[libvirt] [PATCH v5 04/12] target-i386: Register aliases for feature names with underscores

Registering the actual names containing underscores as aliases will allow management software to be aware that the old compatibility names are suported, and will make feat2prop() calls unnecessary when using feature names. Also, this will help us avoid making the code support underscores on feature names that never had them in the first place. e.g. "+tsc_deadline" was never supported and doesn't need to be translated to "+tsc-deadline". In other word: this will require less magic translation of strings, and simple 1:1 match between the config options and actual QOM properties. Note that the underscores are still present in the FeatureWordInfo::feat_names arrays, because add_flagname_to_bitmaps() needs them to be kept. The next patches will remove add_flagname_to_bitmaps() and will allow us to finally remove the aliases from feat_names.
