Allocate a route entry.

[in] | dynamic | Whether the route is dynamic |
The returned route has no linkset associated yet, user must associate it using API ss7_route_set_linkset() before inserting the route into its routing table.
Fields priority and qos_class may be set before inserting the route into its routing table:
Use API ss7_route_insert() to insert the route into its routing table.
The route entry allocated with this API can be destroyed/freed at any point using API ss7_route_destroy(), regardless of it being already inserted or not in its routing table.
Dynamic routes are not configured by the user (VTY), and hence cannot be removed by the user. Dynamic routes are not stored in the config and hence they don't show up in eg "show running-config"; they can be listed using specific VTY commands like "show cs7 instance 0 route".

The route allocated and returned by this API is already inserted into the routing table, with priority and qos-class set to 0. If you plan to use different values for priority and qos-class, avoid using this API and use ss7_route_alloc() + ss7_route_set_linkset() + ss7_route_insert() instead.
