If y is zero, there is no point with odd y, so the odd bit may not be
set, hence EC_R_INVALID_COMPRESSION_BIT. This code instead computed the
Kronecker symbol of x and changed the error code to
EC_R_INVALID_COMPRESSED_POINT if not a square.
As the comment says, this was (intended to be) unreachable. But it
seems x was a typo for tmp1. It dates to before upstream's
6fb60a84dd1ec81953917e0444dab50186617432, when BN_mod_sqrt gave
garbage if its input was not square. Now it emits BN_R_NOT_A_SQUARE.
Upstream's 48fe4d6233ac2d60745742a27f820dd88bc6689d then mapped
BN_R_NOT_A_SQUARE to EC_R_INVALID_COMPRESSED_POINT.

This changes our resumption strategy. Before, we would negotiate ciphers
only on fresh handshakes. On resumption, we would blindly use whatever
was in the session.
Instead, evaluate cipher suite preferences on every handshake.
Resumption requires that the saved cipher suite match the one that would
have been negotiated anyway. If client or server preferences changed
sufficiently, we decline the session.
This is much easier to reason about (we always pick the best cipher
suite), simpler, and avoids getting stuck under old preferences if
tickets are continuously renewed. Notably, although TLS 1.2 ticket
renewal does not work in practice, TLS 1.3 will renew tickets like
there's no tomorrow.
It also means we don't need dedicated code to avoid resuming a cipher
which has since been disabled. (That dedicated code was a little odd
anyway since the mask_k, etc., checks didn't occur. When cert_cb was
skipped on resumption, one could resume without ever configuring a
certificate! So we couldn't know whether to mask off RSA or ECDSA cipher
suites.)
Add tests which assert on this new arrangement.

This is in preparation for determining the cipher suite (which, in TLS
1.2, requires the certificate be known) before resumption.
Note this has caller-visible effects:
- cert_cb is now called whether resumption occurs or not. Our only
consumer which uses this as a server is Node which will require a
patch to fix up their mucking about with SSL_get_session. (But the
patch should be quite upstreamable. More 1.1.0-compatible and
generally saner.)
- cert_cb is now called before new_session_cb and dos_protection_cb.

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.

Having that logic in two different places is a nuisance when we go to
add new checks like resumption stuff. Along the way, this adds missing
tests for the ClientHello cipher/session consistency check. (We'll
eventually get it for free once the cipher/resumption change is

This also fixes a bug where the session validity checks happened in the
wrong order relative to whether tickets_supported or renew_ticket was
looked at. Fix that by lifting that logic closer to the handshake.
