sync: Handle tag ref in "upstream" field

repo sync only handles a git tag properly when it is in the "revision"
field. However, "revision locked manifests" (`repo manifest
--revision-as-HEAD`) specifies the tag in the "upstream" field. The
issue is that this tag is not fetched. Only the commit that the tag
points to is fetched. This cases issues as
self._CheckForImmutableRevision() runs and comes to the conclusion that
the tag was changed while in fact, it was just not fetched. This causes
a full sync.

File docs/manifest-format.md, section Element-project:
> Attribute upstream: Name of the Git ref in which a sha1 can be found.
Used when syncing a revision locked manifest in -c mode to avoid having
to sync the entire ref space. Project elements not setting their own
upstream will inherit this value.

repo

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

Contact

Please use the repo-discuss mailing list or issue tracker for questions.

You can file a new bug report under the “repo” component.

Please do not e-mail individual developers for support. They do not have the bandwidth for it, and often times questions have already been asked on repo-discuss or bugs posted to the issue tracker. So please search those sites first.

Install

Many distros include repo, so you might be able to install from there.

# Debian/Ubuntu.
$ sudo apt-get install repo

# Gentoo.
$ sudo emerge dev-vcs/repo

You can install it manually as well as it's a single script.

$ mkdir -p ~/.bin
$ PATH="${HOME}/.bin:${PATH}"
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
$ chmod a+rx ~/.bin/repo
