* Make TraceFlags spec-compliant * Remove `trace.FlagsDebug` and `trace.FlagsDeferred` * These are used only by the B3 propagator and will be handled there in the `context.Context` * Make `trace.TraceFlags` a defined type, aliasing `byte` * Move `IsSampled` method from `trace.SpanContext` to `trace.TraceFlags` * Add `Sampled(bool)` method to `trace.TraceFlags` * Implement `Stringer` and `json.Marshaler` for `trace.TraceFlags` Signed-off-by: Anthony J Mirabella <a9@aneurysm9.com> * Rename `TraceFlags.Sampled()` to `TraceFlags.WithSampled()` for consistency * Restore `SpanContext.IsSampled()` method.
