epriestley a7376624b4 Allow arc to identify repositories without "project_id" ... Summary: Ref T4343. Continues the process of reducing the prominence of Arcanist Projects. Primarily: - Query Phabricator to identify the working copy based on explicit configuration, or guess based on heuristics. - Enhance `arc which` to explain the process to the user. - The `project_id` key is no longer required in `.arcconfig`. Minor/cleanup changes: - Rename `project_id` to `project.name` (consistency, clarity). - Rename `conduit_uri` to `phabricator.uri` (consistency, clairty). - These both need documentation updates. - Add `repository.callsign` to explicitly bind to a repository. - Updated `.arcconfig` for the new values. - Fix a unit test which broke a while ago when we fixed a rare definition of "unstaged". - Make `getRepositoryUUID()` generic so we can get rid of one `instanceof`. Test Plan: - Ran `arc which`. - Ran `arc diff`. - This doesn't really change anything, so the only real risk is version compatibility breaks. This //does// introduce such a break, but the window is very narrow: if you upgrade `arc` after this commit, and try to diff against a Phabricator which was updated after yesterday (D8068) but before D8072 lands, the lookup will work so we'll add `repositoryPHID` to the `differential.creatediff` call, but it won't exist in Phabricator yet. This window is so narrow that I'm not going to try to fix it, as I'd guess there is a significant chance that no users will be affected. I don't see a clever way to fix it that doesn't involve a lot of work, either.
