IpAddress and IpPrefix related cleanup:
 * Removed IpAddress.MAX_INET_MASK and use IpPrefix.MAX_INET_MASK_LENGTH
   instead
 * Renamed IpAddress.INET_LEN to INET_BYTE_LENGTH
 * Added IpAddress.INET_BIT_LENGTH, INET6_BYTE_LENGTH, and INET6_BIT_LENGTH
 * Removed methods that are semantically incorrect, or are not needed/used
   - IpAddress.prefixLength()
   - IpAddress.toPrefix()
   - IpAddress.mask()
   - IpAddress.netmask()
   - IpAddress.network()
   - IpAddress.host()
   - IpAddress.isMasked()
   - IpAddress.contains()
   - IpPrefix constructor for version and bytes (but no netmask)
   - IpPrefix.valueOf(int)
