V2 changes:
-Rebased over #1180 (Cloud resilience patch).
-During headless state, OpenSAF may get stopped on payload with NTF app running.
Since OpenSAF is not running on the payload, any A.01.02 NTF client should not
be served on
this node and this client should not be recovered. After first controller
comes up, A.01.02
client will not be recovered and application will get SA_AIS_ERR_UNAVAILABLE
upon which an
app can call saNtfFinalize() for freeing the resources.
Changes include:
-maintain SAF version.
-minor version is updated from 01 to 02.
-ntfa will get NTFSV_CLM_NODE_STATUS_CALLBACK from NTFS for membership status
of node.
-check is included in all apis, excluding saNTfFinalize(), to return
SA_AIS_ERR_UNAVAILABLE
if node loses CLM membership.
