- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Since clang 3.2 now has an option to suppress warnings about implicitly
promoted K&R parameters, remove the workarounds added for sendmail
components in r228558.

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

In usr.bin/vacation/Makefile, fix a typo in the comment about clang
warnings.

MFC after: 1 week

Unfortunately, clang gives warnings about sendmail code that cannot be
turned off yet. Since this is contrib code, and we don't really care
about the warnings, just turn make them non-fatal for now.

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

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

Remove kludges intended to support src trees with partial obj trees.

Discussed with: ru

Remove MAINTAINER= lines from individual Makefiles in favor of the
MAINTAINER file (which already had entries for sendmail).

Update build infrastructure for sendmail 8.12.

Remove NO_WERRORs and WARNS=n's. To be revisited after GCC3.

Protect this from the coming WARNS=2 default.

Add a MAINTAINER= line so people know who to blame

Fix man page installation
Style fixes

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
libsmutil should always be built for vacation's sake.

getopt and friends are declared in <unistd.h>
getopt returns -1 not EOF.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

Add a messy example of how to get debug-mode error messages written to
a file in the user's home directory.

Requested by: hoek

Postpone call to usage() until after all options are processed so that
the -d debugging option produces consistent behaviour.

Please forgive me, it's my first day on the block. Forgot to mention:

PR: 11987

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.

PR: Loosely related to bin/8252

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.

Stop parsing args before user supplied to argument in sendmail.
Submitted by: Oliver Friedrichs <oliver@silence.secnet.com>

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
posix standard on the topic.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

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
one man page, not section eight. This is the first round of such changes
and only fixes man pages in manual section one.

Delete bogus referneces to timezone code internal header file `tzfile.h',
which is no longer bogusly installed in /usr/include.
