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.
This commit is a squashed and slightly modified backport
of the following commits on the master branch:
* 0e5bbcaa16
* 4d36b0287d
* 8086314026
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.
If we want to override `strerror()` in libjson-c
to make tests consistent across platforms, we
need to do it build-wide as configure/build
option.
Apple linkers make it really hard to override functions
at link-time, and this seems to be locked down on travis-ci.org
[ for security reasons I assume ].
While I got it to work locally, it did not work
when running on travis.
