common/memory: add check-callback to getPath() to select desired path
...
This is a workaround until we have a better heuristic (maybe shortest
path?) to choose between multiple paths in the graph. Since the (abstract)
graph has no idea about memory translations, getPath() may even yield
paths that are no valid translation because a pair of inbound/outbound
edges must not neccessarily share a common address window, but from the
perspective of the abstract graph present a valid path.
The callback function is used by the MemoryManager to verify if a path
candidate represents a valid translation.

lib/memory: rework allocators to make them extensible and more abstract

This is change renders memory allocators only dependend on an address
space id that they are managing, allowing easy implementation of other
algorithms and instantiation in memory IP blocks.
