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

Rename the "ip" package declaration to "ip-tiny" and let both "ip-tiny" and
"ip-full" provide the virtual "ip" package. This allows users to freely choose
the "ip" command variant while other packages can continue to depend on "ip"
without needing to enforce a specific variant.
Note that this commit does not add busybox as "ip" provider due to
the following reasons:
- The builtin Busybox ip applet cannot be added or removed at runtime
- Both "ip-tiny" and "ip-full" are able to install without file clashes even
if the busybox applet is enabled
- The system is preferring full "ip-tiny" and "ip-full" at runtime, even
if Busybox ip is still present.

The problem is that interfaces are specified at start as
command line arguments, making them unchange-able via reload.
That means, we have to move (since lldpd allows this) the
interfaces-match-pattern option to be in a config file and reload
the configuration.
It's either that, or do a 'restart'.
Since we're generating the lldpd.conf file, we'll have to
move the 'sysconfdir' of lldpd to /tmp, where the files will
get written ; this will prevent any unncessary flash writes.

Adds support in uci for configuring multiple dnsmasq instances via
multiple dnsmasq sections.
The uci sections host, boot, mac, tag, vendorclass, userclass,
circuitid, ... will refer to a dnsmasq instance via the instance
parameter defined in the section; if the instance parameter is
not specified backwards compatibility is preserved.
Start/Stopping a dnsmasq instance can be achieved by passing the
dnsmasq instance name as argument to start/stop via the init script.
Multiple dnsmasq instances is usefull in scenarios where you want to
bind a dnsmasq instance to an interface in order to isolate networks.

Add a partially random O= item to the certificate subject in order
to make the automatically generated certificates' subjects unique.
Firefox has problems when several self-signed certificates
with CA:true attribute and identical subjects have been
seen (and stored) by the browser. Reference to upstream bugs:
https://bugzilla.mozilla.org/show_bug.cgi?id=1147544https://bugzilla.mozilla.org/show_bug.cgi?id=1056341https://bugzilla.redhat.com/show_bug.cgi?id=1204670#c34
Certificates created by the OpenSSL one-liner fall into that category.
Avoid identical certificate subjects by including a new 'O=' item
with CommonName + a random part (8 chars). Example:
/CN=LEDE/O=LEDEb986be0b/L=Unknown/ST=Somewhere/C=ZZ
That ensures that the browser properly sees the accumulating
certificates as separate items and does not spend time
trying to form a trust chain from them.

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.

Support the usage of the OpenSSL command-line tool for generating
the SSL certificate for uhttpd. Traditionally 'px5g' based on
PolarSSL (or mbedTLS in LEDE), has been used for the creation.
uhttpd init script is enhanced by adding detection of an installed
openssl command-line binary (provided by 'openssl-util' package),
and if found, the tool is used for certificate generation.
Note: After this patch the script prefers to use the OpenSSL tool
if both it and px5g are installed.
This enables creating a truly OpenSSL-only version of LuCI
without dependency to PolarSSL/mbedTLS based px5g.
