    pluto: kernel.c: tidy teardown_half_ipsec_sa
    
    - clarify and simplify handling of redirection.  Don't hack the
      connection!
    
    - bug fix?  Previously, if the kernel supported grouping of
      SAs, a bare IPcomp SA would not be deleted.  Also, in this case
      any redirection hack would not be undone.
    
    - reduce code duplication between the case where the kernel
      does support grouping and where it doesn't.
    
    - protos[].proto is a pointer.  Use NULL, not 0
    
    - reduce scope of autos by declaring them just before first use
