lib: introduce initial implementation of object aggregation manager This lib tracks objects which could be of two types: 1) root object 2) nested object - with a "delta" which differentiates it from the associated root object The objects are tracked by a hashtable and reference-counted. User is responsible of implementing callbacks to create/destroy root entity related to each root object and callback to create/destroy nested object delta.

lib: objagg: implement optimization hints assembly and use hints for object creation Implement simple greedy algo to find more optimized root-delta tree for a given objagg instance. This "hints" can be used by a driver to: 1) check if the hints are better (driver's choice) than the original objagg tree. Driver does comparison of objagg stats and hints stats. 2) use the hints to create a new objagg instance which will construct the root-delta tree according to the passed hints. Currently, only a simple greedy algorithm is implemented. Basically it finds the roots according to the maximal possible user count including deltas.

lib: objagg: add root count to stats Count number of roots and add it to stats. It is handy for the library user to have this stats available as it can act upon it without counting roots itself.
