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.

====================================
Testing head checking code: Case A-1
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category A: simple case involving a branch being superceeded by another.
