json: reject trailing garbage
Yajl 2 has a nice feature that it can be configured whether to allow multiple JSON objects parsed from a single stream, defaulting to off. And yajl 1.0.12 at least provided a way to tell if all input bytes were parsed, or if trailing bytes remained after a valid JSON object was parsed. But we target RHEL 6 yajl 1.0.7, which has neither of these. So fake it by always parsing '[...]' instead, so that trailing garbage either trips up the array parse, or is easily detected when unwrapping the result. * src/util/virjson.c (virJSONValueFromString): With older json, wrap text to avoid trailing garbage. * tests/jsontest.c (mymain): Add tests for this.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
