Expose upstream and dest-branch attributes through environment

Recent changes in ChromeOS Infra to ensure we're reading from
snapshot manifests properly have exposed several bugs in our
assumptions about manifest files.  Mainly that the revision field
for a project does _not_ have to refer to a ref, it can just be
a commit hash.

Several places assume that the revision field can be parsed as a
ref to get the branch the project is on, which isn't true.  To fix
this we need to be able to look at the upstream and dest-branch
attributes of the repo, so we expose them through the environment
variables set in `repo forall`.

Test: manual 'repo forall' run

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
