Sorry, I meant converting die() into:

  rp_error(...);
  die(...);

possibly via an rp_die() helper.  The existing rp_error() cases would
remain untouched.

Installing a die handler could make that work automatically, though I
suspect it would lead to corner cases where we break protocol (e.g., if
we die() in the middle of writing out a packet).
