do d_delete() for backfs dentry as vfs_unlink/rmdir do

- delay notification for audit_transfer in case of create
- remove unneeded list_head declaration

add audit flushing by demand. lctl flush_audit <mountpoint> will flush audit messages to syslog

remove setattr trick back

store setattr mask in nid for debug purposes

re-enable path restoring

turn off pathname restoring for debug purpose

- fix issue when more than needed chars in name are shown

r=alex
- get mds num from obd for just created file/directory to store
  correct value in audit log

r=alex
- add audit flag on UNNAMED dir to enable audit inheritance on newly created objects

changes in auditing of failed operations when audit is set on directory

 - couple unused vars have been removed

audit on file didn't work on unlink due to loss of audit setting. Now audit mask is saved in smfs_inode_info also.

lctl fix for setattr
remove unused symlink opcode

 smfs didn't update backfs file pos with smfs file pos value before operation. This were critical for llog processing in some situations.

type in lustre id are not always correct.(client don't update type in lli_id;
id for cross-ref inode never store mode)

 - turn off audit for setattr/unlink on OSS
 - add few checks for stored lustre_id

- small cleanups, more detailed error messages, fied error codes in ost_rec_create_pack(),
  fixed mixed declations and non declation stuff in osc_get_info()

- set smfs flags on group subdirs

- fix wrong record length

- store node id in audit records on OSS
- move audit hook from filter_commitrw() to fsfilt_smfs_map_inode_pages()
- fix invalid nid in osc_get_info()
- rework stat/open audit hooks to store file lustre id, not parent one
- audit errors while stat/open

- 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.

- transfer only one audit record on one notify.
- make sure the connection has been established before using the mdc export on name reconstruction.

- only files on OSS should be audited
- audit_fill_id_rec is valid only on mds. Moved to mds_audit.c
- audit_ost_get_id() gets lustre id for OSS object for audit log

- remove unneeded debug
