Fix json_object_object_foreach to avoid uninitialized variable warnings
using ANSI C or MSC.

Also try to accomodate formats to explicitly exclude the decimal (e.g. %.0f).

json_object: Avoid invalid free (and thus a segfault) when ref_count gets < 0

This is recommended by the libtool manual.

json_object: Add const size_t json_c_object_sizeof()

Also, add a table of contents, and a brief section on using json-c with links to
the header files most likely to be useful.

Fix a VS 2015 compiler warning.

In VS 2015, the warning text is "warning C4550: expression evaluates to a function which is missing an argument list".

Seems to perform better than outputting to string
and re-parsing it.

BENCHMARK - 1000000 iterations of 'dst2 = json_tokener_parse(json_object_get_string(src2))' took 20 seconds
BENCHMARK - 1000000 iterations of 'dst2 = json_tokener_parse(json_object_get_string(src2))' took 7 seconds

It should make a difference on embedded systems.
The test was performed on a i5 desktop CPU [~3.5 years of age].

Because doing `json_tokener_parse(json_object_get_string(src))`
feels sloppy, dirty, and makes me want to cry at night
sometimes.
