Subject: Prepare to provide stubbed out versions for reading/writing 0-RTT
 data

We do not support this feature but need to provide OpenSSL's API since
software assumes it's available whenever TLS1_3_VERSION is available.
These are minimal stubs that should have a decent chance to interact
reasonably with software expecting the tricky upstream semantics, but
this will have to be sorted out with runtime testing, so will likely
have to be refined and revisited.
