    Sync sys/queue.h with FreeBSD:
    
    * Introduce REMOVE_NEXT() macro's for SLIST and STAILQ.
    
    * Add sanity checking for QUEUE(3) TAILQs and LISTs under
    INVARIANTS.  Races may lead to list corruption, which can be
    difficult to unravel in a post-mortem analysis.  These checks verify
    that the prev and next pointers are consistent when inserting or
    removing elements, thus catching any corruption earlier.
    
    * Use TRASHIT to break LIST and SLIST link pointers on element removal.
    
    * Add more _FOREACH_MUTABLEs. Note: FreeBSD and NetBSD call these _SAFE,
    but _MUTABLE is a better name, so that's what we're using.
    
    * Add a macro for SLIST traversal 'SLIST_FOREACH_PREVPTR',
    this macro keeps a pointer to the previous element's next
    pointer to allow for search and O(1) removal.
    
    * Remove CIRCLEQs and replace them with TAILQs.
