This patch integrates the functionality of the former CAP session into the PD session and unifies the approch of supplementing the generic PD session with kernel-specific functionality. The latter is achieved by the new 'Native_pd' interface. The kernel-specific interface can be obtained via the Pd_session::native_pd accessor function. The kernel-specific interfaces are named Nova_native_pd, Foc_native_pd, and Linux_native_pd. The latter change allowed for to deduplication of the pd_session_component code among the various base platforms. To retain API compatibility, we keep the 'Cap_session' and 'Cap_connection' around. But those classes have become mere wrappers around the PD session interface. Issue #1841
