* each device manager node has now an autogenerated identifier
* added a generic syscall for device_manager it enables to iterate the device manager tree from userland * the listdev tool is now using it: it's still incomplete as it only dumps nodes and attributes git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19260 a95241bf-73f2-0310-859d-f6bbb57e9c96
