HttpResponse object should return self when write() method is called

[Jonathan Sawyer]

My use case:

# Current procedure
def myview(req):
    resp = HttpResponse(mimetype='application/javascript')
    resp.write(json.dumps({'msg': 'Hello World!'}))
    return resp

# Desired procedure
def myview(req):
    resp = HttpResponse(mimetype='application/javascript')
    return resp.write(json.dumps({'msg': 'Hello World!'}))

HttpResponse.write() returns None initially. It would be really nice if .write() would return self so I can return an HttpResponse object. Instead I have to take up an extra line of code (and in my application, that is a lot when duplicated).

An extension on this request could be that all public methods on HttpResponse should return self.

Patch to #16389 where self is returned on .write() method

Attached is my patch. I have tested this functionality and it works when objects use HttpResponse as file objects. As far as I know, this won't break python compatibility because on errors, exceptions are raised rather than the output being the form of an error code. Thanks in advance.
