[libvirt] [PATCHv2 06/11] qemu_monitor: Introduce qemuMonitorCPUModelInfoRemovePropByBoolValue

[Chris Venteicher]

Filter out cpu properties in qemuMonitorCPUModelInfo structure based on
boolean value of true or false.

Goal is to form a list of "enabled" or "disabled" properties.

Required to convert between cpu model feature / property lists that
indicate if property is or isn't include in model and the form of cpu
model feature / property lists that only enumerate properties that are
actually included in the model.
