morestatus: move fb extension to core by plugging to `hg status --verbose`

morestatus extension in fbext use to show more context about the state of the
repo like the repository is in a unfinished merge state, or a rebase is going
on, or histedit is going on, listing the files which need to be resolved and
also suggesting ways to handle the situation.

This patch moves the extension directly to core by plugging it into the
--verbose flag of the status command. So now if you are in any unfinished state
and you do hg status -v, it will show you details and help related to the state.

The extension in fbext also shows context about unfinished update state
which is not ported to core as that plug in hooks to update command which need
to be tackled somewhat differently.

The following configuration will turn the behaviour on by default

[commands]
status.verbose = 1

You can also skip considering some states like bisect as follows:

[commands]
status.skipstates=bisect

This patch also adds test for the feature.

.. feature::

   ``hg status -v`` can now show unfinished state. For example, when in
   an unfinished rebase state, ``hg status -v`` might show::

   # The repository is in an unfinished *rebase* state.
   # No unresolved merge conflicts.
   # To continue:                hg rebase --continue
   # To abort:                   hg rebase --abort
