Migrate tests in uniport-test.js to cpp/jtx. Handle exceptions in
WSClient and JSONRPClient constructors. Use shorter timeout
for HTTP and WS Peers when client is localhost. Add missing call to
start_timer in HTTP Peer. Add incomplete WS Upgrade request test
to prove that server timeout is working.
* Make HTTP(S) requests on websocket ports reply with Status page
* Fix isWebsocketUpgrade to compare case insensitive
* Make websocket upgrades with no websocket protocols configured report error
* Create unit test for unauthorized requests and the status page
