	Rewritten to add content-type support.
	* src/DownloadHandler.{h, cc}
	* src/BtPostDownloadHandler.{h, cc}
	* test/BtPostDownloadHandlerTest.cc

	* src/RequestGroup.h
	* src/RequestGroupCriteria.h
	* src/ContentTypeRequestGroupCriteria.h

	Added 'mem' option value for --follow-metalink, 
--follow-torrent.
	If it is give, metalink/torrent file is not written to the disk, 
but
	just is kept in memory. Parsing is occurred on memory.
	* src/MetalinkHelper.{h, cc}
	* src/MetalinkProcessor.h
	* src/Xml2MetalinkProcessor.{h, cc}
	* test/Xml2MetalinkProcessorTest.cc

	* src/MemoryBufferPreDownloadHandler.{h, cc}
	* src/OptionHandlerImpl.h
	* src/prefs.h
	* src/Util.{h, cc}
	* test/UtilTest.cc
	
	Keep DownloadResult rather than RequestGroup after downloads to 
reduce
	memory usage.
	* src/RequestGroupMan.{h, cc}
	* src/DownloadEngine.cc
	* src/BtDependency.{h, cc}: Changed the type of dependee from
	WeakHandle to SharedHandle because WeakHandle could be null.

	* src/DownloadEngineFactory.cc
	* src/DownloadResult.h
	
	Set totalLength after download finished
	* src/UnknownLengthPieceStorage.{h, cc}

	Keep torrent file specified in metalink in memory.
	* src/Metalink2RequestGroup.cc
	* src/BtDependency.cc
	* src/TrueRequestGroupCriteria.h

	Fixed the bug: seekg is used where seekp should be used.
