split: drop the experimental flag I've been using it without issue for some time. The only blocker in my mind was the lack of commit message preservation and this is now fixed.

split: preserve original changesets description Losing the description on split is to much an issue, we offer the original description to edition for every part of the split.

merge with stable

readme: updateing changelog We forgot a couple of recent improvement.

evolve: rewrite command help (evolve command only)

parents: avoid locking the repository during 'hg parents' The wrapping code was initially written for update and pull who need the lock anyway. We duplicated the logic in the parent case to remove the need for locking.

README: update instructions for running tests.

tests: remove the custom run-tests.py This test-runners is a copy from the Mercurial one and slowly drift out of sync. Use the Mercurial's core test runners instead.

make: clean test related target We removed the runner, so they are broken. We can reintroduce them later with proper data to fetch an official 'run-tests.py' runner.

test: use 'dummyssh' from the run-tests directory This is a step toward not shipping our own test runners and relying on the official Mercurial one.

test: use 'killdaemons.py' from the run-tests directory This is a step toward not shipping our own test runners and relying on the official Mercurial one.

merge back with stable

merge with default there is some 3.6 related fix and test change that we need on default. No other significant change happened since last release expect for split, still marked experimental. So we prepare for a bugfix release.
