Introduce '[ipaddr]:path' notation.

Since the existing implementation searches ':' backward, a path which
includes ':' could not be mounted.  You can now mount such path by
enclosing an IP address by '[]'.
Though we should change to search ':' forward, it will break
'ipv6addr:path' which is currently working.  So, it still searches ':'
backward, at least for now.
