git branch / git checkout -b now honor --track when the upstream branch
is local. Previously --track was silently ignored for local upstream
branches.
The configuration setting branch.autosetupmerge can now be set to
"always" which is equivalent to using --track. Setting
branch.autosetupmerge to boolean true will retains the former behavior
of only setting up branch.*.merge for remote upstream branches.
Includes test cases for the new functionality.

- I broke out the documentation changes into a separate patch.
- Incorporated Johannes' suggested change to setup_tracking().
- Incorporated Junio's suggestion that explicit --track should cause a
failure when the starting point is not a branch.
