Removed most exit() calls from the MediaWiki core, by replacing them with either a throw or by classic error checking. OutputPage::fatalError() and similar functions are deprecated, use either OutputPage::showFatalError() to return control or throw new FatalError() to relinquish it. Backwards compatibility of all interfaces has been maintained, thus extensions should continue to work and can be ported at a later date.

Merged localisation-work branch: * Made lines from initialiseMessages() appear as list items during installation * Moved the bulk of the localisation data from the Language*.php files to the Messages*.php files. Deleted most of the Languages*.php files. * Introduced "stub global" framework to provide deferred initialisation of core modules. * Removed placeholder values for $wgTitle and $wgArticle, these variables will now be null during the initialisation process, until they are set by index.php or another entry point. * Added DBA cache type, for BDB-style caches. * Removed custom date format functions, replacing them with a format string in the style of PHP's date(). Used string identifiers instead of integer identifiers, in both the language files and user preferences. Migration should be transparent in most cases. * Simplified the initialisation API for LoadBalancer objects. * Removed the broken altencoding feature. * Moved default user options and toggles from Language to User. Language objects are still able to define default preference overrides and extra user toggles, via a slightly different interface. * Don't include the date option in the parser cache rendering hash unless $wgUseDynamicDates is enabled. * Merged LanguageUtf8 with Language. Removed LanguageUtf8.php. * Removed inclusion of language files from the bottom of Language.php. This is now consistently done from Language::factory(). * Add the name of the executing maintenance script to the debug log. Start the profiler during maintenance scripts. * Added "serialized" directory, for storing precompiled data in serialized form.
