Add support to opportunistic TLS

A lot of protocols provide the feature to upgrade their plain text
connections to an encrypted one, via some kind of "STARTTLS" command.

Add generic code to support this extension, and allow dissection of the
entire TLS handshake.

As an example, SMTP and FTP dissectors have been updated; similar logic
might be applied to IMAP, POP, OPENVPN...

Since this feature requires to process more packets per flow, add the
possibility to disable it.

Fix some log messages.

As a side effect, this commit fix also a memory leak found by
oss-fuzzer
