cvsync 0.20.1

Changes:
	* Support libgcrypt and mhash libraries.

          If you want to use other hash library instead of native one,
          please specify HASH_TYPE.

          The following types are available:

                libgcrypt
                mhash
                native (default)
                openssl

          By this change, never fall back to OpenSSL automatically even if a
          native hash library is not available.

	* Option (cvscan)

                -c: Specifies the configuration file for cvsyncd.
                    cvscan use the information of scanfile (loose, nofollow,
                    release, prefix and so on) from it.
