the code in t_reply.c for branch failure handling already looks very
similar to failure handling.  run_failure_handlers() use branch

	on_failure = t->uac[picked_branch].on_failure;

whereas run_branch_failure_handlers() use branch

	on_branch_failure = t->uac[picked_branch].on_branch_failure;

then both create faked request environment, run the route handler, and
restore the original environment.

why the faked request in case of branch failure does not include correct
$ru goes beyond my knowledge of tm module.
