MSAN is incompatible with hand-written assembly code. Previously we
required that OPENSSL_NO_ASM be set when building with MSAN, and the
CMake build would take care of this. However, with other build systems
it wasn't always so easy.
This change automatically disables assembly when the compiler is
configured for MSAN.

We're a far cry from the good old days when we just read from /dev/urandom

In particular, the threading logic is slightly non-trivial and probably worth
some basic sanity checks. Also write a fork-safety test, and test the
fork-unsafe-buffering path.
The last one is less useful right now, since fork-unsafe-buffering is a no-op
with RDRAND enabled (although we do have an SDE bot...), but it's probably
worth exercising the code in

Historically, OpenSSL filled in a fake session ID for ticket-only
client sessions. Conscrypt relies on this to implement some weird Java
API where every session has an ID and may be queried out of the client
session cache and, e.g., revoked that way.
(Note that a correct client session cache is not keyed by session ID and
indeed this allows one server to knock out another server's sessions by
matching session IDs. But existing APIs are existing APIs.)
For consistency between TLS 1.2 and TLS 1.3, as well as matching
OpenSSL's TLS 1.3 implementation, do the same in TLS 1.3. Note this
smooths over our cross-version resumption tests by allowing for
something odd: it is now syntactically possible to resume a TLS 1.3
session at TLS 1.2. It doesn't matter either way, but now a different
codepath rejects certain cases.

Historically, OpenSSL's modular exponentiation functions tolerated negative
moduli by ignoring the sign bit. The special case for a modulus of 1 should do
the same. That said, this is ridiculous and the only reason I'm importing this
is BN_abs_is_word(1) is marginally more efficient than BN_is_one() and we
haven't gotten around to enforcing positive moduli yet.
