Main changes: * Change the listing order of files/directories so that the local and remote snapshots can be compared on-the-fly. * Introduce a new struct called EntryList that maintains a list of files/directories, which are kept in memory when the number is lower, and serialized into a file when there are too many. * EntryList can also be turned into an on-disk incomplete snapshot quickly, to support fast-resume on next run. * ChunkOperator can now download and upload chunks, thus replacing original ChunkDownloader and ChunkUploader. The new ChunkDownloader is only used to prefetch chunks during the restore operation.
