Add RCU-enabled variants on the existing bsd DQ facility. Each
operation has the same interface as the existing (non-RCU)
version. Also, each operation is implemented as macro.
Using the RCU-enabled QLIST, existing QLIST users will be able to
convert to RCU without using a different list interface.
