LibHTTP+LibTLS: Better HTTPS Socket EOF detection

Browse source 
When the server doesn't signal the Content-Length or use a chunked mode,
it may just terminate the connection after sending the data.
The TLS sockets would then get stuck in a state with no data to read and
not reach the disconnected state, making some requests hang.

We know double check the EOF status of HTTP jobs after reading the
payload to resolve requests properly and also mark the TLS sockets as
EOF after processing all the data and the underlying TCP socket reaches
EOF.

Fixes #12866.
