[Zope-CMF] Accessing workflow variables

[Florent Guillaume]

In DCWorkflow in general, here.portal_workflow.getInfoFor(here,'locked')
is the correct way to access a workflow variable.

However in CPS 2.0, the 'locked' variable is a stray one, it's not used.
In CPS to know if an object is locked, call here.is_locked(). There is
also is_archive, is_draft, is_stable, is_checkin_allowed,
is_checkout_allowed that you can call.

We don't use workflow variables for that for various reasons, one of
them being speed.

If you want to lock or unlock an object by hand, you have to call
become_locked or become_stable, but these are not available from
restricted code.

The only available functions from restricted code are check_in,
check_out and abandont_draft.
