	Create MessageDigestHelper::staticSHA1DigestInit() which uses
	statically declared sha1 MessageDigestContext.
	* src/BtPieceMessage.cc: Use staticSHA1DigestInit() to avoid
	initialization of short-lived MessageDigestContext.
	* src/MessageDigestHelper.{h, cc}
	* src/main.cc
	
	Now DownloadCommand has a reference to MessageDigestContext to avoid
	the initialization of MessageDigestContext every time in validating
	chunk checksum.
	* src/DownloadCommand.{h, cc}
