LIST: [PATCH v3 2/2] rust: time: Implement basic arithmetic operations for Delta
While rvkms is only going to be using a few of these, since Deltas are
basically the same as i64 it's easy enough to just implement all of the
basic arithmetic operations for Delta types.
Keep in mind there's one quirk here - the kernel has no support for
i64 % i64 on 32 bit platforms, the closest we have is i64 % i32 through
div_s64_rem(). So, instead of implementing ops::Rem or ops::RemAssign we
simply provide Delta::rem_nanos().
