The following patches fill out more complete media signatures for Fedora and Windows distros. With Windows distros the ISO signatures are following a complete bizarre scheme that we can't interpret and it is easy to make mistakes in the libosinfo database rules. Even the Fedora ISO signatures turn out to have subtle difference between releases. Thus this series creates a test case for checking our rules. The test case requires that the output of 'isoinfo -d -i ISOFILE' is placed under tests/isodata/$DISTRO/$SHORTID/$ISOFILENAME.txt It then validates that the rules match each set of data.
