  Modified files:
    sys/ufs/ffs          ffs_vfsops.c 
  Log:
  Pre-dirpref versions of fsck may zero out the new superblock fields
  fs_contigdirs, fs_avgfilesize and fs_avgfpdir. This could cause
  panics if these fields were zeroed while a filesystem was mounted
  read-only, and then remounted read-write.
  
  Add code to ffs_reload() which copies the fs_contigdirs pointer
  from the previous superblock, and reinitialises fs_avgf* if necessary.
