Changes from v1:
* Reworded the help message and the docs telling the user that the fs will be
  resized to it's max size (suggested by Wenruo)
* Added a warning message saying that the resize failed, asking the user to
  resize manually. (suggested by Wenruo)

Both changes were done only in patch 0002.

Anand suggested this job to be done in kernel side, atomically, but as I
received a good review from Wenruo I decided to send a v2 of this patchset.

Please review, thanks!

Original cover-letter[1]:
These two patches make possible to resize the fs after a successful replace
finishes. The flag -a is responsible for doing it (-r is already use, so -a in
this context means "automatically").

The first patch just moves the resize rationale to utils.c and the second patch
adds the flag an calls resize if -a is informed replace finishes successfully.

Please review!
