- NtLoadDriver APIs refactor/improvent:
* Move loading of a driver to the common (in future) routine IopLoadUnloadDriver (name taken from http://wasm.ru/forum/viewtopic.php?pid=166891). * Fix a bug: NtLoadDriver should always load drivers in a context of the system process, explanation here: http://www.osronline.com/showthread.cfm?link=114687 * Reformat NtLoadDriver's code. svn path=/trunk/; revision=29370
