especially if the mgc is shared by multiple targets.
So once mgc enqueue is failed, it will give another chance to
wait the import to recover, if the import comes back in time,
it will try to enqueue again. Otherwise it will use local config log.

staging: lustre: ptlrpc: remove old protocol compatibility

Some old protocol compatibility workarounds are still present in
master that should have been removed when LUSTRE_MSG_MAGIC_V1 was.

In particular, the process for upgrading LUSTRE_MSG_MAGIC_V1 to
LUSTRE_MSG_MAGIC_V2 had the client to connect to the server with the
V1 protocol with op_flag=MSG_CONNECT_NEXT_VER set, and if the server
supported the V2 protocol it would reply with LUSTRE_MSG_MAGIC_V2.
This ensured that if the new client connected to an old server the
connection would be allowed.  However, even with V1 protocol support
removed, the 2.x clients are still connecting with NEXT_VER set.
In b1_8 this flag was contingent on LUSTRE_MSG_MAGIC_V1 being used,
which is how it should have been in 2.x as well.

A few other cleanups are be done at the same time:
 - disallow 1.8 clients (or at least those that don't understand
   OBD_CONNECT_FULL20) so we can remove workarounds for 1.8 clients
 - remove support for pre-2.1 DLM flock lock handling
 - don't workaround the lack of MDS_ATTR_xTIME_SET flags in setattr
 - always set MSGHDR_CKSUM_INCOMPAT18 (it can eventually be removed)

staging: lustre: ldlm: Do not use cbpending for group locks

Currently, the CBPENDING flag is set on group locks when
the osc lock above them is released (osc_cancel_base).

This results in a situation where a new group lock request
on a resource does not match an existing group lock because
LDLM_FL_CBPENDING is set on the existing lock.

So two group locks are granted on the same resource, which
is not valid, since a given client can only have one group
lock on a particular resource.

Since group locks are manually released and not called back
like other LDLM locks, the CBPENDING flag doesn't make
sense. Since they must be manually released, they also
cannot go in the LDLM LRU cache and must be fully released
immediately once they are no longer in use.

This was previously accomplished by setting CBPENDING when
the corresponding osc lock is released, but as noted above,
this prevents the group lock matching some future lock
requests.

This patch uses the fact that group locks have an l_writers
reference which they keep until they are manually released,
so we remove them when they have no more reader or writer
references, without checking cbpending.
