* This patch improves the performance of an
ext:Gadgets regular expression which helps parse
out sections of the gadgets definition page.

(cherry picked from commit f2bc65a518)
* Remove most APCu logic, including the reverse checking of WANCache
touch time to validate the APCu key
The APCu expiry had a 7-15s blind TTL before this check took place.
Keep the conservative part of this (blind TTL). This should be
more than enough to debounce memcached traffic.
* Simplify WAN handling with plain key and delete (using the default
holdoff tombstone, which should take care of edge cases like second
DC warming up the WAN key shortly after a delete).
* Fix incorrect method doc about being by section. The returned
list is not by section.

== 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.

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.

Links the following entries in gadget definitions to the associated page:
- scripts
- styles
- datas
- peers
- dependencies (only when they are also a gadget)
- category (links to MW message page)
- messages
unserialize(serialize()) hack is a bit ugly, but it works.

When using the Gadget definition: namespace, link to the definition
pages from Special:Gadgets. Also change the wording of the links
to edit the names of the gadgets, to disambiguate them.
Change-Id: I327a4cfa9846edec60e1aaafc674cd66f4e0beae
Allow specifying page actions ('view', 'edit', 'history', etc) in
gadget definitions. If specified, the gadget is run only on the given
page action(s).
This is especially useful for default gadgets like RefToolbar[1] and
TextReactions[2] that only need to be loaded while editing.

The parsed content of JSON files in the gadget is made available from the
gadget's JS files via require(). That is, MediaWiki:Gadget-data.json (or
Gadget:data.json) is available as `require('./data.json')`. This is
supported for both MediaWikiGadgetsDefinitionRepo and
GadgetDefinitionNamespaceRepo. The JSON parsing is done server-side.
JSON can only be used in "package" gadgets - in which the JS files can
also be invoked via require().
Also added a test for GadgetResourceLoaderModule.

Previously attempted in 82281d82d0,
reverted in 7c4ac597e2.
This gives each section and each gadget's entry an `id` attribute,
which can be used for linking, as requested in T126962. Existing user
options still match the new preferences.
It also probably makes future improvements easier. No one understands
multiselects with subsections.

When viewing pages, the 'withgadget=' query parameter can be used in
the URL to load a gadget that isn't enabled by the user's preferences.
The gadget is only loaded if all other conditions are still satisfied
(supported skin, supported targets, required user rights).
