for-each-ref: add "upstream" format field
The logic for determining the upstream ref of a branch is
somewhat complex to perform in a shell script. This patch
provides a plumbing mechanism for scripts to access the C
logic used internally by git-status, git-branch, etc.
For example:
$ git for-each-ref \
--format='%(refname:short) %(upstream:short)' \
refs/heads/
master origin/master
