uuid of client mdc and osc will be modified in mds ost add

tmp fix about ost add/del, reset osc uuid in mds, but not reset mdc uuid in mds

  shouldn't release crypto subsystem before, because it's used in ll_clear_inode()

revert back the fix for b7379, it is not right.

a tmp fix for b7379.

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

 - let's try to catch the case when late MDS_CLOSE updates attrs. from
   out-of-date i/o epoch

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

fix bug 7348, when chmod, should recompute mac

land ost add/del to HEAD

- never leave non-handled close works (in close thread)

- 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.

- set only LOV_EA in mds_reint_setattr() in the case of CMOBD reint as setting sid and pid will confuse master MDS.
- set mds_security to "null" in lustre_connect_mds() if not specified or panic is possible.

land crypto api

 - more debugging info

 - concurrent lock cancelling might find inode dead while it's not yet

 - stop progress and dump a log for debugging purposes

  5984 - oops in mdc_set_lock_data
         we must drop lookup lock in ll_clear_inode()
  7216 - abort due to missed clients
	 replay already committed (open/close rpcs) requests
	 even if some clients haven't connected in time and
	 got evicted
  7057 - sanity: test_66: /mnt/lustre/f66 blocks 0 < 8
         send close rpc only when all dirty pages are written
	 (otherwise i_blocks isn't valid)
  6817 - don't update attrs. on mds if the client hasn't modified file
         using openhandle being closed

 * "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.

 - protect lock->l_resource from concurrent ldlm_lock_change_resource()

  - 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).

 - b_ldlm_newlocking landed. we need it to pass some CMD2 performance tests
   NOTE: the new locking rules introduced by the patch are still experimental!

- putting file fid into o_inline for cases when crow object may be created. It will be used later for storing into OSS object EA what is needed for quota.

cache fixes.

- setting owner/group on OSS (needed for quotas)

- some fixes:
  - deadlock on soc client lock.
  - idr_remove() issue.
  - forwarding to wrong MDS in lmv_link()
  - f_dput(dentry) before using it in filter_lvbo_update()
  - filter_sync() assert(group > 0) due to missed GROUP flag oa->o_valid in ll_fsync().
  - cleanups, comments and more debugging messages.
  - jump to wrong label in mds_create_objects() on error path.
  - few missed/wrong ENTRY/RETURN things

 - don't confuse OST by non-zero connect flags from clients. OST expects
   group number while only MDS can have a group
