	* See [quagga-dev 1815]
	* kernel_socket.c: (rtm_write) Use SAROUNDUP when HAVE_SIN_LEN
	  is not available.
	* rt_socket.c: (kernel_rtm_ipv6(_multipath)) set family to
	  AF_INET6 on ipv6 routes.

	* kernel_socket.c: Add RTA_NAME_GET macro to extract name from
	  sockaddr_dl. Add some more RTF_ flags.
	* (ifan_read) Add some debug messages.
	* (ifm_read) Add more debug messages. More robust cross-checks
	  of index against name.
	  Fall back to by-name lookup if the index lookup fails, future
	  proofing more than anything else.
	  (ifam_read_mesg) Read RTA_IFP. Add debug messages.
	  (ifam_read) More debug. If there's an RTA_IFP and it isn't
	  the name of the interface, save it as the label.
	  (rtm_read_mesg) Read RTA_IFP.
	  (rtm_read) allow name to be retrieved.
	  (rtmsg_debug) expand on the debug message.
