* lint: compile cleanly under newer GCC and on 64-bit OS
 * rename SUBBLOCKSIZE to CHUNKSIZE since that is what it is
 * collect some more stats, primarily for frisbee event collection code
 * add stupid hacky bubble-sort workaround but don't define it by default
   cuz it is stupid...and hacky...but it allows mike to make an image of
   his home machine before he dies of old age
 * tweaks to libntfs version support
