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.
