Re: [libvirt] [PATCH] util: Clean up consumers of virJSONValueArraySize

Rather than have virJSONValueArraySize return a -1 when the input is not an array and then splat an error message, let's check for an array before calling and then change the return to be a size_t instead of ssize_t. That means using the helper virJSONValueIsArray as well as using a more generic error message such as "Malformed <something> array". In some cases we can remove stack variables and when we cannot, those variables should be size_t not ssize_t. Alter a few references of if (!value) to be if (value == 0) instead as well. Some callers can already assume an array is being worked on based on the previous call, so there's less to do.
