add bsearch for arrays

Remove trailing whitespaces

improve doc for json_object_to_json_string()

Arrays can already be sorted with json_object_array_sort() which uses
qsort() of the standard C library. This adds a counterpart using the
bsearch() from C.

* CVE-2013-6371: hash collision denial of service
* CVE-2013-6370: buffer overflow if size_t is larger than int

Add json_object_free_userdata() and json_object_userdata_to_json_string() too.

Conflicts:
	json_util.c

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.

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.

As part of this create a public json_config.h with a custom define to
decide whether to include inttypes.h to avoid conflicting with other
projects config.h header.

- 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.
