Some CPUs advertise RDRAND in CPUID, but return
0xFFFFFFFF unconditionally.  To avoid locking up
later, test RDRAND during initialization, and if
it returns 0xFFFFFFFF, mark it as nonexistent.

Also fix a possible segmentation fault in CPUID check.

When building the project using cmake then installing it.  The
definitions in `json_object_iterator.h` are required but not installed
by the cmake install rule.  This patch adds the `json_object_iterator.h`
file to the list of files to install.

Avoid uninitialized variable warnings

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_private: Use unsigned 32-bit integer type for refcount

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

This is recommended by the libtool manual.

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

json_object: Add const size_t json_c_object_sizeof()

Makefile: Add ACLOCAL_AMFLAGS

Fix non-GNUC define for JSON_C_CONST_FUNCTION

This is recommended by the libtool manual.
