Would it be possible to move out struct status from xrow.h and
rename to box_status and move to box.h or some other place?
Perhaps we should remove it altogether, and simply pass multiple
members to xrow_decode_status()?

Other request member combos, such as authentication or call or eval have
not leaked into xrow.h before. 

Otherwise the patch is OK to push.
