[libvirt] [PATCH REPOST 06/38] virlog: Introduce virLogSetFilters

[Erik Skultety]

This method will eventually replace the existing virLogParseFilters which
currently does both parsing and defining. However, each method should do one
thing only, so will the current virLogParseFilters method will be split into
parsing and defining, only to be swallowed by the entry-point API
virLogSetFilters.
