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.

  $ hg amend -h
  hg amend [OPTION]... [FILE]...
  
  aliases: refresh
  
  combine a changeset with updates and replace it with a new one
  
      Commits a new changeset incorporating both the changes to the given files
      and all the changes from the current parent changeset into the repository.
  
      See 'hg commit' for details about committing changes.
  
      If you don't specify -m, the parent's message will be reused.
  
      If --extract is specified, the behavior of 'hg amend' is reversed: Changes
      to selected files in the checked out revision appear again as uncommitted
      changed in the working directory.
  
      Returns 0 on success, 1 if nothing changed.
  
  options ([+] can be repeated):
  
   -A --addremove           mark new/missing files as added/removed before
