    Added a reader/writer locking mechanism to allow multiple
    concurrent namespace walks (readers), but a dynamic table unload
    will have exclusive access to the namespace. This fixes a problem
    where a table unload could delete the portion of the namespace that
    is currently being examined by a walk. Adds a new file, utlock.c
    that implements the reader/writer lock mechanism. ACPICA BZ 749.
