* noticed difference between userspace and kernel x86_64 __u64 etc typdefs

*   noticed difference between userspace and kernel x86_64 __u64 etc typdefs
    and adjusted LPU64 etc in <libcfs/linux/kp30.h> appropriately

*   libcfs_pause() -> inline cfs_pause() in <libcfs/linux/linux-prim.h> and
    made more use of it

*   cleaned up NAL loading/instantiated console messages

*   fixed reconnect_interval in connection NALs, where I'd left out * HZ

*   made ???_npeers atomic again; using ???_global lock round the decrement in
    ???_destroy_peer() could deadlock.

*   fixed uninitialised list in vib:kibnal_peer_connect_failed()

*   changed to "nicer" format for /proc/sys/portals/routes

*   more x86_64 testing
