nilfs2: add ioctl which limits range of segment to be allocated
This adds a new ioctl command which limits range of segment to be
allocated. This is intended to gather data whithin a range of the
partition before shrinking the filesystem, or to control new log
location for some purpose.
If a range is specified by the ioctl, segment allocator of nilfs tries
to allocate new segments from the range unless no free segments are
available there.
