1c461df70a 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.

2d6c175d9b 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.

2b94c053d1 Fix traceroute applet on the FreeBSD
This patch addressing 2 issues:

1. Replacing source/dest with uh_sport/uh_dport. It seems that uh_* members are
   defined on both Linux and BSD, so no #ifdef here
2. Use SOL_IPV6 instead of SOL_RAW on the FreeBSD to fix IPV6_CHECKSUM setsockopt
