`adb` can sometimes hang, which will in turn hang the Dart isolate if
we're using `Process.runSync()`. This changes many of the `Device` methods
to return `Future<T>` in order to allow them to use the async process
methods. A future change will add timeouts to the associated calls so
that we can properly alert the user to the hung `adb` process.
This is work towards #7102, #9567
There is a race where we could complete a future based on a stream event
and then before we cancel the stream subscription, we get another event
and try and complete the future again.
- [x] Switch the reassemble timeout to 5 seconds.
- [x] Print a status message if reassemble fails:

The first hot reload does a bunch of work that we used to hide behind the
loader screen. This PR changes the messsage printed to the user on the first
reload from:
'Performing hot reload...'
to:
'Initializing hot reload...'
Subsequent reloads say 'Performing hot reload...'
When invoked from the command line, relative paths aren't typically
used, but they are when invoked from within IDEA and prevents
IDEA from reading the files.
Also, remove flutterPackagesDirectory since it's not used
Generates an android.iml file and a package-level library for flutter.jar.
Does not set up an Android SDK in IDEA; this isn't possible with a
template-based approach. But IDEA shows a clear warning, so the
user can fix this by setting the SDK.
(When creating a Flutter project from within IDEA, we can fix this up
afterwards in the plugin.)
* Fix tests to use Ahem, and helpful changes around that
- Fix fonts that had metric-specific behaviours.
- LiveTestWidgetsFlutterBinding.allowAllFrames has been renamed
to LiveTestWidgetsFlutterBinding.framePolicy.
- LiveTestWidgetsFlutterBinding now defaults to using a frame policy
that pumps slightly more frames, to animate the pointer crosshairs.
- Added "flutter run --use-test-fonts" to enable Ahem on devices.
- Changed how idle() works to be more effective in live mode.
- Display the test name in live mode (unless ahem fonts are enabled).
- Added a toString to TextSelectionPoint.
- Style nit fixes.
* Roll engine to get Ahem changes.
* Update tests for dartdoc changes.
* Fix flutter_tools tests
Rename State.config to State.widget
Rename State.didUpdateConfig to State.didUpdateWidget
Renamed all State subclasses' local variables named config to something else
