Kris Maglione 94e3b0bd8d Bug 1596918: Part 3a - Scripted rewrite of most ContentTask.spawn calls to SpecialPowers.spawn calls. r=mccr8,remote-protocol-reviewers,ato
This is generally pretty straightforward, and rewrites nearly all calls. It
skips the ones that it can detect using frame script globals like
`sendAsyncMessage`, though.
