v0.9.8-r16

rTorrent 0.9.8, -jc Release 16

- allow to preallocate space for the whole torrent at once

  To enable, "system.file.allocate.set = 2".

  Currently, with system.file.allocate = 1, rTorrent preallocates space
  only after the file is opened for write.

  In many cases, it is preferable to preallocate space for the whole
  torrent at once, to reduce fragmentation of contents inside the
  torrent.

  It allows more efficient filesystem organization, where files that
  are likely to be read together are packed in contiguous area of the
  disk, improving the performance and I/O patterns of future read
  operations.
