#2758 dtm: Derive Node ID from IPv4 address

[Anders Widell]

Continuation of ticket [#2653]. If OpenSAF is using TCP transport with IPv4 addresses, we don't need to require the presence of /etc/opensaf/slot_id or /var/lib/opensaf/node_id. Instead, we can create the file /var/lib/opensaf/node_id ourselves based on the IPv4 address of the node we are running on.

As a consequence, OpenSAF will now support any unsigned 32-bit integer except zero as Node ID.

nid: Make chassis_id, slot_id and subslot_id in /etc/opensaf optional [#2758]

The files chassis_id, slot_id and subslot_id in /etc/opensaf no longer have to
be present. When they are missing, OpenSAF will derive the Node ID from the TIPC
address or the IPv4 address of the node.

clm: Allow any unsigned 32-bit value to be used as Node ID [#2758]

Also fix the CLM API tests so that they longer assume that there is a node with
node ID 0x2010f in the cluster.

dtm: Derive Node ID from IPv4 address [#2758]

If the /var/lib/opensaf/node_id file doesn't exist when DTM starts, DTM will
create the file and use the IPv4 address as node ID. When using IPv6, the file
must still be configured manually. IPv6 support may be added in a future ticket.

As a consequence of this change, OpenSAF must now support any unsigned 32-bit
integer except zero as Node ID.
