Update to current HEAD in order to drop automatic generation of per-zone
NOTRACK rules.
The NOTRACK rules used to provide a little performance improvement but the
later introduction of the netfilter conntrack cache made those rules largely
unnecessary. Additionally, those rules caused various issues which broke
stateful firewalling in some scenarios.

Update to latest Git head in order to import several fixes and enhancements.
- Disable drop invalid by default (FS#73, FS#154)
Instead of dropping packets with conntrack state INVALID, only allow streams
with explicit NEW or UNTRACKED conntrack state.
This change gives user defined rules the chance to accept traffic like ICMPv6
multicast which would be filtered away by the very early ctstate INVALID drop
rule otherwise.
The old behaviour can be restored by explicitely setting "drop_invalid" to 1
in the global firewall config section.
- Fix re-initialization of loadable iptables extensions on musl (FS#31)
Since musl does not implement actual dlclose() semantics, it is impossible to
re-run initializers on subsequent dlopen() calls.
The firewall3 executable now intercepts the extension registration calls
instead in order to be able to re-call them when needed.
This also allowed us to switch to libxtables' builtin extension loader as a
positive side-effect.
- Fix masquerade rules for multiple negated IP addresses (FS#248)
When building MASQUERADE rules for zones which specify multiple negated
addresses in masq_src or masq_dest, emit -j RETURN rules which jump out of
the masquerading chain instead of creating multiple rules with inverted "-s"
arguments.
- Tag own rules using comments
Instead of relying on the nonstandard xt_id match, use the xt_comment match
to mark own rules. Existing comments are prefixed with "!fw3: " while
uncommented rules are marked with a sole "!fw3" string.
This allows removing the xt_id match entirely in a later commit.
- Make missing ubus connection nonfatal
Technically, firewall3 is able to operate without ubus just fine as long as
the zones are declared using "option device" or "option subnet" instead of
"option network" so do not abort execution if ubus could not be connected or
of no network namespace is exported in ubus.
This allows running firewall3 on ordinary Linux systems.
- Fix conntrack requirement detection for indirectly connected zones
The current code fails to apply the conntrack requirement flag recursively to
zones, leading to stray NOTRACK rules which break conntrack based traffic
policing.
Change the implementation to iteratively reapply the conntrack fixup logic
until no more zones had been changed in order to ensure that all directly and
indirectly connected zones receive the conntrack requirement flag.
- Add support for iptables 1.6.x
Adds support for the xtables version 11 api in order to allow building
against iptables 1.6.x

This option, defined by RFC3442, allows a DHCP server to send static
routes to a client. But the client has to request this option
explicitely.
Static routes are useful when the gateway configured by DHCP cannot be
in the same subnet as the client. This happens, for instance, when
using DHCP to hand out addresses in /32 subnets.
A new configuration option "classlessroute" is available, allowing
users to disable this feature (the option defaults to true).
Other DHCP clients already request this option by default (dhcpcd, for
instance, and possibly Windows). If a DHCP server does not support
this option, it will simply ignore it.

This adds IPv6 support to qos-scripts for both tc/qdisc and the
iptables classification rules. The tc/qdisc part is accomplished
by removing "protocol ip" from the tc command line, causing the
rule to be applied to all protocols. The iptables part is
accomplished by adding each rule using both iptables and ip6tables.
This patch is based on previous work by Ilkka Ollakka and
Dominique Martinet.
