ChangeLog, main.c, resize2fs.c:
  main.c (main): Check to make sure we can really resize this
  	filesystem.  If there are compatible feature sets that we don't
  	support, we need to abort.
  resize2fs.c: Change to use the new prototype required by
  	block_iterate2 (which uses blkcnt_t for the blockcount).
version.h, RELEASE-NOTES:
  Interim commit of changes to date.
