	MessageDigestHelper is introduced in order to simplify the use
	of message digest. Removed repeated code.
	The message digest algorithm is now specified by string, like 
"sha1",
	"md5".

	* src/MessageDigestHelper.{h, cc}: New class.
	* src/DefaultPieceStorage.cc
	* src/DefaultBtContext.{h, cc}
	(computeFastSet): New function.
	(setInfoHash): Added for unit testing.
	(setNumPieces): Added for unit testing.

	* src/Peer.cc
	* src/Checksum.h
	* src/message.h
	* src/IteratableChecksumValidator.h
	* src/ChunkChecksumValidator.{h, cc}: Use 
IteratableChecksumValidator
	inside it.

	(checkIntegrity): Removed.
	* src/IteratableChunkChecksumValidator.{h, cc}
	* src/Util.h
	(sha1Sum): Removed.
	(simpleMessageDigest): Removed.
	(fileChecksum): Removed.

	Fixed comilation error when message digest is disabled.
	* src/MetalinkEntry.{h, cc}
	* src/MetalinkRequestInfo.cc
	
	Removed srandom and random.
