[libvirt] [PATCH 4/9] iptables.c: Use virStrerror, not strerror.

[Jim Meyering <jim@xxxxxxxxxxxx>]

From: Jim Meyering <meyering@xxxxxxxxxx>

* src/iptables.c: Include "virterror_internal.h".
Use virStrerror, not strerror.
* src/virterror.c (virStrerror): Remove "static".
* src/virterror_internal.h (virStrerror): Declare it.
