[Bluez-devel] [Patch] Add dbus method for obtaining RFCOMM channels

[Matthew Garrett <mjg59@srcf.ucam.org>]

So, firstly, this is something that scratches an itch I have for hal 
integration. I'm entirely open to doing it in an entirely different way 
if people would prefer that.

This patch adds a GetRFCOMMChannel dbus method, allowing channels to be 
added to hal objects. An example use case would be a phone manager - 
having the channel means that it can simply call a few dbus methods and 
then have a serial device.
