bundle2: no longer use 'retractboundary' in updatephases
The new 'phase-heads' forced all added node to secret before advancing the
boundary to work around the fact changesets were added as draft by default.
This is no longer necessary since the changegroup part can now use the
'targetphase' parameter.
Not doing this retract boundary call has a couple of advantages:
* This makes implementing phases change tracking in the transaction much
simpler since retract boundary can become a rare case.
* Bundling secret changesets is not the norm. Exchange never does that and
even for strip, the use-case is not common.Skipping the retract boundary
will avoid useless work here.
* Sending phase update on push can be simplified since we can rely on the
behavior of 'cg.apply' for most of it.
This means less phases update send for example.
* We no longer needs to track and use the addednodes during unbundling. This
make it possible to have multiple 'changegroup' and 'phase-heads' parts in the
same bundle without them interfering with each others.
The new part has not been part of any release yet so we do not offer backward
compatibility yet. It is important to update this semantic before the 4.3
freeze happens.

==================================== Testing head checking code: Case D-6 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category D: remote head is "obs-affected" locally, but result is not part of the push TestCase 6: single changeset, superseeded then pruned (on a new changeset unpushed) changeset This is a partial push variation of case B-6 .. old-state: .. .. * 1 changeset branch .. .. new-state: .. .. * old branch is rewritten onto another one, .. * the new version is then pruned. .. .. expected-result: .. .. * push denied .. .. graph-summary: .. ..
