* Corrected Skin::generateUserJs() and Skin::generateUserStylesheet()'s comments: nothing override them anymore, also marked them as deprecated, only usage is action=raw&gen=(css|js)
Also make a few changes to the functions available. SpecialPageFactory::resolveAlias() now takes an optional subpage and returns array(<name>,<subpage>). Similarly merge getPage() and getPageByAlias(). There were many examples of (extensions particularly) making dubious assumptions about the presence or absence of subpages or canonical-ness.
I didn't deprecate SpecialPage::getTitleFor() as it's got over six hundred calls. I'm rather undecided on the best position of getPage()/executePath(). Although the latter needs cleanup anyway.
Also rearranges the loading order a little bit such that only=messages comes before only=scripts, and config comes before everything except startup and jquery+mediawiki
* Work around HipHop issue 314 (volatile broken) and issue 308 (no compilation detection) by adding some large and ugly compilation detection code to WebStart.php and doMaintenance.php.
* Provide an MW_COMPILED constant which can be used to detect compiled mode throughout the codebase.
* Introduced wfIsHipHop(), which detects either compiled or interpreted mode. Used this to work around unusual eval() return value in eval.php.
* Work around lack of ini_get() in Maintenance.php, by duplicating wfIsHipHop().
* In Maintenance::shouldExecute(), accept "include" as an inclusion function name, since all kinds of inclusion give this string in HipHop.
* Introduced new class MWInit, which provides some static functions in the pre-autoloader environment.
* Introduced MWInit::compiledPath(), which provides a relative path for invoking a compiled file, and MWInit::interpretedPath(), which provides an absolute path for interpreting a PHP file. Used these new functions in the appropriate places.
* When we are running compiled code, don't include files which would generate duplicate class, function or constant definitions. Documented the new requirements on the contents of Defines.php and UtfNormalDefines.php.
* In HipHop compiled mode, it's not possible to have executable code in the same file as a class definition.
** Moved MimeMagic initialisation to the constructor.
** Moved Namespace.php global variable initialisation to Setup.php.
** Moved MemcachedSessions.php initialisation to the caller in GlobalFunctions.php.
** Moved Sanitizer.php constants and global variables to static class members. Introduced an accessor function for the attribs regex, as a new place to put code formerly at file level.
** Moved Language.php initialisation of $wgLanguageNames to Language::getLanguageNames(). Removed the global variable, marked "private" since forever.
* In two places: don't use error_log() with type=3 to append to a file, HipHop doesn't support it. Use file_put_contents() with FILE_APPEND instead.
* Work around the terrible breakage of class_exists() by using MWInit::classExists() instead in various places. In WebInstaller::getPageByName(), the class_exists() was marked with a fixme comment already, so I replaced it with an autoloader solution.
* Also moved there generic <meta> and removed OutputPage::addDefaultMeta() with its $called static local variable which was breaking the output when generating multiple pages on the same request (rebuildFileCache.php, dumpHTML.php) since that function could only be executed completely once for all instances, and not once per instance
* Moved default module from OutputPage::output() to its own function and don't call it when executing a body only request, since it's useless in that case
* Call Skin::setMembers() from Skin::initPage() instead of Skin::outputPage()
'Courier new' is rendered with a constant size in both monobook
and vector skins. monospace is rendered too small under vector
with firefox/Linux.
Thus, this patch makes the font size consistent.
* merged <script> and if ( window.mediaWiki ) block with the one of mediaWiki.loader as stated in the doc
* removed dependency of $wgTitle
* the two only calls to this functions are in SemanticForms, but will not affect current version of MediaWiki:
** specials/SF_UploadWindow.php: this file is only used before 1.16
** specials/SF_UploadWindow2.php: the call is part of the else branch of a "method_exists( $wgOut, 'addModules' )" check, which means it's not called since 1.17
Also eliminate some duplicate code introduced into SpecialPage::headElement() in r61071 by calling Skin::getPageClasses() instead, and use $sk parameter instead of $wgUser->getSkin() to get skin name.
