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 Bug: https://crbug.com/1032441 Change-Id: I2c039e0f4b2e0f430602932e91b782edb6f9b1ed Reviewed-on: https://gerrit-review.googlesource.com/c/git-repo/+/263132 Reviewed-by: Mike Frysinger <vapier@google.com> Tested-by: Sean McAllister <smcallis@google.com>

The manifest and (if present) local_manifest.xml are combined

The -r option can be used to generate a manifest file with project

"revision locked manifests", as they don't follow a particular branch.

In this case, the 'upstream' attribute is set to the ref we were on
