Tiny JSON parser in C that uses only fixed-extent storage.

This code parses the largest subset of JSON that can be unpacked into static C structures, without using malloc(3). It is very small and very low-footprint, intended for use in constrained embedded environments. It may also be of interest for code where malloc is verboten to reduce reliability and security vulnerabilities.
