Since Bazel doesn't have a shared vs static concept that's exposed to
the build rules (as far as I know) symbol visibility would mean that the
symbols might be exposed when building a larger library. That could be
fixed with a linker script, but this change appears to be slightly more
useful for our consumers.
(Also, if we're going to set -fvisibility=hidden, we should also have set
the defines needed to include the visibility annotations.)

Both DTLS and TLS still use it, but that will change in the following
commit. This also removes the handshake's knowledge of the
dtls_clear_incoming_messages function.
(It's possible we'll want to get rid of begin_handshake in favor of
allocating it lazily depending on how TLS 1.3 post-handshake messages
end up working out. But this should work for now.)

V2ClientHello is going to be ugly wherever we do it, but this hides it
behind the transport method table. It removes a place where the
handshake state machine reaches into ssl3_get_message's internal state.
ssl3_get_message will now silently translate V2ClientHellos into true
ClientHellos and manage the handshake hash appropriately.
Now the only accesses of init_buf from the handshake state machines are
to create and destroy the buffer.

As with the client, the logic around extensions in 1.3 will want to be

it'll get a bit unwieldy once HelloRetryRequest, PSK resumption, and
