    upstream commit

    refactor activation of rekeying

    This makes automatic rekeying internal to the packet code
(previously
    the server and client loops needed to assist). In doing to it makes
    application of rekey limits more accurate by accounting for packets
    about to be sent as well as packets queued during rekeying events
    themselves.

    Based on a patch from dtucker@ which was in turn based on a patch
    Aleksander Adamowski in bz#2521; ok markus@
