BoringSSL depends on the platform's locking APIs to make internal global
state thread-safe, including the PRNG. On some single-threaded embedded
platforms, locking APIs may not exist, so this dependency may be disabled
with a build flag.
Doing so means the consumer promises the library will never be used in any
multi-threaded address space. It causes BoringSSL to be globally thread-unsafe.
Setting it inappropriately will subtly and unpredictably corrupt memory and
leak secret keys.
Unfortunately, folks sometimes misinterpreted OPENSSL_NO_THREADS as skipping an
internal thread pool or disabling an optionally extra-thread-safe mode. This is
not and has never been the case. Rename it to
OPENSSL_NO_THREADS_CORRUPT_MEMORY_AND_LEAK_SECRETS_IF_THREADED to clarify what
this option does.
Update-Note: As a first step, this CL makes both OPENSSL_NO_THREADS and
OPENSSL_NO_THREADS_CORRUPT_MEMORY_AND_LEAK_SECRETS_IF_THREADED work. A later CL
will remove the old name, so migrate callers after or at the same time as
picking up this CL.

Providing a size hint to the allocator is substantially faster,
especially as we already know/need the size for OPENSSL_cleanse.
We provide a weak symbol that falls back to free when a malloc with
sdallocx is not statically linked with BoringSSL.
Alternatives considered:
* Use dlsym(): This is prone to fail on statically linked binaries
without symbols. Additionally, the extra indirection adds call
overhead above and beyond the linker resolved technique we're using.
* Use CMake rules to identify whether sdallocx is available: Once the
library is built, we may link against a variety of malloc
implementations (not all of which may have sdallocx), so we need to
have a fallback when the symbol is unavailable.

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.
