|BN_mod_inverse| is expensive and leaky. In this case, we can avoid
it completely by taking advantage of the fact that we already have
the two values that are supposed to be inverses of each other.

Also add a note about the applicability of the special case logic for

svaldez and I stared at this for a while and we believe this change is
correct. It's also irrelevant because our only remaining ADB (ANY

be omitted. Also, if it did, it would be a slight change in behavior.
We'd switch from using POLICYQUALINFO's default_tt (filling in an

The fallback version replaces the maximum version when it is set for
almost all purposes, except for downgrade protection purposes.

It seems risky in the context of cross-signed certificates when the

best. Thanks to Viktor Dukhovni for pointing this change out to me.

Our CBB patterns do not make it safe to use a CBB after any operation
failed. Suppose one does:
int add_to_cbb(CBB *cbb) {
CBB child;
return CBB_add_u8(cbb, 1) &&
CBB_add_u8_length_prefixed(cbb, &child) &&
CBB_add_u8(&child, 2) &&
/* Flush |cbb| before |child| goes out of scoped. */
CBB_flush(cbb);
}
If one of the earlier operations fails, any attempt to use |cbb| (except
CBB_cleanup) would hit a memory error. Doing this would be a bug anyway,
since the CBB would be in an undefined state anyway (wrote only half my
object), but the memory error is bad manners.
Officially document that using a CBB after failure is illegal and, to
avoid the memory error, set a poison bit on the cbb_buffer_st to prevent
all future operations. In theory we could make failure +
CBB_discard_child work, but this is not very useful and would require a
more complex CBB pattern.

This adds three more formats to the SSLKEYLOGFILE format to support TLS
1.3:
EARLY_TRAFFIC_SECRET <client_random> <early_traffic_secret>
HANDSHAKE_TRAFFIC_SECRET <client_random> <handshake_traffic_secret>
TRAFFIC_SECRET_0 <client_random> <traffic_secret_0>
(We don't implement 0-RTT yet, so only the second two are implemented.)
Motivations:
1. If emitted the non-traffic secrets (early, handshake, and master) or
the IKMs, Wireshark needs to maintain a handshake hash. I don't
believe they need to do this today.
2. We don't store more than one non-traffic secret at a time and don't
keep traffic secrets for longer than needed. That suggests three
separate lines logged at different times rather than one line.
3. If 0-RTT isn't used, we probably won't even compute the early traffic
secret, so that further suggests three different lines.
4. If the handshake didn't get far enough to complete, we won't have an
TRAFFIC_SECRET_0 to log at all. That seems like exactly when
Wireshark would be handy, which means we want to log secrets as they
are computed.
MT from NSS has ACK'd over email that this format would be acceptable
for them, so let's go with it.

Every flush but the last is always immediately followed by a read. Add a
combined wait mode to make things simpler. Unfortunately, both flights
we have (the state machine doesn't write the first ClientHello) are
followed immediately by a state change, which means we still need some
state in between because we must run code after write_message but before
read_message.
(This way to fix that is to get rid of the buffer BIO, change
write_message to write_flight, and allow things like init_message /
finish_message / init_message / finish_message / set_write_state /
init_message / finish_message / write_flight.)
