Also fixes: roc-streaming#1, roc-streaming#16, roc-streaming#17, roc-streaming#66

- Initiate request for notification and microphone permissions
  and media projection on the dart side of AndroidBackend.

- Implement those requests in MainActivity.kt and rework
  AndroidConnector to redirect those requests to activity.

- Automatically stop media projection when both sender and receiver
  are stopped. Prevent service from stopping projection while we
  are starting sender and receiver.

- Implement synchronization and fix various races.

- Use foreground service instead of bound service, to keep it
  running when app closes.

- Forbid swiping away notification on lock screen.
  (We can forbid it only for lock screen).

- Stop sender and receiver when notification is swiped away.

- Add AndroidListener, to pass events from kotlin to dart.
  Implement in in AndroidBackend on dart side.

- Add AndroidSenderSettings, AndroidReceiverSettings, and pass them
  from model to kotlin.

- Hard-code ports in model instead of kotlin.

- Implement Backend.getLocalAddresses().

- Improve comments.

- Refactor android service code.

- Remove unused values from strings.xml.

- Merge all kotlin files into on package

- Merge kotlin and java directories

- SenderReceiverService => StreamingService

- android_connector => android_bridge
  (because it now defines AndroidConnector + AndroidListener)

- android_bridge.dart => android_bridge.decl.dart
  (this file is never imported directly)
