Adopt SRCTOP in usr.bin

Prefer ${SRCTOP}/foo over ${.CURDIR}/../../foo and ${SRCTOP}/usr.bin/foo
over ${.CURDIR}/../foo for paths in Makefiles.

Silence on: arch@ (twice)

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Convert to usr.bin/ 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.

Replace all uses of libncurses and libtermcap with their wide character
variants. This allows usable file system images (i.e. those with both a
shell and an editor) to be created with only one copy of the curses library.

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.

When building picobsd, define WITHOUT_OPENSSL and WITHOUT_KERBEROS and
remove the now-redundant checks for RELEASE_CRUNCH. This originally
was defined for building smaller sysinstall images, but was later also
used by picobsd builds for a similar purpose. Now that we've moved
away from sysinstall, picobsd is the only remaining consumer of this
interface. Adding these two options reduces the RELEASE_CRUNCH
special cases in the tree by half.

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Fix conflicts after heimdal-1.1 import and add build infrastructure. Import
all non-style changes made by heimdal to our own libgssapi.

Remove the -DFAST_IPSEC from Makefiles again.

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.

Stop enforcing dependencies between MK_* options at Makefile level.
All the dependencies are satisfied now in <bsd.own.mk>.

Respect MK_INET6_SUPPORT.
Move INET6 out of the RELEASE_CRUNCH conditional block
because it saves as little as 2% of the binary size and
IPv6 is rather popular today. (Some other binaries, e.g.,
telnetd, include INET6 for RELEASE_CRUNCH already.)

NOCRYPT -> NO_CRYPT

Join the 21st century: Cryptography is no longer an optional component
of releases. The -DNOCRYPT build option still exists for anyone who
really wants to build non-cryptographic binaries, but the "crypto"
release distribution is now part of "base", and anyone installing from a
release will get cryptographic binaries.

Approved by: re (scottl), markm
Discussed on: freebsd-current, in late April 2004

Make sure that a "make release" (more accurately the bit that makes
the crunched binary) get a non-cryptographic telnet. This is overkill
in that it covers stuff that is not normally used in a crunched binary.

Ensure that for the cryptographic instances of *telnet*, the "crypto"
distribution is used. This only affects release-building.

Test correct macro for "without crypto" option(s).

Very big makeover in the way telnet, telnetd and libtelnet are built.

Previously, there were two copies of telnet; a non-crypto version
that lived in the usual places, and a crypto version that lived in
crypto/telnet/. The latter was built in a broken manner somewhat akin
to other "contribified" sources. This meant that there were 4 telnets
competing with each other at build time - KerberosIV, Kerberos5,
plain-old-secure and base. KerberosIV is no longer in the running, but
the other three took it in turns to jump all over each other during a
"make buildworld".

As the crypto issue has been clarified, and crypto _calls_ are not
a problem, crypto/telnet has been repo-copied to contrib/telnet,
and with this commit, all telnets are now "contribified". The contrib
path was chosen to not destroy history in the repository, and differs
from other contrib/ entries in that it may be worked on as "normal"
BSD code. There is no dangerous crypto in these sources, only a
very weak system less strong than enigma(1).

Kerberos5 telnet and Secure telnet are now selected by using the usual
macros in /etc/make.conf, and the build process is unsurprising and
less treacherous.

Remove WARNS?=2 and -Wall. WARNS?=2 is going to be the default.

Diff-reduce WRT src/secure/*telnet*/Makefile.

Also, add an "unifdef:" target, so that the telnet sources can
be remade from the crypto sources in src/crypto/telnet.

Code merge and diff reduction between this and crypto telnet.

Also remove useless AUTHENTICATION code. We have never compiled this
here, and it is doubtful that it even works without crypto.

libtelnet.a is gone; add a special hack for `make release' fixit floppy.

Bye-bye /usr/lib/libtelnet.a. This should fix ``make release'' brokeness.

Nearly missed this one. Turn off -DTERMCAP otherwise it defines a bunch

Oh foo. I should a) learn to read. b) learn to think. :-)
Telnet has nothing to do with this, it's telnetd and telnetd
doesn't use KLUDGELINEMODE so that theory is washed up. Anyway,
back out previous commit and slink away with red face.

Remove -DKLUDGELINEMODE again; it's breaking things and Paul T. says
it's a bug anyway.
