This change introduces JSON_C_OBJECT_ADD_CONSTANT_KEY
as a replacement of JSON_C_OBJECT_KEY_IS_CONSTANT.
The description of json_object_object_add_ex tells to
look at the flags JSON_C_OBJECT_ADD_* but it is not
for JSON_C_OBJECT_KEY_IS_CONSTANT.
From the point of vue of a developper using json-c,
the function json_object_object_add_ex is mainly used,
not the hash facility, it seems more natural to provide
a regular naming of prefix JSON_C_OBJECT_ADD_CONSTANT_KEY.
2.replace json_object_get/put API with json_object_retain/release, as they operate the reference counter, and confused with array_list_get/put_idx.
3.replace array_list_get/put_idx API with array_list_get/insert to make them more clear to use.
To better distinguish between entry->k and entry->v being const within linkhash, but non-const outside, add lh_entry_v() and lh_entry_k() accessors.
Make lh_entry->k const.
These items were used for statistics tracking, but no code at all
exists to consume them. By removing them we save
a) space
because they counters required space, and did so in each and every
json object
b) performance
because calloc() needs to write less data and the counters are
no longer maintained; cache performance can be better, load
on OS main memory is lighter
We could conditionally enable/disable these counters, but I have not
done this they were really nowhere used and it looked more like a
left-over from the import of hashtable code.
This also adds a new API json_global_set_string_hash() which permits
to select the hash function. The default one is the only one that was
previously present. So there are no changes to existing apps, and the
new hash function needs to be explicitely be opted in. Especially for
smaller strings, the perllike functions seems to be around twice as
fast as the other one, with similarly good results in value distribution.
* Return value of json_object_object_add() changed from void to int.
Return value now indicates success or failure.
* Check whether allocations are successful.

* Add casts from void* to type of assignment when using malloc
* Add #ifdef __cplusplus guards to all of the headers
* Add typedefs for json_object, json_tokener, array_list, printbuf, lh_table
