    Guard against retransmitting BYEs indefinitely
    
    In the case of an attended transfer (A calls B, A atxfers to C) where
    A becomes unreachable before replying to Asterisk's BYE, Asterisk can
    sometimes retransmit the BYE indefinitely. This is because
    __sip_autodestruct tests p->refer && !ast_test_flag(&p->flags[0],
    SIP_ALREADYGONE and will then transmit a BYE. When this BYE times out,
    it will not ever be marked as ALREADYGONE, so when __sip_autodestruct
    is called again, we end up starting the cycle over.
    
    This patch adds a call to sip_alreadygone(pkt->owner) in retrans_pkt
    in the case of a BYE that has timed out. This should prevent Asterisk
    from trying to transmit new BYE messages in the future.
