8d2a9ce923 * dnsfilter: change DNS answer for host rules 
When matched by a host rule, return only the IP address specified in rule.
Respond with an empty IP list to another request type.

:: host -- return nothing to A, return :: to AAAA request
0.0.0.0 host -- return 0.0.0.0 to A, return nothing to AAAA request

b0cfd7228e - dnsfilter: fix post-install error "filter file not found" 
Right after installation we don't have the filter files downloaded.
While they are being downloaded, we replace them with an empty filter.

134d9275bb * use urlfilter v0.4.0 
Now we pass filtering rules to urlfilter as filer file names,
 rather than the list of rule strings.
(Note: user rules are still passed as the list of rule strings).

As a result, we don't store the contents of filter files in memory.
