Details:

-   Add persistent session support
    
    On connect, application can provide flags to start with a clean session.
    
    On CONNACK reception, forward the acknowledge information to application.
    
    Application can manage its subscribtion according of the received session
persistent flag.

- Allow TLS session save and reuse for faster connection
    
    Use the new `struct altcp_tls_session` type to store TLS session
information
    in application provided buffer to ease TLS session resuming in MQTT
client.

-   Send ack of received message before calling client data callback
    
    This is just in case application want to disconnect mqtt client once it
got its response.
    If disconnected inside this callback, ACK cannot be sent after!

-   Remove 64KB limit in ring buffer size


Depend on altcp_mbedtls patchset #9862.
