8a16b7a18f General further adoption of SPDX licensing ID tags.
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.

fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

b021de9cd7 Add -x waittime and -X timeout options for feature parity. These are
equivalent to -W and -t options of ping(8).  Different letters are used

0ecaa7ed05 Fix a problem that reply packets are not received when -i T option is set
and (T < RTT).

- Use select(2) for timeout instead of interval timer. Remove poll(2) support.
- Use sigaction(2) instead of signal(3).
- Exit in SIGINT handler when two signals are received and doing reverse DNS
  lookup as ping(8) does.
- Remove redundant variables used for getaddrinfo(3).

dc91b5609a When interval is set to very small value with limited amount of packets,
ping6(8) would quit before the remote side gets a chance to respond.

Solve this by resetting the itimer when we have reached the maximum packet
number have reached, but let the other handling to continue.

5df1b6b57e Use FF02:0:0:0:0:2:FF00::/104 prefix for IPv6 Node Information Group
Address.  Although KAME implementation used FF02:0:0:0:0:2::/96 based on
older versions of draft-ietf-ipngwg-icmp-name-lookup, it has been changed
in RFC 4620.

The kernel always joins the /104-prefixed address, and additionally does
/96-prefixed one only when net.inet6.icmp6.nodeinfo_oldmcprefix=1.
The default value of the sysctl is 1.

ping6(8) -N flag now uses /104-prefixed one.  When this flag is specified
twice, it uses /96-prefixed one instead.

115737b173 Change the exit status for 0 and 2 to be the same as with ping(1)
and be usable in scripts, etc.

This also changes the semantics in case when we lose one of n packets.
In that case, before we exited by SIG, now we exit with return(0).

ad092d18d7 Correct two issues in ping6:
1. The static buffer that ping6(8) uses to hold the control data
   it gets from recvmsg(2) is too small in some cases.
2. When it prints the extra header information it doesn't do
   any checking to make sure the data it's printing is within
   the bounds of the supplied buffer.

Fix this by:
o Increasing the buffer to hold extra headers to 10240 bytes (the minimum
  according to RFC3542 sec. 20.1) and allocate it dynamically.
o In verbose mode, specify a warning if any control data from recvmsg(2)
  was truncated because the buffer was too small.
o When printing the extra headers make sure not to overrun the buffer
  boundaries.

f95d46333d Switch Advanced Sockets API for IPv6 from RFC2292 to RFC3542
(aka RFC2292bis).  Though I believe this commit doesn't break
backward compatibility againt existing binaries, it breaks
backward compatibility of API.
Now, the applications which use Advanced Sockets API such as
telnet, ping6, mld6query and traceroute6 use RFC3542 API.

3111be41c2 Quote from a Problem Report:
The output format specifier for the round-trip time in ping6 should be
changed to %.3f instead of %g since %g doesn't accurately represent the
precision of the number being output. In particular, %g truncates trailing
zeroes. 0.01 ms does not mean the same thing as 0.010 ms. Although they
are numerically identical, they do not have the same precision.

  - ip6po_m member of struct ip6_pktopts is no longer used.  But, it
