Usually RFC documents are not modified, but the vast mentions of
"zenith" in early RFC documents make it desirable to update the product
name to today's name, to avoid confusion.
## Problem
Early RFC documents use the old "zenith" product name a lot, which is
not something everyone is aware of after the product was renamed.
## Summary of changes
Replace occurrences of "zenith" with "neon".
Images are excluded.
