libvirt/src/util/buf.h
Paolo Bonzini 649bcd72fe Add sentinel attribute for NULL terminated arg lists
* src/internal.h (ATTRIBUTE_SENTINEL): New, it's a ggc feature and
  protected as such
* src/util/buf.c (virBufferStrcat): Use it.
* src/util/ebtables.c (ebtablesAddRemoveRule): Use it.
* src/util/iptables.c (iptableAddRemoveRule: Use it.
* src/util/qparams.h (new_qparam_set, append_qparams): Use it.
* docs/apibuild.py: avoid breaking the API generator with that new
  internal keyword macro
