Stephen Niedzielski 6b6bed86ed [docs] [dev] [PHP] [FeatureManager] revise docs and add DynamicConfigRequirement test
Address some feedback from I7a2cdc2dfdf20d78e4548f07cf53994563b234b3:

- Miscellaneous documentation improvements.
- Add a false case test to `DynamicConfigRequirement->isMet()`.

Sam Smith 84226b41b6 featureManager: Add DynamicConfigRequirement requirement
We expect the vast majority of requirements and features to be defined
in services as possible. However, there are some "complex" requirements
that require additional application/HTTP request state. Unfortunately,
service wiring is done before some of that state is available.

I65702426 attempted to work around this by requiring clients of the
Feature Manager to pass that additional state on every interaction with
the system. Those complex requirements would then select the parts of
the state that they required when it was required. However
implementations of \IContextSource are God objects and their use should
be limited.

Whilst reviewing I65702426, Stephen Niedzielski mentioned that the
application state being available is a requirement. This remarkably
simple solution:

- Keeps the Requirement interface and FeatureManager API free of God
  objects;

- Is true to the nature of the Feature Manager - it makes clear and
  centralizes the various checks for application state being available
  across the codebase; and

- Inject a Requirement implementations' dependencies at construction
  time

It just so happens that the $wgFullyInitialised variable flags whether
the application state is available...

Changes:

- Add the the FeatureManager\Requirements\DynamicConfigRequirement class
  and tests. The DynamicConfigRequirement lazily evaluates a single
  configuration value whenever ::isMet is invoked

- Register an DynamicConfigRequirement instance, configured to evaluate
  $wgFullyInitialised while constructing the Vector.FeatureManager
  service

Sam Smith d14caf2f11 featureManager: Add Requirement interface
FeatureManager::registerRequirement established the interface for a
requirement: its name and whether it's met.

However, the Feature Manager also needs to handle scenarios where a
requirement needs additional context before it can be considered met.
That context may not be available when the application is booting, e.g.
checking if the user is logged in; or the logic is complicated enough
that it should be under test.

Changes:

- Add the Requirement interface and update FeatureManager to work with
  implementations of it

- Maintain B/C by constructing an instance of a the SimpleRequirement
  DTO

Sam Smith 64bd4601b4 featureManager: Add typehints
I735fd640 bumped the required MediaWiki version to 1.31. That version
dropped support for PHP 5.x.

Wherever possible, update FeatureManager's methods to use PHP 7.0.x's
scalar and return type declarations.

Sam Smith 3f95820467 featureManager: Set -> Requirement
As was noted in https://phabricator.wikimedia.org/T244481#5859513, the
term "set" doesn't seem natural. Piotr Miazga (polishdeveloper, pmiazga)
and Nicholas Ray (nray) suggested a number of good replacements,
including "requirement." Serendipitously, this term is already used in
FeatureManager's documentation.

jdlrobson 0ba99a1e97 Make sure Vector skin preferences always follows skin
Sections can be nested. Using rendering/skin as the parent
means that Vector's skin preference will always come straight
after the skin preference and before Popups.

A change in core is needed to update the selector for the element which
shows/hides the subsection as well as provide a generic message key to
replace the one inside this repository.

Note: If the "Vector" specific heading is needed, we can achieve this
with a little more work but that is a conversation for another time.

jdlrobson 698752e38a [Dev] processTemplate used in one place
Moving all the templateParser calls to one function
so its easier to see how the template is composed.

The diff of changes to the stories folder highlight
the internal changes which are:

* html-portals replaced with html-sidebar in main template
* new Sidebar template added which outputs to html-sidebar
* Mention of "MainMenu" replaced with better understood "Sidebar"

This is precursory work to adopt templatePartials

Stephen Niedzielski de76ab59c1 [Special:Preferences] [PHP] Add skin version user preference and configs
Add a Vector-specific user preference to Special:Preferences for
toggling skin version, either Legacy Vector or the latest Vector.

The presentation of the new preference section and the default values
for anonymous, new, and existing accounts are configurable via
$wgVectorShowSkinPreferences, $wgVectorDefaultSkinVersion (to be used by
the feature manager in T244481),
$wgVectorDefaultSkinVersionForExistingAccounts, and
$wgVectorDefaultSkinVersionForNewAccounts. These configurations default
to the fullest experience so that third-party configuration is minimal.
See skin.json for details. The configurations are each tested in
VectorHooksTest.php.

When presentation is enabled, the new preference appears as a checkbox;
enabled is Legacy mode and disable is latest. There are a number of
unfortunate details:

- Showing and hiding a checkbox is supported by OOUI. Showing and hiding
  a whole section (Vector skin preferences, in this case) is not so this
  additional client JavaScript functionality is added in Core (see
  Iaf68b238a8ac7a4fb22b9ef5d6c5a3394ee2e377).
- Stylization as a checkbox is wanted. However, the implied storage type
  for OOUI checkboxes is a boolean. This is not wanted in the event that
  another skin version is added (e.g., '3' or 'alpha'). As a workaround,
  the preference is converted from a boolean to a version string ('1' or
  '2') on save in Hooks::onPreferencesFormPreSave() and from a version
  string to a checkbox enable / disable string ('1' or '0') in
  onGetPreferences(). There a number of test cases to help cover these
  concerning details.

Documentation for overriding the skin version as a URL query parameter
is provided in anticipation of T244481.

Sam Smith 9177c22365 features: Add minimalist feature manager
With complex additions to Vector's codebase like the Desktop Improvement
Program upcoming, it's important that we have a shared, intuitive
language to talk about features and their requirements. Centralising
the registration of features and creating an API satisfies does exactly
this.

This change introduces a greatly-reduced version of Piotr Miazga's
(polishdeveloper, pmiazga) original proposed API and associated
scaffolding classes for feature management in Vector, which itself was
based upon his work in MobileFrontend/MinervaNeue. This is done to
establish a foundation upon which we can build the more sophisticated
parts of Piotr's proposal in a piecemeal basis, thereby minimising risk.

Distinct from Piotr's proposed API is the ability to register sets and
features that are always enabled or disabled.

Additionally:

- A Vector.FeatureManager service is registered but not used

- A list of proposed immediate next steps is included

Jdlrobson 4d63b91152 Revert "Move Selenium test from mediawiki/core"
This reverts commit 68292ad0a8.

This test seems to be running on other skins that it should
not run on - for example Minerva. I'm not sure if this
is configuration related or test related.

I will follow up and restore these personally.
