* Leave only widget creation tracker kernel pass in flutter frontend server.
This is follow-up to https://dart-review.googlesource.com/c/sdk/+/43888.
* Adapt to updated interface
* Tyop
* Fix imports. Compiler interface extension
* Add trivial test back. Rename library to flutter_frontend_server.
* Add option for recompile request to switch to new main file(entrypoint).
This is needed to reuse incremental compiler to compile unrelated programs. First use case is reuse single
incremental compiler for all tests run by 'flutter test'
* Remove left over print
* Support .packages option in frontend_server, bundle_path in main_mac.
This is needed to be able to run in mode.
* Remove byte store tests
* Remove unused import
* Fix formatting
* Enable flutter test argument passing on win and linux.
* Fix formatting
* Roll Dart to 93d8c9fe2a2c22dc95ec85866af108cfab71ad06.
* Fix analyzer nits
* Try to pin dependency for tools/licenses to convert 2.0.1. Add verbose flag to pub get
* Pin dart to dev.16 to overcome pub issue
* Revert "Try to pin dependency for tools/licenses to convert 2.0.1. Add verbose flag to pub get"
This reverts commit d525a83f4494a511996226d328a5208d4651d46e as it is no
longer needed, was added to diagnose the problem, which turned out to be
a problem with pub in latest dart dev release.
* Fix license hash
* Reintroduce api methods and tests
* Add a --strong option to the front end server so we can use strong mode with preview-dart-2.
* Plumb the --strong option through the dart controller into the VM.
* - Build a strong version of platform.dill for use with the engine.
- Fix a strong mode static error in the assert statement
* Enable asserts when running debug version even in strong mode.
* Use the correct platform dill file for linking when doing the aot builds.
* Fix formatting issue.
* Roll dart to pick up fix for diagnostic server
* Fix runUnaryGuarded, runBinaryGuarded calls
* Revert changes to runUnaryGuarded, runBinaryGuarded as they seem to be local-only, perhaps dependent on version of analyzer
* Update third_party license hash. No changes to licenses
* Fix problem with _filename not being set. Add tests for that(and add mockito to mock IKG).
* Initialize KernelSerializer, Fix indentation
* Style nits and reworded comment
* 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'.

$
```
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.
