Add "-www" option to server tool.

Browse Source 
Add a simple dumb webserver that responds with the session status for
any GET request. This option is intended to be used with -loop to
generate automated responses to requests and serves two purposes: (1)
test that application data from clients can be decrypted, (2) test that
clients can decrypt data from the server and (3) early data indicator.
