The goal in this series is to pass t3200 with SANITIZE=leak.

As a result of the fixes, other tests also pass.

This is the list of tests that no longer trigger any leak after this
series:

   + t1507-rev-parse-upstream.sh
   + t1508-at-combinations.sh
   + t1514-rev-parse-push.sh
   + t2027-checkout-track.sh
   + t3200-branch.sh
   + t3204-branch-name-interpretation.sh
   + t5404-tracking-branches.sh
   + t5517-push-mirror.sh
   + t5525-fetch-tagopt.sh
   + t6040-tracking-info.sh
   + t7508-status.sh

Each of the commits (except 5/5) fixes a leak.  They have no
dependencies on each other.  As a result, they can be reordered.

To review one leak, the commit can be moved to the tip or reverted.
E.g. to review: "branch: fix a leak in setup_tracking", this can
be used:

  $ git revert --no-edit HEAD~3
  $ make SANITIZE=leak test T=t3200-branch.sh

Also, each commit have a minimal script in the message that can be used
to reproduce the leak.

This is the second version of this series.  However, a subset of the
patches from the first version have already been merged to 'next'.
Therefore, those are not included here.

These are the rest of them, which address Peff's reviews.

Thanks.
