illumos gate

To test the case where we had a bad table, I went back and used mdb to lie about the table structure size and said it was 5 bytes. this resulted in an error:

...
> 8069d0b/v 5
0x8069d0b:      0x16    =       0x5> :c
failed to read power supply information: Structure table is shorter than expected

mdb: stop at smbios_info_powersup
mdb: target stopped at:

To test the normal path I decoded the PSU information in four different five different smbios binary images from different generations of systems. Example output:
