With this property, users can control if this filter is 'on'

For some types of filters, they may need to react to status changing,
So here, we introduced status changing callback/notifier for filter class.
We will skip the disabled ('off') filter when delivering packets in net layer.

v2:
- Split the processing of buffer-filter into a new patch (Jason)
- Use 'status' instead of 'enabled' to store the filter state (Jason)
- Rename FilterDisable() callback to FilterStatusChanged(Jason)
