Description

The goal of this ticket is to add the support for the patched clients 1.8 to be correctly handled on the 2.x fixed side.

The patch has to contains next two parts:
1) client side change (for the https://bugzilla.lustre.org/attachment.cgi?id=30902) - here we need to add new flag for 1.8 clients which has the change from this patch (OBD_CONNECT_FLOCK_OWNER).
2) server side change for the 2.x http://review.whamcloud.com/#patch,unified,2193,2,lustre/ldlm/ldlm_lock.c patch and extend it with the flag OBD_CONNECT_FLOCK_OWNER checking and call the ldlm_flock_policy_wire21_to_local() function for this case.
