WGLC: Mid-stream trailers

However, multiple trailer sections interleaved with content have only been deployed as frame extensions.

Trailers that come after the body has well-defined semantics (i.e. metadata applicable to the entire body).

Interleaved, mid-stream trailers are considered and implemented as extensions, and maybe we should delay adding them to the core semantics.

This is however an important topic for HTTPAPI, IMO.

Discussed at Feb 21 interim; sentiment is to remove it; @royfielding to create a PR.
