MSan works by instrumenting memory accesses in the compiler. Accesses from
uninstrumented code, such as assembly, are invisible to it. MSan will
incorrectly report reads from assembly-initialized memory as uninitialized.
To avoid confusing downstream consumers with false positives, catch this at
compile-time with a more useful error.
Update-Note: BoringSSL with MSan and assembly doesn't work, but now rather than
crashing at runtime, it will fail to build altogether. It's possible someone
was building BoringSSL with MSan and either not running it at all or just not
exercising the codepaths that break.

Otherwise, if the output BIGNUM was previously negative, we'd incorrectly give

Fortunately, this does not appear to come up in any existing caller. This isn't

Were it not for OpenSSL historically designing a calculator API, we'd just

Previously we used thread-local state objects in rand.c. However, for
applications with large numbers of threads, this can lead to excessive
memory usage.
This change causes us to maintain a mutex-protected pool of state
objects where the size of the pool equals the maximum concurrency of
|RAND_bytes|. This might lead to state objects bouncing between CPUs
more often, but should help the memory usage problem.

Previously we'd partially attempted the ssl_st / bssl::SSLConnection
subclassing split, but that gets messy when we actually try to add a
destructor, because CRYPTO_EX_DATA's cleanup function needs an ssl_st*,
not a bssl::SSLConnection*. Downcasting is technically undefined at this
point and will likely offend some CFI-like check.
Moreover, it appears that even with today's subclassing split,
New<SSL>() emits symbols like:
W ssl_st*& std::forward<ssl_st*&>(std::remove_reference<ssl_st*&>::type&)
The compiler does not bother emitting them in optimized builds, but it
does suggest we can't really avoid claiming the ssl_st type name at the
symbol level, short of doing reinterpret_casts at all API boundaries.
And, of course, we've already long claimed it at the #include level.
So I've just left this defining directly on ssl_session_st. The cost is
we need to write some silly "bssl::" prefixes in the headers, but so it
goes. In the likely event we change our minds again, we can always
revise this.

This partitions the session ID space of the internal cache by version,
which is nominally something we want, but we must check the version
externally anyway for both tickets and external session cache. That
makes this measure redundant. (Servers generate session IDs and 2^256 is
huge, so there would never accidentally be a collision.)
This cuts down on the "key" in the internal session cache, which will
simplify adding something like an lh_SSL_SESSION_retrieve_key function.
(LHASH is currently lax about keys because it can freely stack-allocate
partially-initialized structs. C++ is a bit more finicky about this.)
