Breaking changes in 2.0.0

[FSMaxB]

With 2.0.0 let's try to get things right with the following breaking changes:

• Use size_t instead of int for lengths
• Clean up the cJSON struct Clean up the cJSON struct #63
• Remove cJSON_InitHooks in favor of Need public API to free returned strings (e.g. cJSON_Print) #5
• Remove cJSON_GetErrorPtr in favor of Get rid of the global error pointer and replace it with a local one that gets passed to functions manually #59
• Maybe remove cJSON_CreateIntArray, cJSON_CreateFloatArray and cJSON_CreateDoubleArray in favor of a cJSON_CreateNumberArray macro???
• Use case sensitive string comparison cJSON_strcasecmp：converted to lower case for comparison #13
• Maybe add realloc support. (fall back to malloc if not specified available)
• Return value for cJSON_AddItemToObject and other void functions Problem with cJSON_AddItem* functions #107
• error position instead of error pointer
• Allow allocator functions that take a void * pointer with user data that get's passed through.
• cJSON_PrintPreallocated: Return size and use unsigned char*

I just found a problem with size_t: C89 doesn't specify the constant SIZE_MAX. So my little macro trick (see #27) doesn't work with size_t. I will have to rethink that. #62

@FSMaxB just to clarify:

Version 1.0.0 should be: 3a7bd69
(possibly plus a few small fixes, which I'm happy to branch out and apply).

Your new release, which requires code changes, should be 2.0.0. You're welcome to make it a separate project, but until it's tested, working, and everything is done, head MUST point to that commit.

[FSMaxB]

Understood. I will release 1.0.0 with the build system improvements ( but without the breaking changes. That includes the library version.

You are AWESOME. Thanks :)

It might be useful to return an error position instead of an error pointer. That would help to prevent pointers to invalid memory (in case the input string gets freed, but the error pointer is still around).

If a user of the library wants the old error pointer the user would just add the error position to the beginning of the json string.
