This script is intended to help in synchronizing i386 QEMU cpu
feature definitions with libvirt.
QEMU's attribute list for the "max-x86_64-cpu" contains non-cpu-feature
items and needs to be filtered before being useful.

cpu-data.py assumes that all "feature" nodes have exactly one child.
This assumption will no longer be true when the cpumap includes alias-

virNWFilterDHCPSnoopShutdown would never destroy the mutexes created
in virNWFilterDHCPSnoopInit. Additionally, if in virNWFilterDHCPSnoopInit
the call to virMutexInitRecursive succeeds and the call to virMutexInit
fails, this would lead to either virNWFilterSnoopState.snoopLock being
initialized twice or virNWFilterSnoopState.activeLock destroyed without
being initialized first.
This enables a later patch to use virNWFilterDHCPSnoopShutdown as a
cleanup function safely, as it is a no-op if virNWFilterSnoopState was
not yet initialized.
