This removes EVP_PKEY_HMAC and all the support code around it. EVP_MD requires
a lot of extra glue to support HMAC. This lets us prune it all away.
As a bonus, it removes a (minor) dependency from EVP to the legacy ASN.1 stack.

I mistakenly believed that only RDSEED could fail. However, the Intel
manuals state that RDRAND can fail too.
I can't actually observe it failing, even with all cores running RDRAND in a
tight loop. In any case, the ChaCha20 masking means that it wouldn't be
a big deal anyway.
Still, this change tests the carry flag after RDRAND and the code falls
back to |CRYPTO_sysrand| if RDRAND has a hiccup. (The Intel manuals
suggest[1] calling RDRAND in a loop, ten times, before considering it to
have failed. But a single failure appears to be such a rare event that
the complexity in the asm code doesn't seem worth it.)
This change also adds an asm function to fill a buffer with random data.
Otherwise the overhead of calling |CRYPTO_rdrand|, and bouncing the data
in and out of memory starts to add up.
Thanks to W. Mark Kubacki, who may have reported this. (There's some
confusion in the bug report.)

Rather than rely on Chromium to query SSL_initial_handshake_complete in the
callback (which didn't work anyway because the callback is called afterwards),
move the logic into BoringSSL. BoringSSL already enforces that clients never
offer resumptions on renegotiation (it wouldn't work well anyway as client
session cache lookup is external), so it's reasonable to also implement
in-library that sessions established on a renegotiation are not cached.
Add a bunch of tests that new_session_cb is called when expected.

This adds a new API, SSL_set_private_key_method, which allows the consumer to

The new method is only routed up for the client for now. The server will

To account for the changes in ticket renewal, Chromium will need to listen for
new_session_cb to determine whether the handshake produced a new session.
Chromium currently never caches sessions produced on a renegotiation. To retain
that behavior, it'll need to know whether new_session_cb is initial or not.
Rather than maintain duplicate state and listen for SSL_HANDSHAKE_DONE, it's
simpler to just let it query ssl->s3->initial_handshake_complete.

Platform crypto APIs for PKCS#1 RSA signatures vary between expecting the
caller to prepend the DigestInfo prefix (RSA_sign_raw) and prepending it
internally (RSA_sign). Currently, Chromium implements sign or sign_raw as
appropriate. To avoid needing both variants, the new asynchronous methods will
only expose the higher-level one, sign.
To satisfy ports which previously implemented sign_raw, expose the DigestInfo
prefix as a utility function.

Rather than write a dup function, serializing and deserializing the object is
simpler. It also fixes a bug in the original fix where it never calls
new_session_cb to store the new session (for clients which use that callback;
how clients should handle the session cache is much less clear).
The old session isn't pruned as we haven't processed the Finished message yet.
RFC 5077 says:
The server MUST NOT assume that the client actually received the updated
ticket until it successfully verifies the client's Finished message.
Moreover, because network messages are asynchronous, a new SSL connection may
have began just before the client received the new ticket, so any such servers
are broken regardless.

that the top-level object won't be overridden.
