  Log Message:
  -----------
  Ensure that the SSL_rstate_string*() API works as they used to

We initialise the record layer rstate variable to ensure the
SSL_rstate_string*() APIs return values that are consistent with
previous versions.

Fixes #20808

  Log Message:
  -----------
  Correct the SSL_rstate_string*() APIs to match reality

The docs mentioned a "RD"/"read done" state that could be returned.
In practice that never happened, so update the docs to match
reality.
