Kernel/IPC: Use Ports and Sessions as the fundamental building block of Inter Process Communication.
All handles obtained via srv::GetServiceHandle or svcConnectToPort are references to ClientSessions. Service modules will wait on the counterpart of those ClientSessions (Called ServerSessions) using svcReplyAndReceive or svcWaitSynchronization[1|N], and will be awoken when a SyncRequest is performed. HLE Interfaces are now ClientPorts which override the HandleSyncRequest virtual member function to perform command handling immediately.

* buffer and emulate the call accordingly. Since the code can directly read the emulated memory,
