This is the first part to fixing the SSL stack to be 2038-clean.
Internal structures and functions are switched to use OPENSSL_timeval
which, unlike timeval and long, are suitable for timestamps on all
platforms.
It is generally accepted that the year is now sometime after 1970, so
use uint64_t for the timestamps to avoid worrying about serializing
negative numbers in SSL_SESSION.
A follow-up change will fix SSL_CTX_set_current_time_cb to use
OPENSSL_timeval. This will require some coordinating with WebRTC.
DTLSv1_get_timeout is left alone for compatibility and because it stores
time remaining rather than an absolute time.

The DTLS stack has two very different APIs for handling timeouts. In
non-blocking mode, timeouts are driven externally by the caller with
DTLSv1_get_timeout. In blocking mode, timeouts are driven by the BIO by
calling a BIO_ctrl with BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT.
The latter is never used by consumers, so remove support for it.
BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT implicitly depends on struct timeval
being used for timestamps, which we would like to remove. Without this,
the only public API which relies on this is the testing-only
SSL_CTX_set_current_time_cb which is BoringSSL-only and we can change at
our leisure.

The new APIs are SSL_CTX_set_strict_cipher_list() and
SSL_set_strict_cipher_list(). They have two motivations:
First, typos in cipher lists can go undetected for a long time, and
can have surprising consequences when silently ignored.
Second, there is a tendency to use superstition in the construction of
cipher lists, for example by "turning off" things that do not actually
exist. This leads to the corrosive belief that DEFAULT and ALL ought
not to be trusted. This belief is false.

Recent changes added SSL-level setters to these APIs. Unfortunately,
this has the side effect of breaking SSL_set_SSL_CTX, which is how SNI
is typically handled. SSL_set_SSL_CTX is kind of a weird function in
that it's very sensitive to which of the hodge-podge of config styles is
in use. I previously listed out all the config styles here, but it was
long and unhelpful. (I counted up to 7.)
Of the various SSL_set_SSL_CTX-visible config styles, the sanest seems
to be to move it to CERT. In this case, it's actually quite reasonable
since they're very certificate-related.
Later we may wish to think about whether we can cut down all 7 kinds of
config styles because this is kinda nuts. I'm wondering we should do
CERT => SSL_CONFIG, move everything there, and make that be the same
structure that is dropped post-handshake (supposing the caller has
disavowed SSL_clear and renego). Fruit for later thought. (Note though
that comes with a behavior change for all the existing config.)

In TLS 1.2, resumption's benefits are more-or-less subsumed by False
Start. TLS 1.2 resumption lifetime is bounded by how much traffic we are
willing to encrypt without fresh key material, so the lifetime is short.
Renewal uses the same key, so we do not allow it to increase lifetimes.
In TLS 1.3, resumption unlocks 0-RTT. We do not implement psk_ke, so
resumption incorporates fresh key material into both encrypted traffic
(except for early data) and renewed tickets. Thus we are both more
willing to and more interested in longer lifetimes for tickets. Renewal
is also not useless. Thus in TLS 1.3, lifetime is bound separately by
the lifetime of a given secret as a psk_dhe_ke authenticator and the
lifetime of the online signature which authenticated the initial
handshake.
This change maintains two lifetimes on an SSL_SESSION: timeout which is
the renewable lifetime of this ticket, and auth_timeout which is the
non-renewable cliff. It also separates the TLS 1.2 and TLS 1.3 timeouts.
The old session timeout defaults and configuration apply to TLS 1.3, and
we define new ones for TLS 1.3.
Finally, this makes us honor the NewSessionTicket timeout in TLS 1.3.
It's no longer a "hint" in 1.3 and there's probably value in avoiding
known-useless 0-RTT offers.

The TLS 1.2 state machine now looks actually much closer to the TLS 1.3
one on the write side. Although the write states still have a BIO-style
return, they don't actually send anything anymore. Only the BIO flush
state does. Reads are still integrated into the states themselves
though, so I haven't made it match TLS 1.3 yet.

