Prevents access to request raw data in Flask #457

This all seems to be a bit of a mess, but if you want to access the raw request data in Flask regardless of the content type (I can't control the client), you need to call

 request.get_data()

and you need to do this before accessing request.data or request.form, because both of these will call get_data() in such a way that the stream will be exhausted, parsed into the form dict, and the raw data is never cached.

This doesn't seem documented except in the comments: https://github.com/mitsuhiko/werkzeug/blob/master/werkzeug/wrappers.py#L440

Should the sentry extension call request.get_data() first to make sure the raw data is cached before using request.form?
