Serializes a parameter object into a URL-encoded query string.
Exported because it is occasionally useful on its own; HttpRequest applies it to
Query automatically, so you rarely need to call it directly.
Rules: null and undefined entries are omitted entirely (rather than becoming the strings
"null"/"undefined"), arrays expand to repeated keys, and Date values render as ISO 8601.
