evolve: run in a single transaction
This speeds up `hg evolve --all` of a stack of 24 commits in the hg
repo from 11.5s to 3.7s (3x). As can be seen in the tests, it also
avoid some warnings about transiently unstable commits.
==================================
Test for "orphan" type instability
==================================
This file gather test case around the "orphan" changeset instability. This
instability happens when a changesets has obsolete ancestors.

orphan parent is obsolete with a single successor
=================================================
Test orphan resolution for a changeset orphan because its parent is obsolete
with one successor.

orphan parent is obsolete with a multiple successors (reversed order)
=====================================================================
Test orphan resolution for a changeset orphan because its parent is obsolete
with multiple successors on the same branch but in reverse order (cross-split).
