Hi to all,
This patch is useful for:
1) remove an unused var from extern char *find_real_root_device_name(const char* name)
changing it to extern char *find_real_root_device_name(void).
2) fixes include/libbb.h, coreutils/df.c, util-linux/mount.c and util-linux/umount.c accordingly.
3) fixes a bug, really a false positive, in find_real_root_device_name() that happens if
in the /dev directory exists a link named root (/dev/root) that should be skipped but
is not. This affects applets like df that display wrong results
