixes https://github.com/flutter/flutter/issues/19776

* Update hash.

Adds --dynamic and --interpreter flags to
tools/gn. These flags result in engines with
properties as follows:

--dynamic:
- JIT targeting native code on Android and
  DBC on iOS

--interpreter
- Target DBC even if running on Android.

For example:

gn --android --dynamic --interpreter --runtime-mode release

Will generate an engine:
- Without Dart asserts
- Without Observatory
- With JIT compililation to DBC

into out/android_dynamic_release_dbc

Addresses flutter/flutter#18028 for the engine repo, and synchronizes the analysis_options.yaml files between the engine and the flutter/flutter repo.

* Roll dart to f981f097602ca434ce0a36b1f704723cad105fb6

02e47a97313 [VM] Fix for issue 32188 (cannot use `pub` with --preview-dart-2)

Auto-roller completed checks. Merging.

* Generate .packages for both flutter_kernel_transformers and frontend_server in the same way

* Generate more precise .packages

Dart SDK itself does not use pub which forced us to manually maintain dependecy
overrides in the frontend server's pubspec.yaml. This is rather fragile and
easily breaks when dependencies in one of the "internal" packages change, but
the package is not published yet.

This change switches us to the same model of dependcies management that Dart SDK
itself is using.

Down side of this is that we can no longer do pub run test in the
frontend_server and have to run tests manually.

* Roll Dart to 011676641a8b4b77bb372384c712709cbf037675.

Reverts b6be9377 and uses Dart_NewExternalTypedDataWithFinalizer.
