Refactors KernelCompiler and ResidentCompiler to no longer use globals (except as a fallback for g3 migration). Improves the compilation error when running flutter test on a package without a flutter_test dependency.
Updates machine mode to output trace text to stderr
Make it possible for all FlutterCommands to be global free, by moving instantiation to inside the Zone context. Additionally, provide VerboseLogger and NotifyLogger (daemon) at the top level and remove from command-specific overrides.
This allows removing a work around where web devices needed to look up directly from the context in non-test code.
Technically the output preferences are still zone injected, but these will be moved soon as they were not being used correctly by the top level command (the injection comes after ArgParser reads the overflow values, causing numerous wrap issues)
* Prposal for supporting URL tunnelling
* Update daemon.md
* Add the ability for daemon to call clients to expose URLs
* Fix dwds mock in web_fs tests
* Fix type error
* Remove build_runner import from run
* Move appStartedTime back to after the app has started
* Remove nested DI scope and pass urlTunneller down
* Fix import
* Tweak TODO
* Fix existing tests
* Fix spec to use result instead of params for response object
* Fix exposeUrl to use a url field, as spec'd
* Test that the daemon's exposeUrl sends a request and handles the response
* Update project.pbxproj files to say Flutter rather than Chromium
Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
* Update the copyright notice checker to require a standard notice on all files
* Update copyrights on Dart files. (This was a mechanical commit.)
* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).
* Clean up the copyrights in non-Dart files. (Manual edits.)
Also, make sure templates don't have copyrights.
* Fix some more ORGANIZATIONNAMEs
* de-null dartDefines in daemon mode
* remove daemonCommand; pipe through dartDefines into Daemon
* pass dartDefiles in attach; add test for --machine mode
