sscanf is always a potential problem when converting numeric
values as it does not correctly handle over- and underflow
(or at least gives no indication that it has done so).

This change converts json_object_get_double() to use strtod()
according to CERT guidelines.

Add json_object_free_userdata() and json_object_userdata_to_json_string() too.

Remove redefinition of strndup() which is no longer used in the codebase

Support NaN and Infinity

Although JSON RFC does not support NaN or Infinity
as numeric values ECMA 262 section 9.8.1 defines
how to handle these cases as strings

Conflicts:
	json_util.c

* Return value of json_object_object_add() changed from void to int.
  Return value now indicates success or failure.

* Check whether allocations are successful.

* Do not exit program from within the library.

'\f' is a llegal char and should be escape in printbuf

Adjust test_null to check for this case.

This is particularly useful when replacing values in a loop, since it allows
 the key used by json_object_object_foreach to continue to be used.

Thanks for Mateusz Loskot for the fix.

There are now three options: JSON_C_TO_STRING_SPACED, JSON_C_TO_STRING_PLAIN and JSON_C_TO_STRING_PRETTY.
This also add a json_object_to_file_ext() that takes the same flags.
Existing output of json_object_to_json_string() is unchanged, and uses JSON_C_TO_STRING_SPACED.
Thanks fo Grant Edwards for the initial patches.

that, since not all environments actually have a stdbool.h to use.

New json_object_object_get_ex() method protects itself against null pointers
and invalid objects being passed in.

In building large systems, there are often clashes over the
preferred base type to use for bool/boolean. At least one
experience has been with a 3rd party proprietary library which
can not be changed. In that case, boolean was a synonym for
unsigned char and used widely in packed structures.

VC 9 doesn't support late variable declarations, and doesn't have inttypes
so we need some direct definitions of a couple of more types.

- uses libc's qsort to sort the arraylist
 - add test in test1.c

Added parse_null test. This does not change anything with how the parser handles \u0000 or null characters

omit the range check during parsing since we already have the checks when
 accessing the value. There is no longer a json_type_int64, only json_type_int.
Fix some problems with parsing 0 and -0 values, and add a couple of tests.
Fix some minor compile issues on HPUX environments.
