inhibit: direct access with and without warning on a per command basis
We introduce a new filtername visibile-directaccess-nowarn to enable direct
access with no warning on a per command basis.
The motivation behing this change is to display warning when attempting direct
access in destructive commands.
inhbit: make tests work with evolution.createmarkers config
Before this patch, the test for inhibit was assuming evolve fully running.
For most of the features that inhbit enables, createmarkers is sufficient.
This patch makes the test of inhibit run with the createmarkers config and
only lifts it for operations in the middle of the stack.
