Implemented checksum validation feature(1 checksum for each
file)
The validation takes place after the download.
* src/PieceHashCheckIntegrityEntry.{h, cc}: New class.
* src/IteratableChecksumValidator.{h, cc}: Rewritten.
* src/CheckIntegrityCommand.cc: Changed log message.
* src/Metalink2RequestGroup.cc: Set checksum to
SingleFileDownloadContext.
* src/StreamCheckIntegrityEntry.{h, cc}: Now derived from
PieceHashCheckIntegrity class.
* src/BtCheckIntegrityEntry.{h, cc}: Now derived from
PieceHashCheckIntegrity class.
* src/ChecksumCheckIntegrityEntry.{h, cc}: New class.
* src/IteratableValidator.h: New class.
* src/message.h
* src/CheckIntegrityEntry.{h, cc}
* src/IteratableChunkChecksumValidator.{h, cc}
* src/SingleFileDownloadContext.h
* src/DownloadCommand.cc
--allow-overwrite=true is no longer needed to check file
integrity
before download in BitTorrent download.
* src/RequestGroup.cc (getInitialCommand)
Removed RequestGroup from queue when
RequestGroup::getInitialCommand()
throws exception.
* src/RequestGroupMan.cc (getInitialCommands)
