is required. Fedora 30 will be EOL within the next 6 weeks.
Ubuntu 14.04 is no longer receiving upstream support: https://www.omgubuntu.co.uk/2019/04/ubuntu-14-04-end-of-life

Drive-by refactoring of some unsafe code in stylo
Some stuff I found while thinking about other things between stylo and layout.
Third commit requires Gecko changes because I removed `From<u32>` for `FontLanguageOverride` and replaced it by the unsafe `FontLanguageOverride::from_u32` method.

There is no need to set the dirty descendants flag unsafely from the layout side
for elements with pending restyles, we can do that on the DOM side when draining
the restyles from the Document.
Check the BHM option before starting it in multi-process mode.
In multi-process mode, if the BHM option is set start with one otherwise don't.
I didn't add a test for this. However if I should I'd be happy to be pointed to where similar tests are done (meaning tests of options yielding the expected state) because I didn't find my way in all those tests.

problems inside webrender.
