Add new SetTokenEx pioctl
This change implements the new, XDR based, SetTokenEx pioctl. This
pioctl permits sending multiple tokens, of multiple types, into the
kernel in a single pioctl call. This patch provides a kernel
implementation of the pioctl, and a new library function
ktc_SetTokenEx, which will use either the new pioctl, or fall back
to the old one should SetTokenEx not be available.
