R memory handling standardisation

Browse source 
Replace R_SWIG_EXTERNAL and R_SWIG_OWNER with the standard equivalent
macros. I can't see where these were actually used, but in case they are,
equivalent backwards compatibility can be obtained using:

  #define R_SWIG_EXTERNAL 0
  #define R_SWIG_OWNER SWIG_POINTER_OWN

SWIG_MakePtr does not seem to be used within the R SWIG code base so I
havn't added the above as backwards compatibility macros.
There seems to be no memory management in R. I've made this change
to fit in with the rest of SWIG though in preparation for an upcoming
commit to use the same shared_ptr macros as is used elsewhere.
