On the receive socket, recvmsg() and poll()/select() is called.
Therefore, CAP_EVENT is needed in addition to CAP_RECV..
While there, check the socket for readbility before calling recvmsg().

The revision D25604 capsicumize traceroute6. For UDP the send socket was
changed from SOCK_DGRAM to SOCK_RAW and thus the UDP checksum need be
calculated by application itself other than the kernel.
outpacket is filled with zeros by line 707, thus the first round the UDP
checksum is correct. But subsequent rounds outudp->uh_sum will be left
with garbage.

- Always use distinct sockets for send and recv
- Limit rights on the recv socket
For ICMP6 we were using the same socket for both send and receive, and
we limited rights on the socket such that it's impossible to receive
anything.

This with the previous patch I committed makes traceroute6/traceroute
compile fine when libcasper isn't enabled.
This complains strongly with unused variables and such when compiled
with gcc-6 on mips32.

Fix some style issues as well. Leave -Wno-cast-aligned set for now, as
most of the warnings come casts of CMSG_DATA(), which does provide
sufficient alignment in practice.

It was turned on unconditionally in r121472 (in 2003) and has been on ever
since. The old alternative code has bitrotted. Reap the dead code.

SHUTDOWN-ACK chunks, possibly bundled with a PAD chunk.
Packets with INIT chunks more likely pass through firewalls. Therefore,
use them when possible.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
* Ensure that the datalen always describes the length after the IPv6
header consistently, not matter which protocol us used for probes..
* Document that the default length is 20, not 12.
* Don't send inormation in probe packets which is not needed or
even checked when the responses are processed.
* Address CID 978587.
This is mainly a cleanup preparing the addition of SCTP and TCP
as possible probe packet protocols.
