    pluto: a few more tweaks to add_connect
    
    - ensure alg_info_ike and alg_info_esp fields are initialized to NULL
      (initializing a pointer's raw memory to 0x00 is not guaranteed to initialize
      the pointer to NULL)
    
    - there are two distinct err_buf variables.  Reduce the scope of one
      so that their scopes don't overlap.
    
    - make it manifest that c->alg_info_esp is set only once to a non-NULL value.
      This makes it clear that there is no leak caused by an apparent second
      assignment.

    pluto: ike_alg_show_connection: combine declaration and initialization
    
    This reduces the scope of the variable st and eliminates the portion of the
    scope where it was uninitialized.
