core: add per-package and per-filesystem show-info
Sometimes, it is need to quickly get the metadata of a subset of packages, without resorting to a full-blown JSON query. Introduce a new per-package (and per-filesystem) foo-show-info rule, that otputs a per-entity valid JSON blob. Note that calling it for multiple packages and.or filesystems at once will not generate a valid JSON blob, as there would be no separator between the JSON elements: $ make {foo,bar}-show-info { "foo": { foo stuff } } { "bar": { bar stuff } } However, jq is able to absorb this, with its slurping ability, which generates an array (ellipsed and manualy reformated for readability): $ make {foo,bar}-show-info |jq -s . - [ { "foo": { foo stuff } }, { "bar": { bar stuff } } ] Signed-off-by: "Yann E.
