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

Phase 1 of LNET Reorg
r=eeb
r=pjk

forget lprof->lp_gkc in profile delete

 - dump time ost_brw_write() spent waiting for bulk completion

  without involving OST

minor fix:
* for partial write only search capability once.

 - couple unused vars have been removed

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

r=ericm

 - keep FLSIZE for non-regular files

a tmp fix for b7379.

a minor reorganization of capability code.
some cleanup.

previous fix was wrong

- enable audit on every child in dir while setting audit on that dir.

- add special handler for auditing access failures

- all stats gatherd in OSC debugging time (cache loading, etc.) moved to proc. Added new proc file ./cache_stats showing them.
- some RPCs related new stats added to ./rpc_stats

some updates in sanity-crypto.sh

shouldn't touch this.

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

- move reint auditing into mds_audit
- auth audit should use child inode if it exists to recognize correct audit setting

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

b7148 typo fix

tmp hack fix for b7148, now we use confobd to write config log, so mds_config_version
is useless in config log name defination. Remove it temporarily.
b7148

r=tappro

 - avoid possibility to FLSIZE being sent back to client w/o checking

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   out-of-date i/o epoch

- enabled filter_tally_write() to have brw_stats on OST

b7375
when decrypt page, should decrypt the whole page array, not only the first
page

 - we should allow processing for request being resent during request
   replay stage. but we may do that only when all clients are connected
   (or after evicting clients that haven't connect in time)
