base: Build caching into the AddrRangeMap class.
Rather than have each consumer of the AddrRangeMap implement caching lookups
on their own, this change adds a centralized mechanism to the AddrRangeMap
class itself.
Some benefits of this approach are that the cache handles deleted entries
correctly/automatically, the cache is maintained by adding/removing entries
from a linked list rather than moving elements in an array and checking
valid
bits, and it's easy to enable in places which might otherwise not bother
with
caching. The amount of caching is tunable to balance overhead with improved
lookup performance.
This version also fixes a bug found in the existing version and now exposed
by
the AddrRangeMap unit test.
