[PATCH 05/14] qemu: Move feature filtering to qemuMonitorJSONGetCPUProperties

[Jiri Denemark via Devel <devel@xxxxxxxxxxxxxxxxx>]

From: Jiri Denemark <jdenemar@xxxxxxxxxx>

When getting enabled CPU features (qemuMonitorJSONGetCPUData), we used
to call qemuMonitorJSONGetCPUProperties to get the list of all boolean
properties and then queried their values and ignored properties that
were not true. By moving the filtering inside
qemuMonitorJSONGetCPUProperties we don't need to even add disabled
features to any list and also get ready for better QMP interface.
