c5a09a32a9 fuzzing: Fuzz different print methods
This is achieved by encoding the type of function used in the first two
bytes.

First byte:
b: buffered

Second byte:
f: formatted

4785070ad3 fuzzing: Fuzz printing as well.
With one big limitation: It can only be fuzzed with what has been
parsed by the library beforehand.

331c18d09a ensure: only memcopy what's necessary
We don't need to copy the entire printbuffer, only the part that is
used.

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

9f6fa94c91 ensure: replace pow2gt with multiplication by two
This replaces the bit fiddling involved with calculating a new buffer
size by just multiplying the required length by two, paving the way to a
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.

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.
