Add more information about Bluetooth usage.
The patch shows how to create a remote device connection and how to manage devices in /etc/bluetooth/hosts. The multimedia chapter was extended with a description on how to set up and connect a Bluetooth audio device as a sound sink. It also adds man page references to man-refs.ent for hcsecd(8) and virtual_oss(8), respectively. I cleaned up the patch a bit for consistency and proper markup.
