ChangeLog, e2fsck.8.in, e2fsck.h, pass3.c, pass4.c, super.c:
  e2fsck.h: Add new field, priv_data to the e2fsck context structure.
  	It should be used by callers of the e2fsck functions only, and not by
  	anything in e2fsck itself.
  super.c: Instead of call ext2fs_get_device_size(), define and call
  	e2fsck_get_device_size().  (This function may be stubbed out in
  	special versions of e2fsck.)
  pass3.c, pass4.c: Remove extra calls to the progress function that
  	weren't needed.
  mke2fs.8.in: Update man page to note that the format of the bad block
  	file is the same as the one generated by badblocks.
