r=adilger (original patch and inspection of updates to it)
Some updates so that acceptance-small.sh can be run on a patchless client
using a remote OST and MDT.
Credit goes to adilger.  Most of this is his work.  I just shepherded it
through the process.
My batch of updates to the same end is still to come.  Still to be inspected
in fact.

Fix lov_mds_md in mdd_create_objects error handler.
Checking whether obd_fail before fsfilt_start.
Free fcc no matter whether fsfilt_commit success or failed.

other tests run. For example runtest.sh, replay-single.sh

It is a deadlock between quota and journal.

play nicer with parameters on logs upgraded from 1.4.x
- allows updates for old logs whenever we can (i.e. ok for mdc, not for osc)
- allows updates for everyone if --writeconf is specified at tunefs upgrade
time (requires entire fs to be stopped though)
- allows updates of failover partners if --writeconf is specified
- fixes various other little bugs and error messages
- adds a couple of regression tests for upgrading from 1.4.6

some minor fixes about sanity-crypto test scripts

land crypto api

some fix and cleanup for WB test script

luster installed, which cause confusion of which lconf/lmc/lctl will be
used. We put $LUSTRE/utils and $LUSTRE/tests at the head of $PATH env
to ensure the tools in source tree will be searched at first. This should
not affect the tests by install, but if we got problem we'll back this
commit out.

 * remote uid/gid handling
 * various gss fixes
 * fix broken local ACL

MDS_BACKFSTYPE and OST_BACKFSTYPE are defined for this.
FSTYPE is ldiskfs for 2.6 kernel by default

Fix replay-single.sh and recovery-small.sh so they can run with the
default lmv config or "-f cfg/local.sh" config.

I haven't re-tested the AMD functionality since landing, but I did
test iozone and dbench to ensure sanity.

b_cmobd_merge should not be used for any further development or testing!

cMD_PRE_CMD_SMASH are the relevant tags.

The pre-smashing contents of HEAD will be committed by yury into b_cmd as a
merge of the two branches.  These will be stabilized on b_cmd and eventually
landed onto HEAD.

- add a new test (18a) to use lctl --deactivate to confirm page cache is
  cleared after invalidation.
- rename 18 to 18b, and increase wait to ensure the cache is checked after
  recovery

r=zab (partial)

Better handling for OST eviction.  Fixes for clearing the page cache,
imp_invalid handling, and improved import_event interface. Also
includes the tests and fixes added from 2732; one of those tests does
not yet passed so it is excepted for now.

The principal change here is ptlrpc_connect_import and recovery are
merged and are now asynchronous and are run on ptlrpcd.

This branch also includes fixes for

  2477 (this was the initial bug)

  2355 recover for initial connections

  1934 (b_1934 was merged directly to b_recovery)

  1901 block all file creations until orphan recovery completes

  2423 client remove rq_connection from request struct

  2640 conf-sanity test_5, and proper cleanup in umount when
       cleanup log is not availale.

  2670 recovery timer race

  2532 mdc_close recovey bug

And few others that werent' filed.
