Previously, the |CRYPTO_BUFFER|-based methods always rejected
certificate chains because none of the current callbacks is suitable to
use. In the medium-term, we want an async callback for this but, for
now, we would like to get Chromium working. Chromium already installs a
no-op callback (except for the logic that was moved into BoringSSL in
a58baaf9e6) and so this hack will suffice
for Chromium.

On 32-bit x86, |bn_mul_mont| returns 0 when the modulus has less than
four limbs. Instead of calling |bn_mul_mont| and then falling back to
the |BN_mul|+|BN_from_montgomery_word| path for small moduli, just
avoid calling |bn_mul_mont| at all for small moduli.
This allows us to more clearly understand exactly when the fallback
code path, which is a timing side channel, is taken. This change makes
it easier to start minimizing this side channel.
The limit is set at 128 bits, which is four limbs on 32-bit and two
limbs on 64-bit platforms. Do this consistently on all platforms even
though it seems to be needed only for 32-bit x86, to minimize platform
variance: every platform uses the same cut-off in terms of input size.
128 bits is small enough to allow even questionably small curves, like
secp128r1, to use the |bn_mul_mont| path, and is way too small for RSA
and FFDH, so this change shouldn't have any security impact other than
the positive impact of simplifying the control flow.

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.

1. The public API now queries it out of the session. There is a long
comment over the old field explaining why the state was separate, but
this predates EMS being forbidden from changing across resumption. It
is not possible for established_session and the socket to disagree on
EMS.
2. Since SSL_HANDSHAKE gets reset on each handshake, the check that EMS
does not change on renego looks different. I've reworked that function a
bit, but it should have the same effect.
