- Generalize the function ssl_setup() so that the certificate info

  are passed as an argument.

- Update the code in main/http.c to use the new interface
  (the diff is large but mostly mechanical, due to the name change of
  several variables);

- And since now it is trivial, implement "AMI over TLS", and document
  the possible options in manager.conf

- And since the test client (openssl s_client -connect host:port )
  does not generate \r\n as a line terminator, make get_input()
  also accept just a \n as a line terminator (Mac users: do you
  also need the \r-only version ?)
 
The option parsing in manager.conf is not very efficient, and needs
to be cleaned up and made similar to what we have in http.conf
