8ca0b4127d Fix X25519 on OS X when using build systems other than CMake.
Assembly code for X25519 wasn't included on OS X when built with
build systems other than CMake, which lead to a SIGTRAP due to a
missing x25519_x86_64.

686bb19ba1 Add a unit test for one-sided shutdown.
OpenSSL was actually super-buggy here (though known bugs on our end have been
fixed), but pyOpenSSL was confused and incorrectly documented that callers call
SSL_read after SSL_shutdown to do bidi shutdown, so we should probably support
this. Add a test that it works.

db207264ad newhope: refactor and add test vectors.
The test vectors are taken from the reference implementation, modified
to output the results of its random-number generator, and the results of
key generation prior to SHA3.  This allows the interoperability of the
two implementations to be tested somewhat.

To accomplish the testing, this commit creates a new, lower-level API
that leaves the generation of random numbers and all wire encoding and
decoding up to the caller.

2f87112b96 Never expose ssl->bbio in the public API.
OpenSSL's bbio logic is kind of crazy. It would be good to eventually do the
buffering in a better way (notably, bbio is fragile, if not outright broken,
for DTLS). In the meantime, this fixes a number of bugs where the existence of
bbio was leaked in the public API and broke things.

- SSL_get_wbio returned the bbio during the handshake. It must always return
  the BIO the consumer configured. In doing so, internal accesses of
  SSL_get_wbio should be switched to ssl->wbio since those want to see bbio.
  For consistency, do the same with rbio.

- The logic in SSL_set_rfd, etc. (which I doubt is quite right since
  SSL_set_bio's lifetime is unclear) would get confused once wbio got wrapped.
  Those want to compare to SSL_get_wbio.

- If SSL_set_bio was called mid-handshake, bbio would get disconnected and lose
  state. It forgets to reattach the bbio afterwards. Unfortunately, Conscrypt
  does this a lot. It just never ended up calling it at a point where the bbio
  would cause problems.

- Make more explicit the invariant that any bbio's which exist are always
  attached. Simplify a few things as part of that.

1d64afda44 Stop reseting init_num everywhere in the handshake loop.
This was needed because ssl3_get_message would get confused if init_num were
not set back to zero when reading the next message. However, ssl3_get_message
now treats init_num only as an output, not an input. (The message sending logic
and the individual handshake states still use it, so we can't get rid of it
altogether yet.)

I've kept the init_num reset at the start and end of the handshake loop alone
for now since that's more about initialization and cleanup. Though I believe
they too do not do anything.

1e6d6df943 Remove state parameters to ssl3_get_message.
They're completely unused now. The handshake message reassembly logic should
not depend on the state machine. This should partially free it up (ugly as it
is) to be shared with a future TLS 1.3 implementation while, in parallel, it
and the layers below, get reworked. This also cuts down on the number of states
significantly.

Partially because I expect we'd want to get ssl_hash_message_t out of there
too. Having it in common code is fine, but it needs to be in the (supposed to
be) protocol-agnostic handshake state machine, not the protocol-specific
handshake message layer.

a6338be3fa Simplify ssl3_get_message.
Rather than this confusing coordination with the handshake state machine and
init_num changing meaning partway through, use the length field already in
BUF_MEM. Like the new record layer parsing, is no need to keep track of whether
we are reading the header or the body. Simply keep extending the handshake
message until it's far enough along.

ssl3_get_message still needs tons of work, but this allows us to disentangle it
from the handshake state.

BUF_MEM is actually a rather silly API for the SSL stack. There's separate

We possibly don't want to be using it long-term anyway (if nothing else, the
char*/uint8_t* thing is irritating), but in the meantime, it'll be easier to
separately fix up get_message's book-keeping and state tracking from where the
handshake gets its messages from.

we send close_notify in parallel with the peer and sendAlert(alertCloseNotify)

For convenience, sendAlert returns a local error for non-close_notify alerts.
Suppress that error to avoid the race condition. This makes it behave like the
other shimShutsDown tests.

f4ce8e5324 Refactor ECDH key exchange to make it asymmetrical
Previously, SSL_ECDH_METHOD consisted of two methods: one to produce a
public key to be sent to the peer, and another to produce the shared key
upon receipt of the peer's message.

This API does not work for NEWHOPE, because the client-to-server message
cannot be produced until the server's message has been received by the
client.

Solve this by introducing a new method which consumes data from the
server key exchange message and produces data for the client key
exchange message.

68a533c0ef Fix line-number counting in doc.go.
There's an off-by-one when skipping blank lines. The initial logic also has an
off-by-one but since it starts lineNo 0-based and then switches to 1-based, it
cancels out.

The decl error line number also was not of where the decl began.

c7eae5a326 Forbid calling SSL_read, SSL_peek, and SSL_do_handshake post-shutdown.
This explicitly forbids an API pattern which formerly kind of worked, but was
extremely buggy (see preceding commits). Depending on how one interprets
close_notify and our API, one might wish to call SSL_shutdown only once
(morally shutdown(SHUT_WR)) and then SSL_read until EOF.

However, this exposes additional confusing states where we might try to send an
alert post-SHUT_WR, etc. Early commits made us more robust here (whether one is
allowed to touch the SSL* after an operattion failed because it read an alert
is... unclear), so we could support it if we wanted to, but this doesn't seem
worth the additional statespace. See if we can get away with not allowing it.

ea65e100c7 Condition the read_close_notify check on type, not shutdown state.
The logic to drop records really should be in the caller. Unless
ssl3_read_bytes is broken apart, condition on the type field which is more
robust.

If we manage to call, say, SSL_read after SSL_shutdown completes at 0 (instead
of 1), this logic can incorrectly cause unknown record types to be dropped.

fa214e4a18 Tidy up shutdown state.
The existing logic gets confused in a number of cases around close_notify vs.
fatal alert. SSL_shutdown, while still pushing to the error queue, will fail to
notice alerts. We also get confused if we try to send a fatal alert when we've
already sent something else.
