Add LNET router traceability for debug purposes

If a checksum failure occurs with a router as part of the IO path, the NID of
the last router that forwarded the bulk data is printed so it can be
identified.

Description: Be more lenient with linux clients before warning (by Andreas)
Details: This fixes Linux clients so they allow one major Lustre release update
         before they warn.  It also makes the setting of the version a lot
         easier by using OBD_OCD_VERSION(0,0,1,32) instead of having to calculate
         it directly.

Change timeouts on Cray XT3.

Description: client incorrectly hits assertion in ptlrpc_replay_req()
Details    : for a short time RPCs with bulk IO are in the replay list,
       but replay of bulk IOs is unimplemented.  If the OST filesystem
       is corrupted due to disk cache incoherency and then replay is
       started it is possible to trip an assertion.  Avoid putting
       committed RPCs into the replay list at all to avoid this issue.

Description: RPCs being resent when they shouldn't be
Details    : Some RPCs that should not be resent are being resent.  This
	     can cause inconsistencies in the RPC state machine.  Do not
	     resend such requests.

Fix 2.4 kernel compile error introduced by 10866 landing (missing typecheck).

land posix flock patch of Don.

 - don't use req as we've lost our reference after ptlrpc_set_add_new_req()

  without involving OST

 - show error message always to simplify bug catching

 - additional debug info

- fixes for making liblustre at least buildable (including fixes to compilation bug found by Brian recently)
