[sr-dev] executing tm:branch-failure event_route also when t_relay() fails?

[Juha Heinanen]

i did some reading of tm code and found that currently tm:branch_failure
block seems to be handled only by code in t_reply.c.  when t_relay() fails
there is no reply processing and thus no execution of tm:branch-failure
block.

perhaps something similar to t_reply()/run_branch_failure_handlers()
could be done in t_send_branch() when sending fails?  i'm pretty sure
that t->on_branch_failure is set in t_send_branch().  it is thus the
matter on getting the corresponding tm:branch_failure block executed.
