Bug 96459, bug 96307 and Bugscape 8288. Implement readyState and onreadystatechange members to enable progress indicators for download. Make it possible to call send() again in onload without crashing. Send load event only after everything done (was sent too early if XML errors). Make some functions throw error if called at the wrong time (match IE). Make it possible to build SOAP again (patch from peterv, r=heikki). r=harishd, sr=vidur, a=asa.

/**
* Mozilla's XMLHttpRequest is modelled after Microsoft's IXMLHttpRequest
* object. The goal has been to make Mozilla's version match Microsoft's
* version as closely as possible, but there are bound to be some differences.
*
* In general, Microsoft's documentation for IXMLHttpRequest can be used.
* Mozilla's interface definitions provide some additional documentation. The
* web page to look at is http://www.mozilla.org/xmlextras/
*
* Mozilla's XMLHttpRequest object can be created in JavaScript like this:
* new XMLHttpRequest()
* compare to Internet Explorer:
* new ActiveXObject("Msxml2.XMLHTTP")
*
* From JavaScript, the methods and properties visible in the XMLHttpRequest
* object are a combination of nsIXMLHttpRequest and nsIJSXMLHttpRequest;
* there is no need to differentiate between those interfaces.
*
* From native code, the way to set up onload and onerror handlers is a bit
* different. Here is a comment from Johnny Stenback <jst@netscape.com>:
*
* The mozilla implementation of nsIXMLHttpRequest implements the interface
* nsIDOMEventTarget and that's how you're supported to add event listeners.
* Try something like this:
*
* nsCOMPtr<nsIDOMEventTarget> target(do_QuertyInterface(myxmlhttpreq));
*
* target->AddEventListener(NS_LITERAL_STRING("load"), mylistener,
* PR_FALSE)
*
* where mylistener is your event listener object that implements the
* interface nsIDOMEventListener.
*
* The 'onload' and 'onerror' attributes moved to nsIJSXMLHttRequest,
* but if you're coding in C++ you should avoid using those.
