This is a global search and replace of NS_IMAGE and NS_IMAGE_TALK with NS_FILE and NS_FILE_TALK respectively in all core files, excluding those already updated in step 1 (r44004).
* Fix regression from r37270: prop=categories paging was broken in generator mode.
* Fix drlimit=max, which was broken since r31384
* Use titleToKey() and keyToTitle() on title parts of the continue parameters in prop={links,templatelinks,categories,images}
* Use addQuotes() rather than strencode() in those same modules
* Don't trim message names in ammessages, it's stupid and undocumented
* Add $wgAPI{Meta,Prop,List}Modules to DefaultSettings.php explicitly
Doxygen documentation update:
* Changed alls @addtogroup to @ingroup. @addtogroup adds the comment to the group description, but doesn't add the file, class, function, ... to the group like @ingroup does. See for example http://svn.wikimedia.org/doc/group__SpecialPage.html where it's impossible to see related files, classes, ... that should belong to that group.
* Added @file to file description, it seems that it should be explicitely decalred for file descriptions, otherwise doxygen will think that the comment document the first class, variabled, function, ... that is in that file.
* Removed some empty comments
* Removed some ?>
Added following groups:
* ExternalStorage
* JobQueue
* MaintenanceLanguage
One more thing: there are still a lot of warnings when generating the doc.
