This branch allows users of `tokio-trace` to explicitly set a span's parent, or indicate that a span should be a new root of its own trace tree. A `parent: ` key has been added to the `span!` macros. When a span is provided, that span will be set as the parent, while `parent: None` will result in a new root span. No `parent:` key results in the current behaviour. A new type, `span::Attributes`, was added to `tokio-trace-core` to act as an arguments struct for the `Subscriber::new_span` method. This will allow future fields to be added without causing breaking API changes. The `Attributes` struct currently contains the new span's metadata, `ValueSet`, and parent. Finally, the `span::Span` type in `-core` was renamed to `span::Id`, for consistency with `tokio-trace` and to differentiate it from `span::Attributes`. This name was chosen primarily due to precedent in other tracing systems. Closes #920 Signed-off-by: Eliza Weisman <eliza@buoyant.io>
