Package Kit: Implement progress notifications.

- BJobStateListener: Add progress state and corresponding hook.
- FetchFileJob: Notify job progress hook on libcurl notifications.
- UserInteractionHandler: Add hooks for download progress and checksum
  validation progress.
- PackageManager: inherit from JobStateListener and watch for job
  notifications for internally generated jobs. Forward to corresponding
  UserInteractionHandler hooks as needed.
- Adapt pkgman, HaikuDepot and package_daemon to above changes.
  Neither HaikuDepot nor package_daemon's progress hooks are wired up to
  do anything yet though.
