GadgetRepo is an abstract class based off of the implementation in the
RL2 branch.
It is a singleton that provides basic methods to construct and interact
with Gadget objects.
The MediaWikiGadgetsDefinition class is an implementation of GadgetsRepo
that parses the "MediaWiki:Gadgets-definition" page for gadget
definitions.
Tests were left in place to demonstrate that no functional changes have
been made aside from relocation of code. Some tests should be moved to
separate files in the future.
Bug: T106176
Change-Id: I3e802889f6f495783f4dbac65c2a8cefa824a778
MediaWiki core change I04b1a384 added support for i18n of API module
help. This takes advantage of that while still maintaining backwards
compatibility with earlier versions of MediaWiki.
Once support for MediaWiki before 1.25 is dropped, the methods marked
deprecated in this patch may be removed.
