- Fix DEVICE_NODE definition to remove ROS-only fields

- Move RTL_HEAP_PARAMETERS to umtypes.h
- Fix PROCESS_PRIORITY_CLASS_XXX definitions.
- Use PROCESS_PRIORITY_CLASS_INVALID in process creation code.
- Move and correct EX_PUSH_LOCK definition to ntifs.h
- Define KQUEUE along with KAPC_STATE if ntifs.h is not used, so that we don't force its usage
- Enable usage of EX_QUEUE_WORKER_INFO and EX_WORK_QUEUE without requiring the IFS.
- Fix definition of CsrClientConnectToServer
- Update NDK FIXME list
- Define and use a list of Bus Type GUIDs instead of saving the GUID in a ROS-only field of DEVICE_NODE.
- Use a IRP_MN_QUERY_CAPABILITIES PnP IRP to get the Address of a DeviceNode, intead of saving it inside a ROS-only field.
