[arch-dev-public] Update to bluez 4.1: package rename, SONAME bump and new dbus interface

So I took the time to update bluez to 4.1. The bluez-libs and bluez-utils packages have been merged into the bluez package. The SONAME has been bumped to libbluetooth.so.3 and the dbus interface is incompatible to the one in bluez 3. bluez-gnome has been ported to the new interface (didn't update that, I guess it has a maintainer). Unfortunately, the rest might not be ported to bluez 4 yet, so this will probably stay in testing for a while. Please use this thread to track any problems with this.
