BusyBox has no business hard coding the number of major and minor bits for a
dev_t. This is especially important now that the user space concept of a dev_t
and the kernel concept of a dev_t are divergant. The only bit of user space
allowed to know the number of major and minor bits is include/sys/sysmacros.h
(i.e. part of libc). When used with a current C library and a 2.6.x kernel,
this fix should allow BusyBox to support wide device major/minor numbers.
