Manuel Pégourié-Gonnard ce8588c9ef Make udp_proxy more robust
There seemed to be some race conditions with server closing its fd right after
sending HelloVerifyRequest causing the proxy to exit after a failed read.

Manuel Pégourié-Gonnard db2858ce96 Preparation for timers
Currently directly using timing.c, plan to use callbacks later to loosen
coupling, but first just get things working.

Manuel Pégourié-Gonnard bd97fdb3a4 Make ssl_server2's HVR handling more realistic
It makes not sense to keep the connection open until the client is verified.
Until now it was useful since closing it crates a race where the second
ClientHello might be lost. But now that our client is able to resend, that's
not an issue any more.

Manuel Pégourié-Gonnard fa60f128d6 Quit using "yes" in ssl-opt.sh with openssl
It caused s_server to send an AppData record of 16Kb every millisecond or so,
which destroyed readability of the proxy and client logs.

Manuel Pégourié-Gonnard cd32a50d67 Fix NewSesssionTicket vs ChangeCipherSpec bug
Since we were cheating on state, ssl_read_record() wasn't able to drop
out-of-sequence ChangeCipherSpec messages. Cheat a bit less.