On the TLS side, we introduce a running buffer of ciphertext. Queuing up
pending data consists of encrypting the record into the buffer. This
effectively reimplements what the buffer BIO was doing previously, but
this resizes to fit the whole flight.
As part of this, rename all the functions to add to the pending flight
to be more uniform. This CL proposes "add_foo" to add to the pending
flight and "flush_flight" to drain it.
We add an add_alert hook for alerts but, for now, only the SSL 3.0
warning alert (sent mid-handshake) uses this mechanism. Later work will
push this down to the rest of the write path so closure alerts use it
too, as in DTLS. The intended end state is that all the ssl_buffer.c and
wpend_ret logic will only be used for application data and eventually
optionally replaced by the in-place API, while all "incidental" data
will be handled internally.
For now, the two buffers are mutually exclusive. Moving closure alerts
to "incidentals" will change this, but flushing application data early
is tricky due to wpend_ret. (If we call ssl_write_buffer_flush,
do_ssl3_write doesn't realize it still has a wpend_ret to replay.) That
too is all left alone in this change.
To keep the diff down, write_message is retained for now and will be
removed from the state machines in a follow-up change.

Instead, "writing" a message merely adds it to the outgoing_messages
structure. The code to write the flight then loops over it all and now
shares code with retransmission. The verbs here are all a little odd,
but they'll be fixed in later commits.
In doing so, this fixes a slight miscalculation of the record-layer
overhead when retransmitting a flight that spans two epochs. (We'd use
the encrypted epoch's overhead for the unencrypted epoch.)

It's not completely clear to me why select_cetificate_cb behaves the way it
does, however not only is it confusing, but it makes assumptions about the
application using BoringSSL (it's not always possible to implement custom
logic outside of the callbacks provided by libssl), that make this callback
somewhat useless.
Case in point, the callback can be used for changing min/max protocol versions
based on per-site policies, and select_certificate_cb is the only place where
SSL_set_min/max_proto_version() can be used (e.g. you can't call them in
cert_cb because it's too late), but the decision on the specific versions to
use might depend on configuration that needs retrieving asynchronously from
over the network, which requires re-running the callback multiple times.

TLS 1.3 forbids warning alerts, and sending these is a bad idea. Per RFC
6066:
If the server understood the ClientHello extension but
does not recognize the server name, the server SHOULD take one of two
actions: either abort the handshake by sending a fatal-level
unrecognized_name(112) alert or continue the handshake. It is NOT
RECOMMENDED to send a warning-level unrecognized_name(112) alert,
because the client's behavior in response to warning-level alerts is
unpredictable.
The motivation is to cut down on the number of places where we send
non-closing alerts. We can't remove them yet (SSL 3.0 and TLS 1.3 draft
18 need to go), but eventually this can be a simplifying assumption.
Already this means DTLS never sends warning alerts, which is good
because DTLS can't retransmit them.

BN_FLG_CONSTTIME is a ridiculous API and easy to mess up
(CVE-2016-2178). Instead, code that needs a particular algorithm which
preserves secrecy of some arguemnt should call into that algorithm
directly.
This is never set outside the library and is finally unused within the
library! Credit for all this goes almost entirely to Brian Smith. I just
took care of the last bits.
Note there was one BN_FLG_CONSTTIME check that was still reachable, the
BN_mod_inverse in RSA key generation. However, it used the same code in
both cases for even moduli and φ(n) is even if n is not a power of two.
Traditionally, RSA keys are not powers of two, even though it would make
the modular reductions a lot easier.
When reviewing, check that I didn't remove a BN_FLG_CONSTTIME that led
to a BN_mod_exp(_mont) or BN_mod_inverse call (with the exception of the
RSA one mentioned above). They should all go to functions for the
algorithms themselves like BN_mod_exp_mont_consttime.
This CL shows the checks are a no-op for all our tests:

OpenSSL includes a leaf certificate in a certificate chain when it's a
client, but doesn't when it's a server. This is also reflected in the
serialisation of sessions.
This change makes the internal semantics consistent: the leaf is always
included in the chain in memory, and never duplicated when serialised.
To maintain the same API, SSL_get_peer_cert_chain will construct a copy
of the chain without the leaf if needed.
Since the serialised format of a client session has changed, an
|is_server| boolean is added to the ASN.1 that defaults to true. Thus
any old client sessions will be parsed as server sessions and (silently)
discarded by a client.

