To improve performance, disable most logging (for debug purposes)
by default.  VFSTRACE, RPCTRACE, and DLMTRACE are now off by
default, and HA includes contains fewer messages.

Check that request is still eligible for replay in mdc_set_replay_data()
before doing anything.

  1) ll_file_open() has a request with capa
  2) the inode is already opened, so we close just received openhandle
  3) mds fails, recovers, ptlrpcd replays open request
  4) ll_set_capa() finds capa in replayed open request non-swabbed - BUG

  - mds_getattr() returns regular errors in rq_status
  - mdc_interpret_getattr() interprets it properly

 - setup cr_replayid immediately because it might take long to get to
   mdc_set_open_replay_data() and replay can happen in meantime

fixes:
* also round for short expiry, in case timer might miss.
* add mds_mfd_put() because mds_handle2mfd() will add ref.
* filter_verify_capa() logic error.

change error msg to warning.
some cleanup.

  without involving OST

fixes:
* previous implementation doesn't support multi-open/truncate by different
  users on the same inode.
* update DLD.
* cleanup.

fixes:
* pack fid for direct io.
* seperate verify_fid from verify_capa to fully support truncate.
* debug message cleanup.

add support for ost-authorization-revocation and fid verification.

- md_close() chnaged to use mdc_op_data like other md_* functions instead of using obdo.
- fixed prototype declaration for llapi_lov_get_uuids() - bug #6900
- fixed error message in ll_gns_mount_object() - bug #7146

- a lot of fixes about memory allocation/freeing:
  - checks is memory is actually allocated by OBD_ALLOC() before sing it and do appropriate
    actions otherwise.

  - fixed many leaks on error paths.
  - fixed missed OBD_FREE(capa_hash) in capa_cache_cleanup()

- fixed few on stack allocatoins of mdc_op_data in new landed stuff.

- in smfs_mount_cache() fixes correct cleanup in the cases of memory allocation failures.
  Do mntput() for new mounted cache_mnt on error path.

- in smfs_umount_cache() nullify smb->smsi_cache_ftype and smb->smsi_ftype after freeing
  them, to prevent attempt to free again if smfs_umount_cache() is called second time.

positioning: make remote acl always occupy 2 buffers, just like local
acl.

some fixes about crypto api

 - dedicated threads for serving OST_DESTROY and MDS_CLOSE

land crypto api

 * "EA" is used for lustre internal metadata ea. so change user ea's name to
   "XATTR", including ACLs.
 * remove a unnecessary param from md_getattr().
 * various more fixes.

- in cmobd fixed init of EA size for LOV with multiple OSTs as master. As there is no another way MD layer is getting asked for correct lovdesc, as it is needed in some cases. Thus, added handler for "lovdesc" nfo key to all MD devices.For instance, cmobd asks LMV for lov desc, it asks first MDS and MDS has it from LOV anyway.

- fixed possible LMV obd corruption in cmobd_init_ea_size() where it unconditionaly accessed u.cli things abd modified them whereas here was LMV.

- removed obd_getready() as it is not needed anymore. It was needed earlier for CMOBD to get LMV ready before asking rootid, etc. Currently alternative way is found. lmv_get_info() is just taking care of LMV targets readiness it self.

- fixed layering violations and possible oopses in cmobd data code where master export was unconditionaly expected as LOV and accessed as LOV what could be wrong in the case of using OSC. OSC using with no LOV is deprecated, but in principle is possible.

- in LMV module many functions are added by static specificator as they are not used outside of their object files.

  - change LUSTRE_MDC_NAME (and others) to form like OBD_MDC_DEVICENAME to be coherent with
    OBD_LMV_DEVICENAME and others. Because some OBDs used one form and others used another one.

  - removed different guesses of OBD types from name of some functions in cmobd. Say
    cmobd_find_master() now is called cmobd_find_obd() as all it does is finds obd
    by uuid and may be used not only for finding master. Also cmobd_lmv_obd() is renamed to
    cmobd_md_obd() etc. Improved function (a bit smaller of code) wich looks for master.

- in memory leaks detector do not remove memory track in case of freeing memory chunk different
  of size. marking it instead as such to show in final log of leaks with special hint.

- fixes in lconf. COBD and CMOBD should use LMV and LOV devices with diffrent names to avoid
  issues in the case when both they run on the same node (like in test 45) and try to setup
  and clanup the same device twise (from lconf).

  mdc_commit_close() as in some cases we may have no close at all
