------------------------------+--------------------------------
 The key/value format K=V is used extensively in the Tor code and seems
 many places uses their own way to parse that.

 This ticket is for implementing a library to parse such K/V construction.
 There is a world where we might require V to be quoted or not so I'll let
 this challenge to the implementer(s).

 This ticket comes from the work done in #28179 that implements messages
 from the PT to the Tor process.
