Change subject: Make WebRequest objects time-aware
......................................................................
Make WebRequest objects time-aware
* Deprecate $wgRequestTime in favor of $_SERVER['REQUEST_TIME_FLOAT'], which is
more accurate. Because $_SERVER['REQUEST_TIME_FLOAT'] is only set for PHP
5.4+, set it to microtime( true ) in Setup.php for back-compatibility.
* Modify the WebRequest constructor to take an optional request time parameter
which defaults to microtime( true ) if unset.
* Use that to provide WebRequest::getElapsedTime(), which gets the time since
the request was initiated.
* In wfLogProfilingData(), get the user and request objects from the context
object rather than from global scope.
