It's never called in outside code. This too seems to be a remnant of the DSA
PKIX optional parameter stuff. This is confirmed both by a removed comment and
by the brief documentation at http://www.umich.edu/~x509/ssleay/x509_pkey.html
RFC 5480 does not allow ECDSA keys to be missing parameters, so this logic is
incorrect for ECDSA anyway. It was also failing to check
EVP_PKEY_copy_parameters' return value. And that logic looks pretty suspect if
you have a chain made up multiple certificate types.

I found no users of this. We can restore it if needbe, but I don't expect
anyone to find it useful in its current form. The API is suspect for the same
reasons DTLSv1_listen was. An SSL object is stateful and assumes you already
have the endpoint separated out.
If we ever need it, server-side HelloVerifyRequest and DTLSv1_listen should be
implemented by a separate stateless listener that statelessly handles
cookieless ClientHello + HelloVerifyRequest. Once a ClientHello with a valid
cookie comes in, it sets up a stateful SSL object and passes control along to
that.

Previously, error strings were kept in arrays for each subdirectory and
err.c would iterate over them all and insert them at init time to a hash
table.
This means that, even if you have a shared library and lots of processes
using that, each process has ~30KB of private memory from building that
hash table.
This this change, all the error strings are built into a sorted list and
are thus static data. This means that processes can share the error
information and it actually saves binary space because of all the
pointer overhead in the old scheme. Also it saves the time taken
building the hash table at startup.
This removes support for externally-supplied error string data.

OpenSSL's internal names for the ciphers are not the standard ones and are not
easy to consistently map to the standard ones. Add an API to get the real names
out. (WebRTC wants an API to get the standard names out.)
Also change some incorrect flags on SHA-256 TLS 1.2 ciphers;
SSL_HANDSHAKE_MAC_DEFAULT and SSL_HANDSHAKE_MAC_SHA256 are the same after TLS
1.2. A TLS 1.2 cipher should be tagged explicitly with SHA-256. (This avoids
tripping a check in SSL_CIPHER_get_rfc_name which asserts that default-hash
ciphers only ever use SHA-1 or MD5 for the bulk cipher MAC.)

This makes the following changes:
- SSL_cutthrough_complete no longer rederives whether cutthrough happened and
just maintains a handshake bit.
- SSL_in_init no longer returns true if we are False Starting but haven't
completed the handshake. That logic was awkward as it depended on querying
in_read_app_data to force SSL_read to flush the entire handshake. Defaulting
SSL_in_init to continue querying the full handshake and special-casing
SSL_write is better. E.g. the check in bidirectional SSL_shutdown wants to know
if we're in a handshake. No internal consumer of
SSL_MODE_HANDSHAKE_CUTTHROUGH ever queries SSL_in_init directly.
- in_read_app_data is gone now that the final use is dead.

This is so the tests needn't be sensitive to the clock. It is, unfortunately, a
test-only hook, but the DTLS retransmit/timeout logic more-or-less requires it
currently. Use this hook to, for now, freeze the clock at zero. This makes the
tests deterministic.
It might be worth designing a saner API in the future. The current one,
notably, requires that the caller's clock be compatible with the one we
internally use. It's also not clear whether the caller needs to call
DTLSv1_handle_timeout or can just rely on the state machine doing it internally
(as it does do). But mock clocks are relatively tame and WebRTC wants to
compile against upstream OpenSSL for now, so we're limited in how much new API
we can build.
