ace5047782 parse_string: reduce mental burden when reading the code 
This restructures parse_string in a way, that you need to keep less
state in your head to understand the code.

This is achieved by:
* only changing the input pointer (current position) at a few places
(not all throughout)
* splitting out the UTF16 handling into a separate function
* renaming the variables so you know what they do without additional
context

complete switch to size_t at a later point in time.

3facca4792 parse functions: Only set type after successful 
This sets the type of an item only if parsing was successful.

This means that in case of failure, the item's type will remain to be
cJSON_Invalid.

Max Bruckner
94117a5d23 Fix #105, double free when parse_string fails 
This fixes a double free that happens when calling cJSON_Delete on an
item that has been used by parse_string and it failed parsing the
string.

The double free happens, because parse_string frees an alias of
item->valuestring, but doesn't set item->valuestring to NULL.

87f77274de cJSON_SetNumberValue: Fix undefined double to int conversion 
This might cause slight changes in behavior, but it shouldn't break
anything that is not already broken (for example the original macro
could either return a double, or an integer or whatever depending on if
object is NULL or not.)

e69db83de5 Temporarily disable warning when const is cast away. 
There was a long running discussion here
https://github.com/DaveGamble/cJSON/pull/80 how to provide const
correctness for users of cJSON.

To avoid breaking changes for users of cJSON v1 it was decided to
disable this warning.

pragma was tested with gcc 5.4.0/6.2.1 and clang 3.8/3.9.

Otherwise, the check is just undefined behaviour. gcc even takes out
this check because len can never be zero if len does not wrap around.
