Bug#507849: lintian.d.o: group packages by source version

[Russ Allbery <rra@debian.org>]

Package: lintian
Version: 2.1.0
Severity: minor

This is a bug report corresponding to Bastian Blank's recent mail to the
mailing list.

Currently, lintian.d.o groups packages by source package name and binary
package version, which is not correct for packages where the binary package
version may be unrelated to the source package version.
linux-modules-extra-2.6 has this problem.  The packages should instead
be grouped by source package and version.

To do this, we'll need to change the format of the binary package list
to add an additional field, source package version.  In unpack/list-binpkg,
we'll need to parse the Source field out of the Packages file.  If it's
not present, we can assume it matches the binary package, including in
version.  If it doesn't contain a version, we can assume the version
matches.  Otherwise, we'll need to parse it for the version of the source
package.

Then, the reporting harness will need to be updated to use the new source
version field for package display.
