For one, an attacker can try to overload us by just opening and immediately
closing tons of connections - reduce our work to the minimum for this case.

udhcpc[6]: untangle "timeout" and "remaining lease"; reduce min lease to 30 seconds
...
This allows to fix a problem that we wait for renew replies
for up to half the lease (!!!) if they never come.
Make it so that lease of 60 seconds is not "rounded up" to 120 seconds -
set lower "sanity limit" to 30 seconds.
After 3 failed renew attempts, switch to rebind.
After this change, we can have more flexible choice of when to do
the first renew - does not need to be equal to lease / 2.

udhcpc: ignore zero-length DHCP options
...
Discovered that the DHCP server on a TrendNet router (unknown model)
provides a zero-length option 12 (Host Name) in the DHCP ACK message. This
has the effect of causing udhcpc to drop the rest of the options, including
option 51 (IP Address Lease Time), 3 (Router), and 6 (Domain Name Server),
most importantly leaving the OpenWrt device with no default gateway.
The TrendNet behavior violates RFC 2132, which in Section 3.14 declares that
option 12 has a minimum length of 1 octet. It is perhaps not a cosmic coincidence
that I found this behavior on Pi Day.
This patch allows zero length options without bailing out, by simply skipping them.

ntpd: decrease INITIAL_SAMPLES from 4 to 3
...
This reduces initial traffic to NTP servers when a lot of devices boot at once.
Log inspection tells me we agressively burst-poll servers about 5 times
at startup, even though we usually already update clock after second replies.
INITIAL_SAMPLES can probably be even lower, e.g. 2, but let's be conservative
when changing this stuff.

udhcp: bind to device even for ucast packets
...
There are cases where binding to source IP and
destination IP is insufficient to guarantee sane
xmit netdev.
One case where this can fail is when
route-matching netdev carrier is down (cable
unplugged, wifi disconnected), or the netdev is
admin down. Then all the IP based bindings (bind()
+ connect()) will seemingly succeed but the actual
packet can go out through a default gw path.
Depending on the network this happens on
it can create issues or false alarms. It can
also leak some subnet info across networks that
shouldn't be routed.
As such better be safe than sorry and bind to a
netdev to be sure it's used for xmit.
