Bluetooth: Implement link key handling for the management interface
This patch adds a management commands to feed the kernel with all stored link keys as well as remove specific ones or all of them. Once the load_keys command has been called the kernel takes over link key replies. A new_key event is also added to inform userspace of newly created link keys that should be stored permanently.
