There are a few cases where an error returned by `nghttp2` could
have been silently ignored. Thanks to ilhamaf for reporting this!
As far as I can tell there is no actual impact, except perhaps that
we can detect errors/stale connections earlier, but I haven't been
able to cause any actual problem introduced by not handling these

dnsdist: Handle missing X-Forwarded-For on existing DoH connection

If `trustForwardedForHeader` is enabled, meaning we trust an upstream
reverse-proxy to fill it with the address of the initial client, and
the header was set on at least one previous query of the current DoH
connection, but is missing from the current query, we should fall back
to the address the connection is coming from instead of using the value
of the last received `X-Forwarded-For` header.
This should never happen in practice: if we trust the reverse proxy
to set the `X-Forwarded-For` header it should always do so. But let's
handle the case nevertheless, or we will get an endless stream of
reports from LLMs about it.
