Support Get and Set access for memory mappings

Mapping memory handles to virtual memory addresses do not make them
accessible. The set access function is needed to make the memory
mappings accessible to specific agents. The get access function
returns current access properties for individual agents.

This is part of patch series for Virtual Memory API.
