DIRDEPS_BUILD: Regenerate without local dependencies.

These are no longer needed after the recent 'beforebuild: depend' changes
and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports
skipping 'make depend'.

META MODE: Don't create .meta files when symlinking sources into the obj directory.

Tracking these leads to situations where meta mode will consider the
file to be out of date if /bin/sh or /bin/ln are newer than the source
file. There's no reason for meta mode to do this as make is already
handling the rebuild dependency fine.

Remove unneeded libutil dependency for sendmail.

It included libutil.h for setproctitle(3), which was moved from libutil to libc
in r65353 in 2000.

Add META_MODE support.

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.

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.

Reported by: kib

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.

Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to
get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.

Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang (disables -Werror)
- NO_WCAST_ALIGN.clang (disables -Wcast-align)
- NO_WFORMAT.clang (disables -Wformat and friends)
- CLANG_NO_IAS (disables integrated assembler)
- CLANG_OPT_SMALL (adds flags for extra small size optimizations)

As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf! For clang, use the following:

CC=clang
CXX=clang++
CPP=clang-cpp

Use sendmail's version of vacation. It is command line and database
compatible with the old version but includes new functionality and bug fixes.

Since it is not part of the NO_SENDMAIL make.conf option, libsmdb and

Null commit to reflect that the previous commit added warnings for
previously unreported malloc() failures, and changed the exit status
for those failures to encourage MTA retries.

* Add a command-line option to enable debugging mode, which sends error
messages to stderr instead of syslog.

* Fix manpage with respect to diagnostics.

Reported by: rfg@monkeys.com (Ronald F. Guilmette)

Calls one or more of malloc(), warn(), err(), syslog(), execlp() or
execvp() in the child branch of a vfork(). Changed to use fork()
instead.

Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

Add const to copyright string. Hide sccsid string.

Many places in the code NULL is used in integer context, where
plain 0 should be used. This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

Even better fix: use close(fileno(mfp)); to close unneded descriptor
and not clobber memory by fclose().

Better fix: return vfork() again, but remove clobbering fclose()
and use _exit() instead of exit()

Replace vfork() by fork(), vfork() usage is totally bogus in this context.
This program don't bother to do even minimal vfork() support as per vfork(2)
manpage required.

compare return value from getopt against -1 rather than EOF, per the final

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Removed stray DPADD.

Various cleanups:

. prototyped and staticized the internal functions while i was here,
. made the thing -Wall clean,
. fixed an error that causes the recipient name to be matched only
for the first characters, as opposed to a full name (wonder why i'm
concerned? Well, one of my login IDs is `j', and i've noticed that
vacation has been sending out replies to all mailing list messages
that had a jkh@ or jmb@ in it :),
. introduced an option -l to list the contents of the database; mucho
useful if you've got (too) many mailing list messages in your inbox
and wanna make sure you don't miss the `important' mails.

Correct a bunch of man page cross references and generally
try and silence "manck".

ncurses, rpc, and some of the gnu stuff are still a big mess, however.

Correct some manual page cross reference errors. E.g. su is a section

and only fixes man pages in manual section one.

Delete bogus referneces to timezone code internal header file `tzfile.h',
