sshpeer: implement peer for version 2 of wire protocol

Since the protocol is now negotiated before we construct a
peer instance, we can return the negotiated protocol from the
handshake function and instantiate an appropriate peer class
for the protocol.

Version 2 of the SSH protocol is currently identical to version
1 post handshake. So our sshv2peer class just inherits from
sshv1peer for the time being. This will obviously change
over time.

====================================
Testing head checking code: Case B-7
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category B: simple case involving pruned changesets
TestCase 7: single changesets, pruned then superseeded (on an existing changeset)

.. old-state:
..
.. * 1 changeset branch
..
.. new-state:
..
.. * old branch is rewritten onto the common set,
.. * the new version is then pruned.
..
.. expected-result:
..
.. * push allowed

Actual testing
--------------

  $ hg push
  pushing to $TESTTMP/B7/server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)
  2 new obsolescence markers
  obsoleted 1 changesets
