[issue4473] POP3 missing support for starttls

[Lorenzo M. Catucci]

New submission from Lorenzo M. Catucci <lorenzo at sancho.ccd.uniroma2.it>:

In the enclosed patch, there are four changes 
1. add support for the optional CAPA pop command, since it is needed
   for starttls support discovery
2. add support for the STLS pop command
3. replace home-grown file-like methods and replace them with ssl
   socket's makefile() in POP3_SSL
4. Properly shutdown sockets at close() time to avoid server-side pile-up
