evolve: store the obsmarkers to be deleted in evolvestate

Sometimes, we don't create a new node and obsolete one of the old node in favour
of an existing node. When user calls, `hg evolve --abort`, we need to strip that
obsmarker to go back in the same old state. The obsmarker created for new node
are stripped when the new nodes are stripped.

This patch start storing such obsmarkers in the evolvestate so that we can delete
them later if required. Right now we just store successsor and predecessor
information, we might need a better obsmarker serialization techinque in future
to make it more robust.

Check we can find the topic extensions

Create a simple setup

  $ hg init repoa

  $ mkcommit aaa

  $ hg topic foo
  marked working directory as topic: foo
  $ mkcommit ccc
  active topic 'foo' grew its first changeset

  $ mkcommit fff
  $ hg topic bar
  $ mkcommit ggg
  active topic 'bar' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit hhh
  $ mkcommit iii
