Adds logic to ExternalStorageProvider to scan non-visible volumes, such as USB OTG devices. We use internal paths when surfacing these volumes, which also optimizes around the FUSE daemon for public devices. Also dumps internal state when requested. VolumeInfo now directly contains DiskInfo, which means it's snapshotted when sending events, avoiding teardown races. Switch notifications to use this DiskInfo directly. Finish wiring up new volume state, including helper methods to make it readable/writable state clearer. Handle disks and volumes with spaces in their labels.
