Bugzilla github login support

I note that Mozilla’s bugzilla supports login with github. E.g. see the “Sign in with Github” button on:

Code looks to be at:

Although it seems to have required some set of changes outside that dir, too. E.g.:

…and there’s presumably others too.

I must say, it’s really quite unfortunate that the bugzilla that bugzilla uses for its bugs has diverged so far from upstream bugzilla. GithubAuth seems like it should be a plugin that’s shipped with bugzilla upstream, not something that’s private to b.m.o.

But, if someone’s feeling adventurous, it might be possible to integrate that extension into llvm’s bugzilla. Maybe.
