== 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.

Locally these tests are failing for me on master every time.
In WMF CI, it seems they are passing right now, although they
too would start failing as of Ib27fd34fbfe7a7. My guess is that
my change there causes the service container to be initialised
earlier and thus causes the modified global to no longer be seen.
At the very least this should have been using setMwGlobals(), which
would have also avoided the issue by ensuring a service reset,
however use setGroupPermissions() since it's tailor made for this
purpose, and avoids potential problems later with default groups
not existing.

Overrides ResourceLoaderModule#getSkins() as introduced in core
with I08a1a59b4eab90d380ca8f874, so that skin-specific gadgets are
only registered client-side if applicable to the current skin.

The errorbox class will soon stop working. It and its successor
mw-message-box-error were designed to work with block elements, which
meant that its inline usage caused overlaps and partially unreadable
text above/below it. To fix this, and to be able to use the
Html::errorBox function, I switched to use block elements (<div>s).
Please note that *this causes visual changes* (see screenshots on
Phabricator), and while I tried to test it locally, I might have missed
edge cases, so do tell me if it breaks something.

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).

The validation appears to be occurring 4 times:
1. JsonContentHandler->preSaveTransform --> GadgetDefinitionContent->isValid
2. GadgetHooks::onEditFilterMergedContent --> GadgetDefinitionContent->validate
3. ContentHandler->validateSave --> GadgetDefinitionContent->isValid
4. RevisionStore->checkContent ---> GadgetDefinitionContent->isValid
Caching the validation result reduces it down to 2.
(Validation in GadgetHooks::onEditFilterMergedContent is to provide a more useful error message than what ContentHandler gives – which is just "Invalid content data".)

?withgadget query parameters allows for ad-hoc loading of gadgets
(after passing all other basic checks). This was recently added in
I5b30d4e.
In T29766#7611796 Gergo raised concerns about how this can be
potentially abused.
This patch aims to restrict the feature by giving gadgets latitude
to either use it or not depending on the nature of the gadget.
The patch does so by adding `supportsUrlLoad` option that gadgets
(maybe those deemed safe) can use it to opt-in to the parameter.
By default gadgets don't support it, so it can be enabled for each
on a case-by-case basis.

In addition, renamed several instance of $output to $parserOutput to
help readers (and code search!) differentiate between variables which
contain a ParserOutput and those which contain an OutputPage (esp.
since those two classes contain many similarly-named methods).

* Gadget::isEnabled() only requires a UserIdentity, not the whole User
* Gadget::isAllowed() only requires an Authority, not the whole User
Both of those interfaces are implemented by the User class, so this is
compatible with all existing code, and it's easier to call from code
that only has access to a UserIdentity/Authority.
