The implementation details of the baggage, B3 and Jaeger processing code in the OpenTelemetry.Api and OpenTelemetry.Extensions.Propagators NuGet packages can allocate excessive memory when parsing which could create a potential denial of service (DoS) in the consuming application.
BaggagePropagator.Inject<T>() does not enforce the length limit of 8192 characters if the injected baggage contains only one item.
This change was introduced by #1048.
The following methods eagerly allocate intermediate arrays before applying size limits.
