[PATCH v2 0/8] Initial Python 3 support

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 v1:

* rebased on master after fc/remote-testgit-feature-done was merged,
  leading to an extra change in patch 8 (git-remote-testpy: call print
  as a function)
* changed patch 2 (git_remote_helpers: fix input when running under
  Python 3) to treat ref names as byte strings

John Keeping (8):
  git_remote_helpers: Allow building with Python 3
  git_remote_helpers: fix input when running under Python 3
  git_remote_helpers: Force rebuild if python version changes
  git_remote_helpers: Use 2to3 if building with Python 3
  svn-fe: allow svnrdump_sim.py to run with Python 3
  git-remote-testpy: hash bytes explicitly
  git-remote-testpy: don't do unbuffered text I/O
  git-remote-testpy: call print as a function
