Fix the code that was supposed to zero the last 16 blocks of the
volume: in the case of volumes larger than 2^32 blocks, various
conversions were conspiring to produce a range other than the intended
one.
Fix show_stats() for block numbers >= 2^32: blk_t -> blk64_t and printf
format.
Change int_log{2,10}() to take 64-bit arguments. Also change the int_log10()
implementation in progress.c in the same way.
