Subject: Support database rebuild disabling when USB is connected for all e200
 OF versions. Some people may have to update the OF (to any version they want)
 using sansapatcher before it will work. This just ensures that the NVPARAMS
 are in a good state and we can be sure where to look for the rebuild flag.The
 c200 OF doesn't reboot before rebuilding the database, so our trick won't
 ever work there.
