creating new circular-json safe stringify and replacing one call

• If there is an unknown bug in the source, this limits the exposure (and no other crashes have yet been reported)
• A follow-up PR should eliminate all unprotected references to JSON.stringify

This looks great! Thanks for the unit tests, and for adding the ASF headers. I'm fine with changing other calls in a later PR.
