* Added the ability to compile extensions. The build process is bootstrapped by running MediaWiki in interpreted mode. Extension setup file inclusions are slightly modified in a way that makes them register themselves for compilation. Then the same LocalSettings.php uses the compiled extension setup file when the compiled binary runs. * Tested with Cite and ParserFunctions. The code which lets you have an extensions directory in a place other than $IP/../extensions is untested. * Simplified WebStart.php slightly by using a custom $_SERVER variable to mark compiled mode. It will break if you don't use the supplied server.conf, but that will break a lot of things so don't do that. * Fixed the core web entry points to include WebStart.php in compiled mode instead of interpreted. * Made the build directory configurable. This is mostly so that I can grep the source tree without seeing loads of generated C++. * In server.conf, added a rewrite rule allowing a /wiki/$1 article path. * Removed server.conf log file location "/dev/stdout", breaks when you switch user * Disable static content cache, breaks horribly when you set SourceRoot to a directory containing 7GB of files. * Rewrote the run-server script in PHP, mostly to support the configurable build directory feature. * Added an option to the run-server script to allow running in interpreted (hphpi) mode.
