Bill Currie 76ac446156 [util] Fix an out-by-one in QF_bsearch_r
And rename _bsearch to QF_bsearch_r since that's far less confusing.
Also, update the test to make it possible for valgrind to detect the
out-by-one. The problem was found when trying to remove components from
an entity when using subpools.
