setup: tweak error message for Python 3

We now have beta support for Python 3. In my opinion, it isn't
yet stable enough to allow `pip install Mercurial` to work with
Python 3 out of the box: we don't want people accidentally using
Mercurial with Python 3 just yet.

But I do think we should be more friendly about informing people
of their options.

This commit tweaks the error message that users see when running
setup.py with Python 3. We instruct them about the current level
of Python 3 support, point them at the wiki for more info, and
give them instructions on how to bypass the check.

As part of this, I also changed which version value is printed,
as we were printing a named tuple before.

Test backup-bundle config option |
==================================
Test with Pre-obsmarker rebase:
1) When config option is not set:
  $ hg init repo1
  $ cd repo1
  $ echo a>a
  $ hg ci -qAma
  $ echo b>b
  $ hg ci -qAmb
  $ echo c>c
  $ hg ci -qAmc
  $ hg up 0 -q
  $ echo d>d
  $ hg ci -qAmd
  $ echo e>e
  $ hg ci -qAme
  $ hg log -GT "{rev}: {firstline(desc)}\n"
  @  4: e
  |
  o  3: d
  |
  | o  2: c
  | |
  | o  1: b
  |/
  o  0: a
  
  $ hg rebase -s 1 -d .
  rebasing 1:d2ae7f538514 "b"
  rebasing 2:177f92b77385 "c"
  saved backup bundle to $TESTTMP/repo1/.hg/strip-backup/d2ae7f538514-c7ed7a78-rebase.hg
  $ hg log -GT "{rev}: {firstline(desc)}\n"
  o  4: c

Test when rebased revisions are stripped during abort:
======================================================

  $ echo conflict > c
  $ hg ci -Am "conflict with c"
  adding c
  created new head
  $ hg log -GT "{rev}: {firstline(desc)}\n"
  @  7: conflict with c
