[libvirt] [glib PATCH 01/15] po: provide custom make rules for po file management

Historically we have relied on intltool to install a standard po/Makefile.in.in which has very limited scope for customization. intltool is deprecated in favour of standard gettextize tools, but these share the same disadvantages. Writing make rules for po file management is no more difficult than any other rules libvirt-glib has, so stop using intltool and don't use gettextize ether. Signed-off-by: Daniel P.
