Eliza Weisman 5510ba6dba trace-core: Require span IDs to be > 0 (#973) ...

This branch changes `tokio_trace_core::span::Id::from_u64` to assert
that the integer from which the span ID is constructed is greater than
zero. This is to enable future use of non-zero optimization.

Unfortunately, we can't actually use a `NonZeroU64` _now_, as that type
was only stabilized in Rust 1.28.0, and `tokio`'s current minimum
supported Rust version is 1.26.0.

Adding and documenting the assertion now allows us to change the
internal representation to `NonZeroU64` later (when 1.28.0 is the
minimum supported Rust version), without causing a breaking change.
