I noticed I was getting different results when comparing nfsdctl's config file handling versus rpc.nfsd's. First, the vers4 config option was being treated as a mask, e.g. if vers4=n and vers4.2=y then end result was still that all minorversions were disabled. Change it so that vers4=n would initially toggle off all minorversions, but individual v4.x=y would turn that minorversion back on. Second, don't make assumptions about what default should be passed to conf_get_bool. Instead, test both possible values and only update the nfsd_versions array if an option was explicitly specified. Finally, add a check so that 'nfsdctl autostart' will error out if no versions or minorversions are enabled.
