f972197651 Promote libevent to lib/ level and fold ftp-proxy into its parent Makefile.
This allows us to use libevent for other application in the future.

For now libevent is still INTERNALLIB and no shared library is installed.

5608fd23c2 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.

864c53ead8 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.

3b3a8eb937 o Create directory sys/netpfil, where all packet filters should
reside, and move there ipfw(4) and pf(4).

o Move most modified parts of pf out of contrib.

Actual movements:

sys/contrib/pf/net/*.c		-> sys/netpfil/pf/
sys/contrib/pf/net/*.h		-> sys/net/
contrib/pf/pfctl/*.c		-> sbin/pfctl
contrib/pf/pfctl/*.h		-> sbin/pfctl
contrib/pf/pfctl/pfctl.8	-> sbin/pfctl
contrib/pf/pfctl/*.4		-> share/man/man4
contrib/pf/pfctl/*.5		-> share/man/man5

sys/netinet/ipfw		-> sys/netpfil/ipfw

The arguable movement is pf/net/*.h -> sys/net. There are
future plans to refactor pf includes, so I decided not to
break things twice.

Not modified bits of pf left in contrib: authpf, ftp-proxy,
tftp-proxy, pflogd.

The ipfw(4) movement is planned to be merged to stable/9,
to make head and stable match.

e0bfbfce79 Update packet filter (pf) code to OpenBSD 4.5.
You need to update userland (world and ports) tools
to be in sync with the kernel.
