Many files:
  bmove.c (ext2fs_move_blocks): New function which takes a bitmap of
  	blocks which need to be moved, and moves those blocks to another
  	location in the filesystem.
  rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a bitmap,
  	make sure all of the new parts of the bitmap are zero.
  bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap wasn't
  	being returned to the caller.
  alloc_tables.c (ext2fs_allocate_group_table): Add new function
  	ext2fs_allocate_group_table() which sets the group tables for a
  	particular block group.  The relevant code was factored out of
  	ext2fs_allocate_tables().
  dblist.c (make_dblist): Adjust the initial size of the directory block
  	list to be a bit more realize (ten plus twice the number of
  	directories in the filesystem).
  Check in interim work.
