Large partial cleanup of ntoskrnl internal headers, mostly to delete obsoleted or non-useful headers, to reformat some horrible tab, spaces, etc mixups, and to move to NDK some public structures and remove all the include headers so that the standard one can be added. Note the word partial, meaning more will come in order to fully fix the mess.
