DROPTION_FLAG_ACCUMULATE is not reset on detach

drcachesim has an accumulation option -record_function and you can see in the burst_malloc test, which does several re-attaches, that the option is never reset on detach:

droption today has no control point on exit or detach. Maybe it could provide a droption_reset_values() function and clients could call it in their exit events?
