MultiGadgetRepo is a wrapper around two or more GadgetRepos so that
they can be used at the same, facilitating migration from one repo to
another.
If a gadget appears in both repos, the definition in the first repo
takes precedence, and a warning is shown on Special:Gadgets.
This can be enabled to wrap GadgetDefinitionNamespaceRepo and
MediaWikiGadgetsDefinitionRepo by setting $wgGadgetsRepo to
'json+definition'. In this configuration, once a new JSON definition
exists for the same name, it is used instead of the old one, and the
old one can then safely be removed at a later time in the safe
knowledge that it is no longer used.

== What ==
* Remove the empty Gadget and Gadget_definition namespaces.
* Remove the "gadgets-definition-edit" user right.
* Remove need for custom namespace permissions that previously
had to extend editsitejs to apply to NS_GADGET.
== Why ==
Simplify the (unused) "GadgetDefinitionNamespaceRepo" backend for
Gadgets 2.0 by making it less radically different from the status quo.
The experimental 2.0 branch will now make use of the "gadget definition"
content model via "MediaWiki:Gadgets/<id>.json" pages, instead of
through a dedicated namespace.
When I first worked the Gadgets 2.0 branch, content models
were not a thing in MediaWiki, and interface-admin wasn't a thing yet
either. Now that we have per-page permissions and per-page content
models, we don't really need a separate namespace.
This follows the principle of least surprise, and fits well with other
interface admin and site configuration tools such as:
- Citoid, MediaWiki:Citoid-template-type-map.json,
- VisualEditor, MediaWiki:Visualeditor-template-tools-definition.json,
- AbuseFilter, MediaWiki:BlockedExternalDomains.json,
- the upcoming "Community Config" initiative.
If/when we develop the SpecialPage GUI for editing gadget definitions,
this can save its data to these pages the same as it would in
any other namespace. Similar to how Special:BlockedExternalDomains
operates on MediaWiki:BlockedExternalDomains.json.
See also bf1d6b3e93 (I6ffd5e9467), which recently removed the
gadgets-edit user right in favour of the editsite{css,js,json} rights.
