freeipmi lacks IPv6 support

[LaMont Jones]

ipmipower in 1.4.11 and 1.5 lack ipv6 support. This is in-plan for 1.6 from upstream.

See also related bug 1645912.

The -h argument to ipmipower needs to be extended to accept [ip:v6::addr]:port type syntax, and the processing of the hostnames needs to take into account ipv6 addresses as well.

[Impact]

 * If a BMC has only IPv6 addresses, then ipmipower cannot discover it.

 * MAAS needs to be able to do just that.

[Test Case]

 * To reproduce / verify the bug, configure a BMC with an IPv6 address, and
   try to talk to it.

[Regression Potential]

 * If a BMC has both IPv6 and IPv4 addresses in the DNS, and the hostname
   is used to control it, then this change will cause ipmipower to try
   IPv6 first, where it used to completely ignore IPv6 in the DNS. We
   believe this to be the correct behavior and that it does not affect
   the current installed base. (IPv6 BMC addresses are not a thing that
   we have been able to find anywhere.)

Valid bug, but needs to be pushed upstream.

FreeIPMI maintainer here. Google alerts pointed me to this ticket. IPv6 has been on my todo list forever, but lacked motivation to do it b/c need appeared to be low. Could original reporter create a ticket in Savannah (http://savannah.gnu.org/projects/freeipmi) and Github (https://github.com/chu11/freeipmi-mirror). Thanks.

As an aside, support of IPv6 in the IPMI specification was released very recently (2014 according to Wikipedia). So unclear what original reporter means by OpenIPMI IPv6 support since 2003. Perhaps it was a OEM specific extension added by a vendor? Unclear to me if OpenIPMI has supported "standard" IPv6 in newer versions.

See also https://github.com/chu11/freeipmi-mirror/pull/7 -- IPv6 support is in-plan for freeipmi 1.6, and we'll be pulling various bits back into 1.4/1.5 for Ubuntu, starting with ipmipower getting support for IPv6.
