branchmap: server should not advertise secret changeset in branchmap (Issue3303)

Discovery now use an overlay above branchmap to prune invisible "secret"
changeset from branchmap.

To minimise impact on the code during the code freeze, this is achieve by
recomputing non-secret heads on the fly when any secret changeset exists. This
is a computation heavy approach similar to the one used for visible heads. But
few sever should contains secret changeset anyway.  See comment in code for more
robust approach.

On local repo the wrapper is applied explicitly while the wire-protocol take
care of wrapping branchmap call in a transparent way. This could be unified by
the Peter Arrenbrecht and Sune Foldager proposal of a `peer` object.

An inappropriate `(+i heads)` may still appear when pushing new changes on a
repository with secret changeset. (see Issue3394 for details)

 This module implements most phase logic in mercurial.
 
 
 Basic Concept
 =============
 
 A 'changeset phases' is an indicator that tells us how a changeset is
 manipulated and communicated. The details of each phase is described below,
 here we describe the properties they have in common.
 
 Like bookmarks, phases are not stored in history and thus are not permanent and
 leave no audit trail.
 
 First, no changeset can be in two phases at once. Phases are ordered, so they
 can be considered from lowest to highest. The default, lowest phase is 'public'
 - this is the normal phase of existing changesets. A child changeset can not be
 in a lower phase than its parents.
 
 These phases share a hierarchy of traits:
 
             immutable shared
     public:     X        X
     draft:               X
     secret:
 
 local commits are draft by default
 
 Phase movement and exchange
 ============================
 
 Phase data are exchanged by pushkey on pull and push. Some server have a
 publish option set, we call them publishing server. Pushing to such server make
 draft changeset publish.
 
 A small list of fact/rules define the exchange of phase:
 
 * old client never changes server states
 * pull never changes server states
 * publish and old server csets are seen as public by client
 
 * Any secret changeset seens in another repository is lowered to at least draft
 
 
 Here is the final table summing up the 49 possible usecase of phase exchange:
 
                            server
                   old     publish      non-publish
                  N   X    N   D   P    N   D   P
     old client
     pull
      N           -   X/X  -   X/D X/P  -   X/D X/P
      X           -   X/X  -   X/D X/P  -   X/D X/P
     push
      X           X/X X/X  X/P X/P X/P  X/D X/D X/P
     new client
     pull
      N           -   P/X  -   P/D P/P  -   D/D P/P
      D           -   P/X  -   P/D P/P  -   D/D P/P
      P           -   P/X  -   P/D P/P  -   P/D P/P
     push
      D           P/X P/X  P/P P/P P/P  D/D D/D P/P
      P           P/X P/X  P/P P/P P/P  P/P P/P P/P
 
 Legend:
 
     A/B = final state on client / state on server
 
     * N = new/not present,
     * P = public,
     * D = draft,
     * X = not tracked (ie: the old client or server has no internal way of
           recording the phase.)
 
     passive = only pushes
 
 
     A cell here can be read like this:
 
     "When a new client pushes a draft changeset (D) to a publishing server
     where it's not present (N), it's marked public on both sides (P/P)."
 
 Note: old client behave as publish server with Draft only content
 - other people see it as public
 - content is pushed as draft

 A. Clone without secret changeset
 
 1.  cloning non-publishing repository
 (Phase should be preserved)
 
 # make sure there is no secret so we can use a copy clone
 
   $ hg -R mu phase --draft 'secret()'
 
   $ hg clone -U mu Tau
