Prototype bandwidth reservation

This is a prototype of the bandwidth reservation implementation.
There is no bandwidth discovery, it is all faked.  The bandwidth is
specified by allocating a special Intent used for demonstration purposes.
This code also uses faked out interfaces in the Resource Manager, and will
need to be refactored when the real Resource Manager is in place.
