merge b_setattr into b_devel. The highlights:

- proper LDLM_DEBUG macro fix, for gcc 3.2 (850)
- failed open()s could cause deadlock; fixed (867, 869)
- stop cancelling OST locks when files are closed (481)
- overlapping XID spaces caused network corruption (851, 853)
- fix unsafe fsfilt counter arithmetic; change to atomic_t
- setattr_raw added, to do single-RPC, server-side setattrs
- fix crashy race condition between ptlrpc_free_req and osc_close
