Add ioctl-based AFS calls for Solaris 11

Add ioctl-based AFS calls for Solaris 11

Switch from using syscall-based AFS calls to ioctl-based AFS calls,
since syscall 65 was repurposed in some kernels in Solaris 11 and
OpenSolaris. Update the provided afs init script to accomodate the
additional steps needing for starting the AFS client.

Partially based off of some work by Derrick Brashear.
