glib's 'g_autoslist()' doesn't support lists of

type alias 'virGSListString' so that we can register an 'autoptr'
function for it for simple usage of GSList with strings.

So, GSList is a singly linked list. This doubles memory usage because
for every string we have to also store pointer to next. Is O(n^2) that
bad so that we have to sacrifice memory complexity?
