evolve: add a `--stop` flag for `hg evolve` command
This patch adds a `--stop` flag for `hg evolve` command. The stop flag lets you
stop the evolution from where you are and let you move to other things if you
want. This fuctionality is great as user can decide to resolve conflicts later
on, stop the command execution, do something else and get back once they has
time or care about resolving them.
As implementation details, it clears the evolvestate, updates to the parent of
working directory clearing the uncommitted changes which also deletes the
mergestate.
A new test file test-evolve-stop.t is added with tests of the new flag added.
====================================
Testing head checking code: Case C-1
====================================
Mercurial checks for the introduction of multiple heads on push. Evolution
comes into play to detect if existing heads on the server are being replaced by
some of the new heads we push.
This test file 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
