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

Add an optional way to use an incremental chunk size ($TEST_PARSE_CHUNKSIZE)
for all of the single_basic_parse tests, in additional to the regular way.

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.

Json object split

Issue #508: `-fPIC` to link libjson-c.a with libs

json-c has symbol collisions with other popular C JSON libraries.
To prevent random crashes in downstream applications that may use a
library which depends on json-c, the solution is to statically link
libjson-c.a into those libraries.

`-fPIC`/`-fPIE` is required when building a `.a` so it can be linked
into a `.so`.

Remove all of the temporary defines, structures, old compat fuctions, extra fields, etc... that were needed during the conversion to a split set of json_object_* structures.

The default is now that string data is stored inline at the end of json_object, though to allow for json_object_set_string() to set a _longer_ string, we still need to allow for the possibility of a separate char * pointer.
All json types have been split out now, next step it cleanup.

get_cryptgenrandom_seed: compat with old windows + fallback

Clean up the code in json_object_new_* a bit by dropping unnecesary json_object_base variables.

The current changes split out _only_ json_type_object, and thus have a number of hacks
 to allow the code to continue to build and work.

Originally  mentioned in issue #535.
When complete, this will probably invalidate #552.
This is likely to cause notable conflicts in any other significant un-merged
changes, such as PR#620.
