lib: Add minimal JSON library

lpereira · Anas Nashif · commit 04f142c4b516 · 2017-03-02T02:58:35.000Z
This is a minimal JSON parser (and string encoder helper).  This has
been originally written for the NATS client sample project, but since
it's a generic bit of code, it's also being provided as a library
outside the NATS application source.

It's limited (no support for arrays, nested objects, only integer
numbers, etc), but it is sufficient for the NATS protocol to work.
