Correct BD_ADDR entry for "Dummy" device in the default hcsecd.conf.
Each byte in BD_ADDR should exactly two nibbles, i.e
"1:2:3:4:5:6" is NOT valid and "01:02:03:04:05:06" is valid BD_ADDR.

Start integrating Bluetooth into rc.d system.

Introduce /etc/rc.d/bluetooth script to start/stop Bluetooth devices. It
will be called from devd(8) in response to device arrival/departure events.
It is also possible to call it by hand to start/stop particular device
without unplugging it.

Introduce generic way to set configuration parameters for Bluetooth devices.
By default /etc/rc.d/bluetooth script has hardwired defaults compatible
with old rc.bluetooth from /usr/share/netgraph/bluetooth/examples. These
can be overridden using /etc/defaults/bluetooth.device.conf file (system
wide defaults). Finally, there could be another device specific override
file located in /etc/bluetooth/$device.conf (where $device is ubt0, btccc0
etc.)

The list of configuration parameters and their meaning described in the
/etc/defaults/bluetooth.device.conf file. Even though Bluetooth device
configuration files are not shell scripts, they must follow basic sh(1) syntax.

The bluetooth.device.conf(5) and handbook update will follow shortly.
