[libvirt] [PATCH REPOST 18/38] virlog: Introduce virLogFilterListFree

[Erik Skultety]

This is just a convenience method for discarding a list of filters instead of
using a 'for' loop everywhere. It is safe to pass -1 as the number of elements
in the list as well as passing NULL as list reference.
