rebase: use @{upstream} if no upstream specified
'git rebase' without arguments is currently not supported. Make it default to 'git rebase @{upstream}'. That is also what 'git pull [--rebase]' defaults to, so it only makes sense that 'git rebase' defaults to the same thing. Defaulting to @{upstream} will make it possible to run e.g. 'git rebase -i' without arguments, which is probably a quite common use case. It also improves the scenario where you have multiple branches that rebase against a remote-tracking branch, where you currently have to choose between the extra network delay of 'git pull' or the slightly awkward keys to enter 'git rebase @{u}'. The error reporting when no upstream is configured for the current branch or when no branch is checked out is reused from git-pull.sh. A function is extracted into git-parse-remote.sh for this purpose.
