A terminating line break has not been required in wfDebug() since 2014, however no migration was done. Some of these line breaks found their way into LoggerInterface::debug() calls, where they mess up the formatting of the debug log. So, remove terminating line breaks from wfDebug() and LoggerInterface::debug() calls. Also: * Fix the stripping of leading line breaks from the log header emitted by Setup.php. This feature, accidentally broken in 2014, allows requests to be distinguished in the log file. * Avoid using the global variable $self. * Move the logging of the client IP back to Setup.php. It was moved to WebRequest in the hopes that it would not always be needed, however $wgRequest->getIP() is now called unconditionally a few lines up in Setup.php. This means that it is put in its proper place after the "start request" message. * Wrap the log header code in a closure so that variables like $name do not leak into global scope. * In Linker.php, remove a few instances of an unnecessary second parameter to wfDebug().
