Initial implementation of a unified application wide static network security configuration. This currently encompases: * Trust decisions such as what trust anchors to use as well as static certificate pinning. * Policy on what to do with cleartext traffic. In order to prevent issues due to interplay of various components in an application and their potentially different security requirements configuration can be specified at a per-domain granularity in addition to application wide defaults. This change contains the internal data structures and trust management code, hooking these up in application startup will come in a future commit. Change-Id: I53ce5ba510a4221d58839e61713262a8f4c6699c
