    RX: Avoid retrying calls on busy channels
    
    When we receive an RX_PACKET_TYPE_BUSY packet, we currently ignore it.
    This is a problem when the server has a long-running call on that same
    call channel that we don't know about, since we will then keep
    retrying the call on the same channel and keep getting
    RX_PACKET_TYPE_BUSY responses.
    
    Try to avoid this by returning the RX_CALL_TIMEOUT error when we get a
    BUSY packet and there are other free call channels available on the
    conn. When the application gets the error and retries the call, we
    avoid using the same call channel again where possible. When all of
    the call channels appear busy, we revert to effectively the old
    behavior of retrying the call on the same channel until we get an
    RX_CALL_DEAD (or similar) error.
