Commit 324d4c1857 (btrfs-progs: convert: Add larger device support)
introduced new dependencies on the 64-bit API provided by e2fsprogs.
That API was introduced in v1.42 (along with bigalloc).
This patch maps the following to their equivalents in e2fsprogs < 1.42.
- ext2fs_get_block_bitmap_range2
- ext2fs_inode_data_blocks2
- ext2fs_read_ext_attr2
Since we need to detect and define EXT2_FLAG_64BITS for compatibilty
anyway, it makes sense to use that to detect the older e2fsprogs instead
of defining a new flag ourselves.
