I think the version with virStringSplit would need some fine tuning since in its
current form it will not free the memory for the failure cases..Comments ?

Also can some expert here provide some tips on whether in this particular
circumstance it should be fine to allocate/realloc/free memory inside the while
loop.  Would be very helpful..
