RFC e2fsprogs: reserve more special inodes

All reserved special inodes are used for various features (some of them never been implemented in mainline). This patchset add option for reserving more special inodes at mkfs time and option to reseze2fs for relocating first inodes in existing filesystem and reserving them for special usage.

No changes in layout are required because index of first normal inode already stored in superblock.

[ this is preparation for adding project quota feature ]
