Require that all headers are guarded by a symbol named LIBVIRT_$FILENAME where $FILENAME is the uppercased filename, with all characters outside a-z changed into '_'. Note we do not use a leading __ because that is technically a namespace reserved for the toolchain. Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
