This adds a new `mark` command that can be used to mark packages as either explicitly or implicitly installed. Apart from fixing the package database after installing a dependency manually, it can be used to implement upgrade workflows as outlined in #13385. The following commands demonstrate how the `mark` and `gc` commands can be used to only keep the current version of a package installed: ```console $ spack install pkgA $ spack install pkgB $ git pull # Imagine new versions for pkgA and/or pkgB are introduced $ spack mark -i -a $ spack install pkgA $ spack install pkgB $ spack gc ``` If there is no new version for a package, `install` will simply mark it as explicitly installed and `gc` will not remove it.
