This is a series of 8 patches that prepares for the 64-bit block number support in e2fsprogs:
- change a few variable types to blk_t type to support 64-bit block numbers in a next step,

- introduce a new option to mkfs to build ext4 filesystems with larger group descriptor sizes,

- introduce helper functions, similar to those existing in the ext4 kernel code, to access 64-bit block counters split in two 32-bit words.

Code compiled and "make check" passed.

The patchset is composed of the following patches:
1/8 :  use existing function ext2fs_group_first_block()
    This function will be change in a next step to support 64-bit block numbers.
    This patch will allow to make the change in a single place.

2/8 : convert block number definition to blk_t

3/8 : add new -D <desc-size> option to mkfs

4/8 : add new macro to get descriptor number

5/8 : add new inline functions to get blocks counters
6/8 : change access to the filesystem blocks counter
7/8 : change access to the reserved blocks counter
8/8 : change access to the free blocks counter
