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.
===============================================================================
Tests the resolution of public content divergence: when merging leads to public
===============================================================================
This file intend to cover all the cases possible when merging the other
divergent cset into public cset leads to public cset itself.
Possible variants are:
parent: same/different
relocation: [no-]conflict
merging: [no-]conflict
