* cleanup remaining commands to use throwToolExit for non-zero exit code
* remove isUnusual exception message
* add type annotations for updated args package
* convert pubGet to throw ToolExit on non-zero exit code
* convert commandValidator to throw ToolExit for non-zero exit code
* convert flutter commands to throw ToolExit for non-zero exit code

When using --use-application-binary:
- [x] Stop flutter run from checking for a pubspec.yaml in current directory
- [x] Stop flutter run from invoking pub get
- [x] Set 'shouldBuild' based on --use-application-binary
- [x] Stop requiring 'lib/main.dart' to be present before running.
- [x] Stop building an FLX when launching on Android
* refactor _run to runCmd
* replace requiresProjectRoot getter with call to commandValidator
* replace requiresDevice getter with call to findTargetDevice
* trace command requires a debug connection, not a device
* inline androidOnly getter
* rename command methods to verifyTheRunCmd and runCmd
* move common verification into BuildSubCommand
* rename deviceForCommand to device
* rename methods to verifyThenRunCommand and runCommand
* General improvoments to the loader app:
* Show a message after 8 seconds if no connection comes in.
* Show a progress bar as files are being uploaded.
* Hide the spinner just before launching the application.
* General improvements to the "flutter run" UI:
* Add "?" key as a silent alias for "h".
* Make the help text bold so it doesn't get mixed with the logs.
* Make "R" do a cold restart when hot reload is enabled.
* Supporting features and bug fixes:
* Add support for string service extensions.
* Other bug fixes:
* Expose debugDumpRenderTree() outside debug mode.
* Logger.supportsColor was missing a getter.
* Mention in the usage docs that --hot requires --resident.
* Trivial style fixes.
This prevents multiple simultaneous runs of the analyzer from stomping
over each other (e.g. multiple runs of 'update-packages'). Certain
long-lived commands (like analyze, run, logs) are exempted once they've
done enough work to be safe from most stomping action.
This still doesn't make us entirely safe from craziness, e.g. if you're
half way through an 'update-packages' run and you call 'git pull', who
knows what state you'll end up in. But there's only so much one can do.
