200fdbd361 [#149] metabase: Do not write virtual objects to the primary index
In the previous implementation of the metabase, it was necessary to write
virtual objects to the primary index to be able to select them. In this
approach, virtual objects can be obtained directly using Head operation.
This has a side effect in handling object operations that do not expect to
receive a virtual object header in a single operation. With recent changes,
it is no longer necessary to have records of virtual objects in the primary
index, so this no longer happens for system integrity.

1db01725c9 [#131] metabase: Implement indexing by object properties
Process parent objects in Put method. Headers of parent object are stored as
regular leaf objects in metabase from now. Build indexes for ROOT, LEAF and
CHILDFREE properties.
