- It's too early to free the SSL object in 'vio_ssl_close'. There
   might still be a thread using or reading from it on platforms
   where we need to close the active connection/socket in order
   to break the read.  
 - Add new function 'vio_ssl_delete' and install it as the viodelete
   function for SSL connections.
