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.

treewide: use get_random_bytes() when possible The prandom_bytes() function has been a deprecated inline wrapper around get_random_bytes() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. This was done as a basic find and replace.
