Put gone device timer into a structure tag that can hold more than 32 seconds. Oops.

Browse Source 
Untangle some of the confusion about what role means when it's in the FCPARAM/SDPARAM
or isp_fc/isp_spi structures. This fixed a problem about seeing targets appear if you've
turned off autologin and find them, or rather don't, via camcontrol rescan.
