* 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
because both have already been used for another purposes in ping6(8).
* 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).

Revert changes in r269180. It could cause -c N option to enter an
infinite loop if no reply packet is received.

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.

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.

This also changes the semantics in case when we lose one of n packets.

This was needed during the IPSEC->FAST_IPSEC->IPSEC transition
period to not break the build after picking up netipsec header
files. Now that the FAST_IPSEC kernel option is gone and the
default is IPSEC again those defines are superfluous.

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.

(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.

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.
