This adds various new macros (_SAFE variants in particular) for queue operations. Consequence is removal of CIRCLEQs which were removed in FreeBSD (and later in other BSDs) in 2000 (sic!), original commit citation: "CIRCLEQs are a disgrace to everything Knuth taught us in Volume 1 Chapter 2. Retire them before anybody starts to use them again. Use TAILQ instead, it provides the same functionality."
