    Remove remnants of optimization for > pagesize allocations.

    In the past, this allocator seems to have allocated things larger than
    a page seperately. Much of this code was removed at some point (perhaps
    along with sbrk() used) so remove the rest. Instead, keep allocating in
    power-of-two bins up to FIRST_BUCKET_SIZE << (NBUCKETS - 1). If we want
    something more efficent, we should use a fancier allocator.

    While here, remove some vestages of sbrk() use. Most importantly, don't
    try to page align the pagepool since it's always page aligned by mmap().
