Fix hostname not being reported as "-" in the DHCP statefile in case

In case infinite leasetime is assigned to a non static DHCPv4/v6 lease
override the infinite lifetime of the lease when either a DHCPv4/v6
decline or release is received.

This reverts commit 5f425ed1e5f92397e27ec4f44820b6ef677b8134.
Both dnsmasq and odhcpd use the ignore option. This is fine for normal
operation, but it breaks DHCPv6 relay when dnsmasq is disabled on the
wan interface.

It does not make sense to scan the entire routing table if the decision
will be overridden afterwards.
This makes it possible to use odhcpd on a router with full IPv6 BGP
table, by setting ra_default to 2. Without this change, odhcpd is
constantly busy reading /proc/net/ipv6_route, and doesn't respond to
router solicitations in time.

Set bound flag for DHCPv4 and DHCPv6 assignments when the IPv6/IPv4 address
is leased to a client.
This will prevent the printing of leases and hostname/IPv4/IPv6 address
combinations in the state file for for which the IPv4/6 address has not
been assigned.
Also this will fix the printing of assignments which have been declined
by the clients

In case multiple dhcp uci sections are configured and one section contains
RA config while the other section does not; the RA interface config of the
first section will be overwritten by the second section.
Fix this by setting the default values for ra_management and ndp_proxy_routing
uci parameters when the interface is created and by removing the overwrite check

The valid_until parameter which is set to 0 for static DHCPv6
assignments was overwritten depending on the received DHCPv6 message
which turned the assignment into having a finite lifetime and thus not
static anymore.
Fix this by checking if the valid_until parameter holds infinite
lifetime before updating it.

Fix assignment of static DHCPv6 leases which was broken
by commit 6c3bc0141dacc88992583d6f2cdc8a360df7422d.
At the same time fix lifetime check of existing assignments
having a finite lifetime
Fixes FS#309

The "ignore" option is correctly loaded. Actually observe it as
documented.

Currently the loglevel is hardcoded to LOG_WARNING, even though there is
debug log messages. Allow setting the loglevel via cli option.
Include basic help text because we're adding command line options.

Add support for DHCPv4 clients proposing a leasetime;
proposed leasetime will be accepted if it does not
exceed either the pool or configured lease leastime.
Further rework the duplicated leasetime logic which
was in place.

Keep the valid_until assignment parameter in sync with the
leasetime assigned to the DHCP client when handling DHCP
request message.
This guarantees the contents of the ubus dhcp ipv4leases valid
parameter is in sync with the client leasetime

Add support for infinite leasetime value; this can be done by
specifying "infinite" as leasetime value which is similar to
dnsmasq infinite leasetime support.
Specifying "infinite" as leasetime is valid for both the host
and dhcp uci sections.
A DHCPv4/DHCPv6 assignment is now considered infinite if valid_unil
holds the value 0.

Drop pointless syslog. The single line just doubles the amount of lines
logged to syslog without adding any value.

When a prefix lifetime was greater than UINT16_MAX, we would advertise a
shorter router lifetime (even potentially 0). Saturate instead.
