[Daniel Berrange]

At very least we should also use 404 if given a invalid path

Title:
  websockets: Improve error messages

Status in QEMU:
  New

Bug description:
  Since 2.9 / 07e95cd529af345fdeea230913f68eff5b925bb6 , whenever the
  VNC websocket server finds an error with the incoming connection
  request, it just closes the socket with no further information.

  This makes figuring out what's wrong with the request nearly
  impossible.

  I would be nice if:

  * HTTP 400 were returned to the client, with an appropriate error message
  * Maybe something written to the log as well?

  Currently, I'm resorting to looking at my request and the websocket
  source and hoping I can figure out what's wrong.
