sjson: Fast and portable C single header json Encoder/Decoder

@septag

This is actually a fork of Joseph's awesome Json encoder/decoder code from his repo.
If you want to see the performance and analysis of the original encoder/decoder (which is ccan/json) visit here.
The encoder/decoder code is almost the same. What I did was adding object pools and string pages (sjson_context) that eliminates many micro memory allocations, which should improve encode/decode speed and data access performance. I also added malloc/free and libc API overrides, and made the library single header, so it makes it very easy to integrate it into other programs

Features

• Single header C-file
• UTF8 support
• Fast with minimal allocations (Internal Object pool, String pool, ..)
• Overriable libc functions like malloc/free/memcpy/..
• Supports both Json encoding and decoding
• Encoder supports prettify
• No dependencies
• Simple and easy to use C-API

Usage

#define SJSON_IMPLEMENT
#include "sjson.h"	

For more information, check out the header file itself.