This change adds a STACK_OF(CRYPTO_BUFFER) to an SSL_SESSION which
contains the raw form of the received certificates. The X509-based
members still exist, but their |enc| buffer will alias the
CRYPTO_BUFFERs.
The serialisation format of SSL_SESSIONs is also changed, in a backwards
compatible way. Previously, some sessions would duplicate the leaf
certificate in the certificate chain. These sessions can still be read,
but will be written in a way incompatible with older versions of the
code. This should be fine because the situation where multiple versions
exchange serialised sessions is at the server, and the server doesn't
duplicate the leaf certifiate in the chain anyway.

Right now the only way to set an OCSP response is SSL_CTX_set_ocsp_response
however this assumes that all the SSLs generated from a SSL_CTX share the
same OCSP response, which is wrong.
This is similar to the OpenSSL "function" SSL_get_tlsext_status_ocsp_resp,
the main difference being that this doesn't take ownership of the OCSP buffer.
In order to avoid memory duplication in case SSL_CTX has its own response,
a CRYPTO_BUFFER is used for both SSL_CTX and SSL.

We currently look up SSL_HANDSHAKE off of ssl->s3->hs everywhere, but
this is a little dangerous. Unlike ssl->s3->tmp, ssl->s3->hs may not be
present. Right now we just know not to call some functions outside the
handshake.
Instead, code which expects to only be called during a handshake should
take an explicit SSL_HANDSHAKE * parameter and can assume it non-NULL.
This replaces the SSL * parameter. Instead, that is looked up from
hs->ssl.
Code which is called in both cases, reads from ssl->s3->hs. Ultimately,
we should get to the point that all direct access of ssl->s3->hs needs
to be NULL-checked.
As a start, manage the lifetime of the ssl->s3->hs in SSL_do_handshake.
This allows the top-level handshake_func hooks to be passed in the
SSL_HANDSHAKE *. Later work will route it through the stack. False Start
is a little wonky, but I think this is cleaner overall.

Due to recent changes, changing the SSL session timeout from cert_cb is
not possible anymore since the new |SSL_SESSION| is initialized *after*
cert_cb is run. The alternative would be using |SSL_CTX_set_timeout| but
the specific |SSL_CTX| could be shared by multiple |SSL|s.
Setting a value on a per-connection basis is useful in case timeouts
need to be calculated dynamically based on specific certificate/domain
information that would be retrieved from inside cert_cb (or other
callbacks).
It would also be possible to set the value to 0 to prevent session
resumption, which is not otherwise doable in the handshake callbacks.

This simplifies a little code around EMS and PSK KE modes, but requires
tweaking the SNI code.
The extensions that are more tightly integrated with the handshake are
still processed inline for now. It does, however, require an extra state
in 1.2 so the asynchronous session callback does not cause extensions to
be processed twice. Tweak a test enforce this.
This and a follow-up to move cert_cb before resumption are done in
preparation for resolving the cipher suite before resumption and only
resuming on match.
Note this has caller-visible effects:
- The legacy SNI callback happens before resumption.
- The ALPN callback happens before resumption.
- Custom extension ClientHello parsing callbacks also cannot depend on
resumption state.
- The DoS protection callback now runs after all the extension callbacks
as it is documented to be called after the resumption decision.

The distinction for full handshakes is not meaningful (the timestamp is
currently the start of the handshake), but for renewed sessions, we
currently retain the timestamp of the original issuance.
Instead, when minting or receiving tickets, adjust session->time and
session->timeout so that session->time is the ticket issuance time.
This is still not our final TLS 1.3 behavior (which will need a both
renewable and non-renewable times to honor the server ticket lifetime),
but it gets us closer and unblocks handling ticket_age_add from TLS 1.3
draft 18 and sends the correct NewSessionTicket lifetime.
This fixes the ticket lifetime hint which we emit on the server to
mirror the true ticket lifetime. It also fixes the TLS 1.3 server code
to not set the ticket lifetime hint. There is no need to waste ticket
size with it, it is no longer a "hint" in TLS 1.3, and even in the TLS
1.3 code we didn't fill it in on the server.

Macros need a healthy dose of parentheses to avoid expression-level
misparses. Most of this comes from the clang-tidy CL here:

Also switch most of the macros to use do { ... } while (0) to avoid all

MinGW has two different versions of printf. We want the format string
warnings to match. This silences some warnings in the Android build.
See:
https://sourceforge.net/p/mingw-w64/wiki2/gnu%20printf/
Note this assumes that, for external calls of these functions, the build
configuration of the consumer and BoringSSL match in this regard. (But
it doesn't actually matter because the issue is only on XP.)
