[libvirt] [PATCH v2 10/20] virlog: Introduce virLogParseFilter
Same as for outputs, introduce a new method, that is basically the same as
virLogParseAndDefineFilter with the difference that it does not define the
filter. It rather returns a newly created object that needs to be inserted into
a list and then defined separately.
