    graph: fix updating edge with active graph
    
    After creating at least one graph and calling rte_node_edge_update to
    add a new edge on a node which is in use in the graph, the node memory
    is reallocated but the active graph still has a pointer to the freed
    memory.
    
    When destroying the graph, it causes a use-after-free error detected by
    libasan:
    
    ERROR: AddressSanitizer: heap-use-after-free

    Use malloc+memcpy and add an internal function to replace all references
    to the old node memory before freeing it.
