[libvirt] [libvirt-sandbox PATCH v3] Add filter support.

Wednesday, 8 January 2014

This patch adds two new classes, filterref and filterref-parameter.
Network interfaces can now have an associated filter reference with any
number of filterref parameters.  Also added filter= option to
virt-sandbox tool.

---
V2:

- Changed set_filter to set_name and get_filter to get_name.

V3:

- Added type checks on all public methods.
- Call setters on property set.
- Fix install_property flags.
- Remove unneeded HANDLE defines.
- Add missing g_list_free().
- Add missing unref().
- Fixed names in copyright notices.
- Change order of files in Makefile.am
