81091d55e1 Don't use uninitialized memory in RAND_bytes.
We can't actually catch this with MSan because it requires all code be
instrumented, so it needs a NO_ASM build which no disables that code. valgrind
doesn't notice either, possibly because there's some computation being done on
it. Still, we shouldn't use uninitialized memory.

Also get us closer to being instrumentable by MSan, but the runner tests will
need to build against an instrumented STL and I haven't tried that yet.

3700778248 Fix Windows build failures caused by 310d4dd.
MSVC doesn't like |const size_t len| in a function definition where the
declaration was just |size_t len| without the |const|. Also, MSVC needs
declarations of parameterless functions to have a |void| parameter list.

c3ef76f327 Compatibility changes for wpa_supplicant and OpenSSH.
OpenSSH, especially, does some terrible things that mean that it needs
the EVP_CIPHER structure to be exposed ☹. Damian is open to a better API
to replace this, but only if OpenSSL agree too. Either way, it won't be
happening soon.
