e2fsck: misc cleanups for pfsck
Add -m option description to e2fsck.8 man page.
Rename e2fsck_struct fs_num_threads to pfs_num_threads to avoid
confusion with the ext2_filsys fs_num_threads field, and move
thread_info to be together with the other HAVE_PTHREAD fields.
Move ext2_filsys fs_num_threads to fit into the __u16 "pad" field
to avoid consuming one of the few remaining __u32 reserved fields.
Fix a few print format warnings.
