Subject: [PATCH 1/2 bigalloc] e2fsprogs: change "blocks" to "clusters" in dumpe2fs

From: Robin Dong <sanbai@...bao.com>

When using dumpe2fs to display group detail of a bigalloc-fs, it displays like:

Group 413: (Blocks 54132737-54263808)
Block bitmap at 54132737 (+0), Inode bitmap at 54132738 (+1)
Inode table at 54132739-54133761 (+2)
8127 free blocks, 8184 free inodes, 0 directories
Free blocks: 54133776-54263792
Free inodes: 3379993-3388176

The "8127 free blocks" should be "8127 free clusters".

This patch is based on "next" branch of e2fsprogs.
