One tedious thing about using CBB is that you can't safely CBB_cleanup
until CBB_init is successful, which breaks the general 'goto err' style
of cleanup. This makes it possible:
CBB_zero ~ EVP_MD_CTX_init
CBB_init ~ EVP_DigestInit
CBB_cleanup ~ EVP_MD_CTX_cleanup

Use more sensible variable names. Also move some work between the helpers and
s3_srvr.c a little; the session lookup functions now only return a new session.
Whether to send a ticket is now an additional output to avoid the enum
explosion around renewal. The actual SSL state is not modified.
This is somewhat cleaner as s3_srvr.c may still reject a session for other
reasons, so we avoid setting ssl->session and ssl->verify_result to a session
that wouldn't be used. (They get fixed up in ssl_get_new_session, so it didn't
actually matter.)

Chromium uses a zygote process and a sandbox on Linux. In order for RAND_bytes
to be functional and guaranteed fork-safe inside the renderers, /dev/urandom
must be prewarmed. Calling RAND_bytes initializes a thread-local ChaCha20 key
when rdrand is available. So that key is fork-safe and to avoid tempting any
dragons by touching pthreads APIs before a non-exec fork, add a
RAND_set_urandom_fd API. It allows the consumer to supply the /dev/urandom fd
and promises to be fork-safe, both in initializing key material and use of
pthreads.
This doesn't affect any current shipping versions of Chrome.

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.
