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.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

- 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).

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.

ping(8)'s -a was mapped to -e, but -E was already taken in ping6 (old
option) so rename -e to -r.
Now:
ping -a => ping6 -r
ping -A => ping6 -R

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).

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.
