sshpeer: make instance attributes and methods internal

Peer types are supposed to conform to a formal interface defined by
peer.peerrepository and wireproto.wirepeer. Every "public" attribute on
*peer types makes it harder to understand what attributes are part
of the interface and what are instance specific.

This commit converts a number of "public" instance attributes and
methods on sshpeer to internal so they can't be confused to be part of
the peer API.

The URL-related instance attributes were introduced in 876333a295ff
in 2005. AFAICT most of them aren't used and could potentially be
removed. But I kept them around anyway.

I also reorded some code to make things slightly easier to read.

.. api::

   Rename attributes on sshpeer to reflect peer API

Differential Revision: https://phab.mercurial-scm.org/D331

Corrupt an hg repo with a pull started during an aborted commit
Create two repos, so that one of them can pull from the other one.

  $ hg init source
  $ cd source
  $ touch foo
  $ hg add foo
  $ hg ci -m 'add foo'
  $ hg clone . ../corrupted
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo >> foo
  $ hg ci -m 'change foo'

Add a hook to wait 5 seconds and then abort the commit

  $ cd ../corrupted
  $ echo "[hooks]" >> .hg/hgrc
  $ echo 'pretxncommit = sh -c "sleep 5; exit 1"' >> .hg/hgrc

start a commit...

  $ touch bar
  $ hg add bar
  $ hg ci -m 'add bar' &

... and start a pull while the commit is still running

  $ sleep 1
  $ hg pull ../source 2>/dev/null
  pulling from ../source
  transaction abort!
  rollback completed
  abort: pretxncommit hook exited with status 1
