Split ManagerDefault into Manager and ManagerDefinitions
This patch splits the managerdefault into a manager and a manager
defintion library that contains all pillar elements of a policy manager.
It renames the file with the name of the main class they contains.
It splits the AudioPort into AudioPort and AudioPatch.
