Patches 1-4 are minor cleanups, patch 5 is the actual one that I want out
of the way before continuing down my rabbit hole of the week.
Tim Wiederhake (5):
domain_conf: Reduce scope of tmp in virDomainFeaturesDefParse
domain_conf: Reduce scope of gic_version in virDomainFeaturesDefParse
domain_conf: Reduce scope of node in virDomainFeaturesDefParse
domain_conf: Add missing break in switch
domain_conf: Fix check for hyperv stimer

Variables using `g_autofree` should not be manually VIR_FREE'd and reused.

New subject: [libvirt PATCH 5/5] domain_conf: Fix check for hyperv stimer
VIR_DOMAIN_HYPERV_STIMER happens to have the same numerical value as
VIR_DOMAIN_FEATURE_HYPERV, resulting in the if-block to always being
executed when a "<hyperv>" tag is found, whether or not it actually
contained a "<stimer>" tag. This had no ill effects, as virXPathNodeSet()
would simply return 0 if that tag does not exist.
