Mirroring all Gerrit repos in Phabricator with Diffusion is a goal in itself, not directly tied to #code-review , that would allow us to deprecate Gitblit (http://git.wikimedia.org/).
We need to make sure that there is a way to turn these mirrored repositories into Phabricator local repositories, in order to allow a smooth future migration from Gerrit.

Now that all repos are publicly available, update:
* all template links to GitHub for core (easy, same URL structure: [[https://www.mediawiki.org/w/index.php?title=Template:MW_file&diff=prev&oldid=1370782|{{MW file}} done]], ...)
* same, for extensions (how to get callsigns?)
* non-template links to GitHub for core
* non-template links to GitHub for extensions
Links to gitblit will be handled with redirects, see the specific task for that.
