Subject: [PATCH] Use reserved RCODE, fake source version
Use RCODE value assigned for a private use. Previous value were possible
returned value.
Fake source version to be still 1.7.x. Hide real version into micro
version component and export it also in a proper way with _REAL
suffixes. Should workaround any source code detection to support correct
callback format. Fixes compilation error in libreswan.
Use preprocessed unbound.h to prevent failures
Swig complains about wrong @ variable formats. Make it use preprocessed
header instead of a template.
