next: make next command --evolve by default
Before this patch, if we need to evolve to update to the next child,
we were suggesting the user to use --evolve flag. This patch make some
changes to evolve by default in that conditions.
After making next command to evolve by default we have to consider
the following points:
1) If we don't need to evolve while updating to the next child:
a) And if wdir is dirty, we suggest to use --merge flag
b) if wdir is clean, we simply update to next child (if ambiguous,
prompt the user to select one)
2) If we need to evolve:
a) when wdir is dirty, we suggest the user to use `hg shelve` first,
to make wdir clean. As we don't support --merge while evovling.
b) when wdir is clean, we evolve the next cset.
Changes made in test-prev-next.t reflect the changed behaviour.
Tests for the --abort flag for `hg evolve` command while content-divergence resolution
======================================================================================
The `--abort` flag aborts the interuppted evolve by undoing all the work which
was done during resolution i.e. stripping new changesets created, moving
bookmarks back, moving working directory back.
This test contains cases when `hg evolve` is doing content-divergence resolution.
Setup

> EOF
$ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
$ hg init abortrepo
