Thanks for removing the PERF_NAVIGATION constant. I just checked with
Zhiheng and there are no pending spec updates. Also, based on the
stats for HTTP authentication, as we agreed upon, we will not cover
that case in the current version.

So I think we are on track to move to PR once Karen confirms AI 68 is done.

Initially, entryTypes were shorts and required integer constants. We later changed most constants to strings, but it appears this one was missed.
