illumos gate

libipmi.h contains a set of #defines for the various sensor-specific reading types as documented in Section 42.2 of the IPMI specification. A number of new reading types were added with rev 1.1 of the IPMI 2.0 spec and some of these new sensor reading types are used on Joyent platforms. To facility developing code to interact with these new types of sensors, we need to extend libipmi.h to include the necessary #defines.

Additionally, the set of LAN parameters that can be manipulated via the GET_LAN_CONFIG and SET_LAN_CONFIG commands has been extended in rev1.1 to include a number of new IPv6-specific parameters. We'll want to update the library accordingly. This will be leveraged by the changes for illumos#9458
