== 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.

gadgets-edit user right in favour of the editsite{css,js,json} rights.

With GadgetDefinitionNamespaceRepo, there should be separate rights for
editing gadget json as opposed to editing gadget css/js, so that admins
can be granted the former, while the latter remains restricted to
int-admins.
Reusing the MW core rights for site CSS/JS/JSON seems to make the most
sense here. Protection is now applied via GetUserPermissionsErrors hook
rather than as namespace protection.
For editing any non-CSS/JS/JSON pages in the namespace, editsitejs right
is required.

… e.g. using modern syntax, or avoiding unnecessarily complex
language features. For example, we don't need to call count() when
all we care about is the boolean "is empty/not empty" information.

* A fixed license header for the file.
* Move class descriptions, doc tags, author/copyright to the
class block. Remove MW-core specific "ingroup" tags such as
"SpecialPage" which has no meaning in an extension and are not
used by Doxygen.

The ResourceLoader module associated with the gadget will have
mobile and desktop targets, but this allows gadgets to disable
themselves on the mobile site if necessary by not adding the gadget
to the page if it's been marked as such.
This also has the benefit of not showing the gadget on the preferences
page if it's not relevant.

== Motivation ==
On a local dev wiki and in CI, where no gadgets are defined yet,
fetchStructuredList() is called on every load.php request and doing
uncached database look ups. This is because T39228 (stale cache
after Gadgets-definition was empty or created) was fixed by disabling
the cache until the page exists. This seems like a poor solution,
and commit I3092bcb162d032 recognises that the problem was not
understood at the time. I propose to instead cache it always and
purge it when the page is modified in any way.
Cold calling fetchStructuredList() accounted for ~170ms of ~400ms
when trying out debug v2 (T85805), thus making it significantly
slower and causing a chain of dozens of requests to pile up.
== Previously ==
* Legacy repo (MediaWikiGadgetsDefinitionRepo) only implemented
handlePageUpdate.
* handlePageUpdate was called from onPageSaveComplete for both
any page edit, and for creations in the experimental namespace.
* The experimental GadgetDefinitionNamespaceRepo is based on
ContentHandler rather than global hooks. This system does not
have a create-specific callback. It called update for edit/create,
and delete for delete. The experimental repo relied on create being
called from the global hook for the legacy repo, and update was
then called twice.
* There was no global hook for onPageDeleteComplete, thus the
legacy repo did not get purges.
== Changes ==
* Add onPageDeleteComplete hook to fix purges after deletion,
with the legacy repo now implementing handlePageDeletion() and doing
the same as handlePageUpdate().
* Fix handlePageUpdate() docs to reflect that it covers page create,
since onPageSaveComplete() called it either way.
* Fix experimental repo to include its namespace purge in
its handlePageUpdate() method.
* Get rid of now-redundant handlePageCreation().
* Get rid of handlePageDeletion() since its implementations would
now be identical to handlePageUpdate().
All these hooks and handle*() methods are just for a memc key
holding gadget metadata. We don't need to microoptimise this
on a per-page basis. Gadget edits are rare enough that purging them
as a whole each time is fine. We do the same in MediaWiki core
with ResourceLoaderGadgetsModule already.

Avoids expensive re-computations such as that of Action::getActionName, for
each gadget. It is now computed just once in the GadgetLoadConditions
constructor and stored.
This structure makes it cleaner to add more conditions down the line (such as
namespaces and content models - see T204201) and could be reused for user gadgets
(T36958).
