Subject: added support for downloading debdelta files and queuing successfully
 downloaded debdeltas for processing with the debdelta apt method, in
 apt-pkg/acquire-item.{cc,h} in pkgAcqArchive class. Currently, no index for
 deltas are used. Proper progress reporting and methods to verify the
 debdeltas are yet to be added.
