* User::getRights(), User::isAllowed() and User::getGroupPermissions now optionally accept a namespace parameter. If not set, it will check whether the user has the right for all namespaces.
* Anything that uses Title::getUserPermissionsErrorsInternal() automatically supports per-namespace permissions. This includes Title::getUserPermissionsErrors and Title::(quick)UserCan.
* Fix tests that set User::mRights
The next step would be to change all User::isAllowed() to Title::quickUserCan or pass the namespace to User::isAllowed().
This is not merged with the r86131 change to Article::getParserOptions() since I don't see the point for the new function yet.
Reenabled its test ArticleTablesTest which was disabled in r85618
* Block.php: Set mExpiry to the value we store in the database, so that Block::equals() returns true. Fixes BlockTest::testInitializerFunctionsReturnCorrectBlock.
* In Title::checkUserBlock(): Convert message parameters to plain strings to make strict comparisons work. Fixes TitlePermissionTest::testUserBlock().
* ApiBlock.php: Follow-Up r85166, add 'Confirm' parameter to data array. Fixes ApiBlockTest::testMakeNormalBlock().
* ApiQueryTest.php: Use $wgMetaNamespace instead of $wgSitename to account for customizations.
* RandomImageGenerator.php: Use default value for constructor param to prevent fatals.
* ApiTestCaseUpload.php:
** Fix undefined variable $fileName.
** Remove stray ini_set statements, they don't belong there. Especially ini_set( 'error_reporting', 1 ) will effectively disable all reporting, which makes errors hard to track.
* ArticleTablesTest.php: Put testbug14404() in group Broken, as the fix for the bug has been reverted in r83868.
