With and ok deraadt@, something similar has been in the snaps for a while.

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@

Only check errno if read() has returned an error. EOF is
not an error. This fixes a problem where the mux master would sporadically
fail to notice that the client had exited. ok mikeb@ djm@

Avoid ugly "DISPLAY "(null)" invalid; disabling X11

Revert "account for packets buffered but not yet
