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.
=========================================================
Test the proper behavior of evolve during merge conflict.
