Edward Tomasz Napierala 2bfc50bc4f Add two new system calls, setloginclass(2) and getloginclass(2). This makes 
it possible for the kernel to track login class the process is assigned to,
which is required for RCTL.  This change also make setusercontext(3) call
setloginclass(2) and makes it possible to retrieve current login class using
id(1).
