[libvirt] [PATCH] fix memory leak in __virStringListFree

[David Lively <dlively virtualiron com>]

Currently __virStringListFree is freeing only the list nodes, but not
the strings on the list (and neither is anyone else freeing these).
This small patch fixes that, and documents the two __virStringList
functions.
