* Add TraceState to API * Add tests for TraceState * Update related tests - stdout exporter test - SDK test * Update OTLP span transform * Update CHANGELOG * Change TraceState to struct instead of pointer - Adjust tests for trace API - Adjust adjacent parts of codebase (test utils, SDK etc.) * Add methods to assert equality - for type SpanContext, if SpanID, TraceID, TraceFlag and TraceState are equal - for type TraceState, if entries of both respective trace states are equal Signed-off-by: Matej Gera <matejgera@gmail.com> * Copy values for new TraceState, adjust tests * Use IsEqualWith in remaining tests instead of assertion func * Further feedback, minor improvements - Move IsEqualWith method to be only in test package - Minor improvements, typos etc. Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com>
