Subject: checkout: reject if the branch is already checked out elsewhere

checkout: reject if the branch is already checked out elsewhere

One branch obviously can't be checked out at two places (but detached
heads are ok). Give the user a choice in this case: --detach, -b
new-branch, switch branch in the other checkout first or simply 'cd'
and continue to work there.
