Add TunnelInterface API and KernelResourceRecords

Browse Source 
This change adds one KernelResourceRecord type (TunnelInterfaceRecord),
and adds methods for the creation of TunnelInterfaces, as well as the
application of Transforms to the given TunnelInterfaces

As part of the generation of ikeys/okeys, a ReserveKeyTracker manages a
java bitset to avoid collisions and reserve/release keys.
