3dsp sample app and Bluez v5

[Gary Mort <gary@mort.net>]

I am trying to convert a pair of 3D bluetooth glasses into 'Joo Janta 
200 Super-Chromatic Peril Sensitive Sunglasses'  and so it seemed a 
small modification to 3dsp to play with different frequencies would fit 
the bill.

Following the command line help, I kept getting the message
  ' Failed to open HCI user channel' and since it was an extremely tiny 
c file, I tracked that down to a failure at line 642    hci_dev = 
bt_hci_new_user_channel(index);

I noticed that there was a different method of opening a socket right 
above it,    hci_dev = bt_hci_new_raw_device(index); and it was 
controlled via a command line arguement.

So adding -r to my command line, my server now seems to execute. 
However, when I try to run 3dsp in client mode from a second terminal 
window it does not connect[as well as my actual glasses not connecting]

I figured before spending too much time on this, I'd check to see if the 
code is supposed to work at this point - in which case it is my 
system..or if the bluez api has changed sufficiently that I need to 
modify the code to use some new api?
