Allow to specify the router advertisement mtu via the uci parameter
ra_mtu. In case the config parameter is not set the MTU is taken from
the interface as before.

In case maindhcp is set to disabled in global config one expect the DHCPv4
server not being started irrespective if the dhcpv4 interface config is set
to server.
Fix this by keeping maindhcp config apart from the legacy config parameter
as already documented in the README.

A ping for an IPv6 address not present on an interface will generate a
netlink neighbor message with as status fail; launching again an IPv6
ping on other proxy enabled interfaces will create a cascade effect of
netlink neighbor messages with as status fail which in its turn will
again trigger an IPv6 ping on proxy enabled interfaces ...

Create assignment for unknown identity association in rebind messages which is
equivalent to the handling of identity association for solicit/request messages.
However don't consider identity associations in rebind messages as a request so
that addresses/prefixes which are not apropriate for the link are returned with
lifetimes of 0.
This aligns with the behavior of the ISC DHCPv6 server.

Don't return anymore the link local IPv6 address as DNS IPv6 address
since different OS implementations (e.g. android, ...) cannot handle
a link local IPv6 address as DNS address.
IPv6 DNS address selection is reworked as follows :
-Consider all global/ULA IPv6 address having a valid lifetime
-Give preference to global/ULA IPv6 addresses being not deprecated
-Give preference to ULA IPv6 addresses over IPv6 global addresses
-Give preference to the IPv6 address with the longest preferred lifetime in
its selected category (ULA or global)
-If no global/ULA IPv6 address is present use the IPv6 link local address

Don't reset the final 32 bit IPv6 host suffix when storing the IPv6 addresses
in the interface structure. This will allow exact lookup aand return of IPv6
addresses stored in the interface structure when needed.

Make the code more logical by moving the IPv6 address dump logic into the
different protocol interface enable handlers so it's clear which protocols
require interface IPv6 address tracking.
At the same time restructure the IPv6 address dump logic so less IPv6 address
netlink dumps are created.

Don't set prefix valid lifetime to 0 in case the preferred lifetime
equals 0 and valid lifetime gets smaller than 7200.
In corner cases it leads to router lifetime being set although no
prefixes are announced with a valid lifetime different from 0.

Set dhcp leasetim to 43200 seconds for all interfaces independant
if dhcpv4 is enabled for an interface. Minimum allowed leasetime
is 60 seconds when parsing leastime configuration; this allows to

Add support for uci parameters ra_mininterval and ra_lifetime as described
in RFC4861 paragraph 6.2.1.
Variable ra_mininterval allows to configure the minimum interval time
between unsolicited router advertisement messages; default value is
200 seconds. The minimum allowed value is 4 seconds while the maximum
value is limited to 0.75 of the maximum interval time.
The calculation of the maximum interval time between unsolicited
router advertisement messages has been reworked. The default value is 600
seconds as specified in RFC4861; if the maximum interval time exceeds
0.33 * the minimal valid lifetime of all IPv6 prefixes it will be limited
to 0.33 * the minimal valid lifetime of all IPv6 prefixes
Variable ra_lifetime allows to configure the Router Lifetime field
in the router advertisement messages; the value is either 0 or a value
between the maximum interval time and 9000 seconds. If the router lifetime
is smaller than the RA maximum interval it will be set equal to the RA
maximum interval time.

Use libnl-tiny to construct and process netlink messages when
manipulating IPv6 routes and fetching IPv6 addresses.
This fixes lingering netlink error messages on the netlink socket
in case route deletion failed causing fetching of IPv6 addresses
to be aborted and odhcpd faultly assuming no IPv6 addresses being
present on the interface.
