In bug 1322517 we will remove support for EME in insecure contexts. We should add a warning when EME is used in insecure contexts, so authors have time to transition.

We have 1 day of data on the telemetry probe I added to determine what proportion of contexts where EME is used are insecure, and it's showing 15% of contexts are insecure.

Bug 1361000 - Log a deprecation warning to the web console upon use of EME in an insecure context.

https://reviewboard.mozilla.org/r/135100/#review138128

Does the console show which url (of the page, that is) is involved?   If not, please include it in the warning.

Backed out in https://hg.mozilla.org/integration/autoland/rev/a812a96caba2 - built nicely on Windows, but everything else failed like https://treeherder.mozilla.org/logviewer.html#?job_id=95817339&repo=autoland, "Navigator.cpp:2032:31: error: ignoring return value of 'nsresult nsIDocument::GetDocumentURI(nsString&) const', declared with attribute warn_unused_result [-Werror=unused-result]"
