Build fails for Varnish 5.2
Current master:
vmod_re.c:36:33: fatal error: common/common_param.h: No such file or directory
#include "common/common_param.h"
Public includes have changed for master since the 5.2 release. We'll need a 5.2 branch, and a tagged release for a VMOD version compatible with 5.2.
