Building without INET6 support was already possible. Now it's possible to
build ping with only INET6, or even with neither INET nor INET6.

Merge ping6 to ping

There is now a single ping binary, which chooses to use ICMP or ICMPv4
based on the -4 and -6 options, and the format of the address.

We remove IPSEC only in parts of the tree, and not others. RELEASE_CRUNCH to

need to disable IPSEC, one that hasn't shown up in the base system to date,
it can be re-added behind a WITHOUT_IPSEC build option.

Allow dhclient and ping to build WITHOUT_DYNAMICROOT

dhclient and ping normally use libcasper services. These are not
available in statically-linked binaries, so when WITHOUT_DYNAMICROOT is
set disable libcasper use, as with rescue builds. Also emit a warning
as it's undesirable to build this way.

Convert casperd(8) daemon to the libcasper.
After calling the cap_init(3) function Casper will fork from it's original
process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper
to new architecture.

Use CFLAGS, not COPTS, in the Makefile. bsd.prog.mk conveniently adds
COPTS towards the end of final CFLAGS so that it can be used to
