LU-2591 lov: race between ptlrpc_rcv and umount/umount thread

The race which is refered here happens in the following scenario

1) mount runs but fails to communicate with some OSTs. Then the
   import objects which represent the OSTs are registered to
   a pinger list.
2) pinger succeeds to communicate with, at least, ONE OST. Then
   ptlrpc_rcv calls lov_set_osc_active to activate the OST and
   holds lov_refcount.
3) For some reason ... possibly mount finally fails or umount runs,
   ll_put_super is called
4) ll_put_super tries to disconnect all the OSTs with
   lov_disconnect and this func calls lov_del_target to set all
   the OSC's target->ltd_reap flags in order for lov_putref to
   handle all of them.
5) ptlrpc_rcv thread puts lov_refcount and if lov_refcount becomes
   0 here, the thread has to disconnect all the OSCs whose ltd->reap
   has been set.
6) Some OSCs' imports have still been LUSTRE_IMP_CONNECTING state
   because of (2), so ptlrpc_rcv thread has to wait for these
   import states to be changed to non-recovery states, such as FULL,
   CLOSED or DISCON at ptlrpc_disconnect_import.

Now that ptlrpc_rcv thread is waiting for the import states to be
changed to non-recovery states but ptlrpc_rcv is the one who is
supposed to change a recovery state to a non-recovery state, So
ptlrpc_rcv must hung, And mount/umount thread which has called
ll_put_super has to also wait for changing state at
ptlrpc_disconnect_import, so that thread must hung too.

LU-2775 fid: allow FID-on-OST in fid_seq_is_mdt()

The old 2.1 LASSERT_SEQ_IS_MDT() macro used fid_seq_is_mdt() in
several places to verify that a FID was "sane" for where it was
being used.  However, fid_seq_is_mdt() only checked FID_SEQ_OST_MDT0
through FID_SEQ_OST_MDT9 values, which immediately broke 2.1 clients
when FID-on-OST was enabled on 2.4 MDTs.

The use of FID-on-OST will be limited to only DNE MDTs for 2.4, but
clients should not LASSERT() on a value that it got from the network.
The use of LASSERT_SEQ_IS_MDT() is removed from clients, since this
is "validating" data from the network.  Even with this removal, the
fid_seq_is_mdt() macro is updated to allow FID_SEQ_NORMAL sequences,
as in 2.4, in case it is needed elsewhere.

LU-1331 changelog: allow changelog to extend record

Previously rename is split into two records, this isn't natural and
makes replication hard because rename needs two records, but they
may not be consecutive.

To solve this, allow Changelog to extend record, add fields sfid/spfid
in changelog record to store source/parent fid, and pack both source
and target name into the record.

Added changelog flag CLF_RENAME_LAST: rename unlink of last hardlink
of the target.

Added macro HAVE_CHANGELOG_EXTEND_REC: liblustreapi receives all
changelog records in changelog_ext_rec format.

As of the time of this patch, the nanosecond timestamp flag

LU-1623 mdt: Atomically update MDT export connection flags

MDT processing of connect requests currently updates the export
connection flags in two steps: client/server feature matching is
performed first, then much later various security-related bits are
removed as needed.  Certain error paths may leave the export flags
partially initialized.

A problem arises if multiple connect requests from the same client are
handled out of order, as may occur due to network disruptions. If the
last such request to be handled has a lower connection count than one
that already completed, it will be aborted with -EALREADY after having
modified the connection flags in the export.  However, the
security-related flags are left with incorrect values, as the
top-level connect handler skips setting these in the error path.
Replies to subsequent client requests may then contain unexpected
security information, causing the client to crash.

Similar issues may exist with other target types having non-atomic
export flag updates, and these should be addressed in follow-up
patches.

This patch makes the following changes:

- To avoid the problem described above, update the export connection
  flags atomically, and only in the successful case.

- To make this important atomic operation more conspicuous, move it
  from mdt_init_sec_level() to the top-level handler mdt_connect().

- Add a comment to mdt_connect_internal(), and delete a disabled code
  block from it.

- Correct debug message in target_handle_connect() to match code.
