Call callback with an extra boolean indicating whether the sample read was

       * collector.c (on_read): Call callback with an extra boolean
       indicating whether the sample read was the first one

       * collector.c (add_trace_to_stash): Allocate addresses on the
       stack if possible.

       * sysprof.c (on_new_sample): Only call update_sensitivity() on the
       first sample.

       * stackstash.c (stack_stash_add_trace): Move match to front
