[libvirt] [PATCH] enable format-safety checks for virDomainReportError

[Jim Meyering]

This enables format-safety checks for virDomainReportError,
so that if you try to print e.g., an int via "%s", gcc will
detect it.  The Makefile.maint check ensures that all string
arguments to virDomainReportError are marked for translation
with _(...).

Subject: [PATCH] enable format-safety checks for virDomainReportError

* src/domain_conf.c (virDomainReportError): Declare using
ATTRIBUTE_FORMAT(printf, 3, 4).
* Makefile.maint (msg_gen_function): Add virDomainReportError.
