packages: Add 'package-superseded' and associated support.
This provides a way to mark a package as superseded by another one. Upgrades replace superseded packages with their replacement. * guix/packages.scm (package-superseded, deprecated-package): New procedures. * gnu/packages.scm (%find-package): Check for 'package-superseded'. * guix/scripts/package.scm (transaction-upgrade-entry)[supersede]: New procedure. Call it when 'package-superseded' is true. * tests/guix-build.sh: Add test for a superseded package. * tests/packages.scm ("package-superseded") ("transaction-upgrade-entry, superseded package"): New tests.
