/**
* Asynchronously prompt the user for a username and password.
* This has largely the same semantics as promptUsernameAndPassword(),
* but must return immediately after calling and return the entered
* data in a callback.
*
* If the user closes the dialog using a cancel button or similar,
* the callback's nsIAuthPromptCallback::onAuthCancelled method must be
* called.
* Calling nsICancelable::cancel on the returned object SHOULD close the
* dialog and MUST call nsIAuthPromptCallback::onAuthCancelled on the provided
* callback.
*
* This implementation may:
*
* 1) Coalesce identical prompts. This means prompts that are guaranteed to
* want the same auth information from the user. A single prompt will be
* shown; then the callbacks for all the coalesced prompts will be notified
* with the resulting auth information.
* 2) Serialize prompts that are all in the same "context" (this might mean
* application-wide, for a given window, or something else depending on
* the user interface) so that the user is not deluged with prompts.
*
* @throw
* This method may throw any exception when the prompt fails to queue e.g
* because of out-of-memory error. It must not throw when the prompt
* could already be potentially shown to the user. In that case information
* about the failure has to come through the callback. This way we
* prevent multiple dialogs shown to the user because consumer may fall
* back to synchronous prompt on synchronous failure of this method.
