Ramiro Polla 38a112380b json_object: cleanup of *set_string* functions
This commit also has the side-effect that errno is set on failed calls
to json_object_set_string(_len).

Ramiro Polla 906188e1cf json_object: speed up creation of objects
Instead of using calloc(), call malloc() and initialize the relevant
fields individually.

speedup for 32-bit: ~15%
speedup for 64-bit: ~ 5%

Ramiro Polla 1f46d2f40f json_object_private: remove _delete field
This field is set based on o_type when the object is created and it is
not changed during the lifetime of the object. Therefore we can check
o_type to choose the proper delete function in json_object_put(), and
save sizeof(void *) bytes in struct json_object_private.

Ramiro Polla 5bb5e2e8fc json_object_private: save 8 bytes in struct json_object in 64-bit architectures
- there is no need for _ref_count to be uint_fast32_t (the compiler
  might decide to use a 64-bit int). make it uint32_t instead.
- reorder the 32-bit integer fields (o_type and _ref_count) so that
  there is no wasted 4-byte gap after each of them.
