The failure path taken in the event of printbuf_new() returning NULL
calls free() on tok->stack after already having freed tok. Swap the
order of the two calls to fix an obvious memory access violation.

`struct lh_string` really needs to be renamed and moved to json_object.h

The allocation of printbuf_new might fail. Return NULL to indicate tis
error to the caller. Otherwise later usage of the returned tokener would
lead to null pointer dereference.

This causes previously failing strings like "123-456" to return a valid json_object with the appropriate value.  If you care about the trailing content, call json_tokener_parse_ex() and check the parse end point with json_tokener_get_parse_end().

Deprecate the json_parse_double() function from json_util.h

While here, drop the utf8_replacement_char that is unnecesarily added if we run out of input in the middle of a unicode escape.  No other functional changes (yet).

fix issue 616: support the surrogate pair in split file.

Also add the json_object_new_array_ext, array_list_new2, and array_list_shrink functions.

Fix compiler errors and warnings when building on IBM operating systems such as AIX and IBM i.

The second call to newlocale() with LC_TIME accidentally made things
 work because LC_TIME == LC_NUMERIC_MASK on some platforms.

Add several additional test cases for partial parsing of infinity values.

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.

This reverts commit aaba8c1080.

This commit breaks builddir != srcdir build, but, more importantly, it
also adds a dependency on a header, "config.h", which is not installed
and it's supposed to be private — since it's generated at configuration
time and it's not meant to be used by projects compiling against a
library.

Also undo NULL check in json_tokener_set_flags(): it's not at all valid toi
 try to set flags on a NULL pointer, and doing so should not be silently
 ignored.
