obsolete: explicitly track folds inside the markers

We now record information to be able to recognize "fold" event from
obsolescence markers. To do so, we track the following pieces of information:

a) a fold ID. Unique to that fold (per successor),
b) the number of predecessors,
c) the index of the predecessor in that fold.

We will now be able to create an algorithm able to find "predecessorssets".

We now store this data in the generic "metadata" field of the markers.
Updating the format to have a more compact storage for this would be useful.

This way of tracking a fold through multiple markers could be applied to split
too. This would have two advantages:

1) We get a simpler format, since number of successors is limited to [0-1].
2) We can better deal with situations where only some of the split successors
   are pushed to a remote repository.

We should look into the relevance of such a change before updating the on-disk
format.

note: unlike splits, folds do not have to deal with cases where only some of
the markers have been synchronized. As they all share the same successor
changesets, they are all relevant to the same nodes.

Error is handled reasonably. We override the phabtoken here so that
when you're developing changes to phabricator.py you can edit the
above config and have a real token in the test but not have to edit
this test.
  $ hg phabread --config auth.hgphab.phabtoken=cli-notavalidtoken \

  abort: Conduit Error (ERR-INVALID-AUTH): API token "cli-notavalidtoken" has the wrong length. API tokens should be 32 characters long.

Basic phabread:

  # HG changeset patch
  exchangev2: start to implement pull with wire protocol v2
  
  Wire protocol version 2 will take a substantially different
  approach to exchange than version 1 (at least as far as pulling
  is concerned).
  
  This commit establishes a new exchangev2 module for holding
  code related to exchange using wire protocol v2. I could have
  added things to the existing exchange module. But it is already

phabupdate with an accept:
  $ hg phabupdate --accept D4564 \
  > -m 'I think I like where this is headed. Will read rest of series later.'\
