fix: add extra field to fixed revisions to avoid creating obsolescence cycles
The extra field prevents sequential invocations of fix from producing the same
hash twice. Previously, this could cause problems because it would create an
obsolescence cycle instead of the expected new successor.
This change also adds an explicit check for whether a new revision should be
committed. Until now, the code relied on memctx.commit() to quietly do nothing
if the node already exists. Because of the new extra field, this no longer
covers the case where we don't want to replace an unchanged node.

==================================== Testing head checking code: Case C-2 ==================================== 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 C: checking case were the branch is only partially obsoleted. TestCase 1: 2 changeset branch, only the head is rewritten .. old-state: .. .. * 2 changeset branch .. .. new-state: .. .. * 1 new changesets branches superceeding only the head of the old one .. * base of the old branch is still alive .. .. expected-result: .. .. * push denied .. .. graph-summary: .. ..
