[PATCH v3 0/8] Python 3 support for git_remote_helpers

This series does enough so that everything except git-p4 runs under
Python 3.
                                                                                 
As discussed with Pete, it may not make sense to change git-p4 to
support Python 3 until Perforce's Python output mode is changed.  So
does it make sense to merge this now and say "use Python 2 if you want
git-p4"?
                                                                                 
Changes since v2:

 - Change reference URL in commit message of patch 4
   (git_remote_helpers: Use 2to3 if building with Python 3) to point at
   Python documentation instead of the Python wiki.

 - Add a comment in patch 7 (git-remote-testpy: don't do unbuffered text
   I/O), as suggested by Sverre.
