[PATCHv2 0/2] git p4: use "move" command for renames

Difference from v1:
    * Remove "tee" usage in t9814, just send output to a file
      and grep it directly.

Recent p4 supports a "move" command that records explicitly that a file was moved from one place to another. It can be changed a bit during the move, too. Use this feature, if it exists, when renames are detected.

Gary sent these patches months ago, and I've been sitting on them far too long. Was hoping to move some other work out first, but it was not ready.

These commits are on origin/next, as they depend on changes in pw/git-p4-tests that was merged into next on Jul 3. They do not conflict with the other series in flight, "notice Jobs: ...".
