pkgbase: Move rc scripts and related files to their own packages

It doesn't need to be in runtime and might help people who want to
experiment with other rc system or don't use one (like in small
embedded mfsroot).

Explicitly add more files to the 'runtime' package.

- Revert r277670 (#include order is required for fparseln)
- Remove unnecessary CFLAGS+= -I now that make is no longer required to make
rcorder build

Remove the unnecessary glob

Fix CFLAGS+=-DDEBUG by using the right header for libutil (libutil.h, not
util.h)

Convert sbin/ to LIBADD
Reduce overlinking

Revert r267233 for now. PIE support needs to be reworked.

1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
where it never would work anyhow, such as csu or loader. This suggests
there may be better ways of adding support to the tree. Many of these
cases can be fixed such that -fPIE will work but there is really no
reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
really building libraries but have been using bsd.prog.mk because the code
is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
been needed.

We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

In preparation for ASLR [1] support add WITH_PIE to support building with -fPIE.

This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.

Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]

Mark known build failures as NO_PIE for now.

The only known runtime failure was rtld.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Switch the default WARNS level for sbin/ to 6.

- Import the HEAD csup code which is the basis for the cvsmode work.

Crank WARNS up to 6, just because we can.

style.Makefile(5):
Use WARNS?= instead of WARNS=.

Fixed style of DPADD and LDADD assignments as per style.Makefile(5).

Reduce the -I's as we don't need them all.

FreeBSDize the NetBSD Makefile so that this compiles.

Import the NetBSD 1.5 RC system.

Note that `rc' and `rc.shutdown' could not be imported because we already
have files with those names.
