Bug #14822: [POP3/SSL] net/protocol.rb:44: warning: verify_hostname requires hostname to be set

When enabling SSL with POP3 like this:

require 'net/pop'

Net::POP.enable_ssl
Net::POP3.start(...) |pop|
...

A warning like this will be generated:
net/protocol.rb:44: warning: verify_hostname requires hostname to be set

This happens because SSLContext default is :verify_hostname => true.

The attached patch fixes this by setting the SSLSocket#hostname variable to the address which is given during Net::POP3.start.

I can reproduce this issue, and have confirmed your fix removes the warning. It would have been helpful to mention that this warning is only printed in verbose mode. :)
