Instead of making the inclusion of the registry code a global
conditional, split the registry into two pieces; the bits required by
the X-Resource extension (the resource names) and the bits required by
the XCSECURITY extension (the protocol names). Build each set of code
if the related extension is being built.
v2: Check for both XCSECURITY and XSELINUX.
