base, mem: Disambiguate if an addr range is contained or overlaps

We need to determined whether an address range is fully contained or
it overlaps with an address range in the address range in the mmap. As
an example, we use address range maps to associate ports to address
ranges and we determine which port we will forward the request based
on which address range contains the addresses accessed by the
request. We also need to make sure that when we add a new port to the
address range map, its address range does not overlap with any of the
existing ports.

This patch splits the function find() into two functions contains()
and intersects() to implement this distinct functionality. It also
changes the xbar and the physical memory to use the right function.
