I have added extensive test coverage to the patch stack that hooks up the DNR engine with the network (bug 1745761), except for StreamFilter.

Although trivial to write, I'm separating them from the main patch because StreamFilter tests have historically been causes for intermittent test failures for reasons unrelated to the original test. Debugging / triaging such failures would be easier when the test is isolated.

Most streamfilter tests have some form of skip-if in https://searchfox.org/mozilla-central/rev/83b86005c6913c2062419efb8aabdf2e683aa47f/toolkit/components/extensions/test/xpcshell/xpcshell-common-e10s.ini#4-20.

Note: these tests should ideally be moved to xpcshell-common.ini from xpcshell-common-e10s.ini, but that's covered by bug 1724094.
