Subject: [PATCH] Use Gitea for Gerrit's code browser URLs

This is a reimplementation of earlier change
I8efefe365f3b9ebe97c8c2ce322fa8c6f3b70b3a to link out to Gitea
instead of Gerrit's local Gitiles plugin. This should reduce the
complexity of what we're hosting on the Gerrit server, while at the
same time be less confusing for search engines and users. Configure
the Gitiles plugin to no longer take over Gerrit weblinks, and a
followup change will block access to its URL base path entirely.
