/**
* virQEMUCapsFillDomainFeatureGICCaps:
* @qemuCaps: QEMU capabilities
* @domCaps: domain capabilities
*
* Take the information about GIC capabilities that has been obtained
* using the 'query-gic-capabilities' QMP command and stored in @qemuCaps
* and convert it to a form suitable for @domCaps.
*
* @qemuCaps contains complete information about the GIC capabilities for
* the corresponding QEMU binary, stored as custom objects; @domCaps, on
* the other hand, should only contain information about the GIC versions
* available for the specific combination of architecture, machine type
* and virtualization type. Moreover, a common format is used to store
* information about enumerations in @domCaps, so further processing is
* required.
*
* Returns: 0 on success, <0 on failure
