qubes.py now places rules for each domain in a separate key under
/local/domain/fw_XID/qubes_iptables_domainrules/
plus the header in /local/domain/fw_XID/qubes_iptables_header.
/local/domain/fw_XID/qubes_iptables is now just a trigger.
So, if iptables-restore fails dues to e.g. error resolving a domain name
in a rules for a domain, then only this domain will not get connectivity,
others will work fine.
Modify VM packages to:
- do not conflicts
- starts services if its VM type need it
Added core-proxyvm (firewall) and core-commonvm (common parts) packages.
