  Log:
  DragonFly's malloc only guarentees X alignment when X is a power of 2,
  otherwise we would have to use contigalloc, which is nasty.
  
  Use malloc and adjust the allocation request from a multiple of 512 to the
  nearest power of 2 greater or equal to 512 and greater or equal to the
  request size.
  
  Once a filesystem is mounted I/O operates on 512 byte boundaries anyway, so
  this bug fix only effects programs that operates directly on the block device
  such as 'newfs' and 'fsck'.
