Plugin resource loads currently don't use nsIContentPolicy.shouldProcess, which means that we don't have MIME type data for them. This patch fixes that and is necessary for the experiment in bug 1108668.

Comment on attachment 8546021 [details] Reviewboard request Approval Request Comment [Feature/regressing bug #]: API needed for the experiment in bug 1108668 [User impact if declined]: Can't run the experiment [Describe test coverage new/current, TBPL]: Manually verified with the experiment code [Risks and why]: There is a risk that nsIContentPolicy implementations will see new notifications that they didn't expect and will somehow fail. I judge this risk as fairly low, and is mainly a risk with addons. [String/UUID change made/needed]: None

Backed out for failures in test_streamNotify.html: https://treeherder.mozilla.org/logviewer.html#?job_id=5277932&repo=mozilla-inbound https://treeherder.mozilla.org/logviewer.html#?job_id=5278924&repo=mozilla-inbound https://hg.mozilla.org/integration/mozilla-inbound/rev/157873c02e6d

This also failed with this patch: https://treeherder.mozilla.org/logviewer.html#?job_id=5280947&repo=mozilla-inbound

https://hg.mozilla.org/integration/fx-team/rev/621fadc8702b I had to move the code later in the method so that error returns triggered notifications properly.
