The client and server both have to decide on behaviour when resuming a
session where the EMS state of the session doesn't match the EMS state
as exchanged in the handshake.
Original handshake
| No Yes
------+--------------------------------------------------------------
|
R | Server: ok [1] Server: abort [3]
e No | Client: ok [2] Client: abort [4]
s |
u |
m |
e |
Yes | Server: don't resume No problem
| Client: abort; server
| shouldn't have resumed
[1] Servers want to accept legacy clients. The draft[5] says that
resumptions SHOULD be rejected so that Triple-Handshake can't be done,
but we'll rather enforce that EMS was used when using tls-unique etc.
[2] The draft[5] says that even the initial handshake should be aborted
if the server doesn't support EMS, but we need to be able to talk to the
world.
[3] This is a very weird case where a client has regressed without
flushing the session cache. Hopefully we can be strict and reject these.
[4] This can happen when a server-farm shares a session cache but
frontends are not all updated at once. If Chrome is strict here then
hopefully we can prevent any servers from existing that will try to
resume an EMS session that they don't understand. OpenSSL appears to be
ok here: https://www.ietf.org/mail-archive/web/tls/current/msg16570.html

bn_test's output is meant to be piped to bc, but this got broken somewhat:
- OpenSSL uses uppercase hex rather than BoringSSL's lowercase. bc only accepts
uppercase. Document that this needs some shell pipeline until we replace
them with better tests because this is all ridiculous.
- Some stderr outputs moved to stdout to avoid cluttering stdout. Just remove
them. The operations are fast enough to not need progress.
- To cut down on noise, only write the bc transcript given a command-line flag.
Also remove the -results flag since it's pointless. (It writes only the
