At a slightly larger memory expense allow stealing of items from the
string array returned from vshStringToArray and turn the result into a
string list compatible with virStringSplit. This will allow to use the
common dealloc function.
This patch also fixes a few forgotten checks of return from
vshStringToArray and one memory leak.

Why not to destroy the use of vshStringToArray, and convert to
virStringSplit? and the comment of vshStringToArray should be updated,
since the method for free'ing the memory is different now, if we keep
using it.
