Return to the proper TLSv1.2 record format with true ContentTypes
(hiding them doesn't add any security anyways).

With the needlessly broken ContentTypes, we will be unable to support
TLSv1.3 in our current apps.

The needless changes break streaming of layered IO and end-of-communication
discovery for long-running requests, because it is not possible to
reliably distinguish a warning-level closure alert from a pipelined
continuation of app data.
