* Added parameter "size_t align" to file_map_translate(). If > 1, the

vector at the end of the file will be aligned to the given value.
* BFS uses an alignment of 512 bytes (should be block size of the
  underlying device or BFS block size, whatever is less), which should
  be fine, since file data are only stored in BFS blocks. This totally
  avoids any partial operations at the I/O scheduler level, thus saving
  disk operations. Not that I could measure any performance difference.
  Theoretically it should help a lot though, particularly when dealing
  with lots of small files, since we avoid using bounce buffers, which
  are (a) limited in number and (b) require copying of the data.
