Fixing topology related internal interface/class tree

- Moved TopologyInternal to more appropriate place

 --- BaseInternalTopology (was TopologyInternal)
  |
  +-- ImmutableInternalTopology (new)
  |
  +-- MutableInternalTopology (new)

- Updated TopologyImpl, etc. to implement appropriate
  *InternalTopology interface

- Added interface adaptor BaseTopologyAdaptor
   BaseInternalTopology (self-contained) -> BaseTopology (object handle)

- TopologyObjects ({Switch,Port,Link,Host}Impl) is now common
  between Mutable and Immutable variant of Topology.
   There were locks for whole Topology, but there weren't any locks
   per TopologyObject. If these instances were on MutableTopology,
   then locking should happen outside these instance method calls.
