sys: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

libc/syslog: fully deprecate and don't try to open "/dev/log"

The "/dev/log" socket existed in pre-FreeBSD times. Later it was
substituted to a compatibility symlink. The symlink creation was
deprecated in FreeBSD 10.2 and 9-STABLE.

sys: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Add static/const keywords to the arrays.

This theoretically allows a compiler to optimize (parts of) the array
away if unused.

While there, make the array size implicit and use a _Static_assert() to
ensure that the definition matches up with the number of elements in the
list.

A new jail(8) with a configuration file, to replace the work currently done

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

/* -> /*- for license, minor formatting changes

Protect against local flooder of /var/run/log. Do not loop forever in
syslog(3) if we are a priveleged program (sshd, su, etc.).

- Make syslogd open an additional socket /var/run/logpriv, with 0600
permissions.
- In libc, try to use this socket.
- Do not loop forever if we are using this socket (partial backout of 1.31)

o Merge <machine/ansi.h> and <machine/types.h> into a new header
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
macros, which are only MD because of gratuitous differences between
architectures.
o Change all headers to make use of this. This mainly involves
changing:
#ifdef _BSD_FOO_T_
typedef _BSD_FOO_T_ foo_t;
#undef _BSD_FOO_T_
#endif
to:
#ifndef _FOO_T_DECLARED
typedef __foo_t foo_t;
#define _FOO_T_DECLARED

syslog.h fails to compile with -Wwrite-strings

PR: 27492
Submitted by: Alexey V. Neyman <avn@any.ru>

Add the "LOG_CONSOLE" facility and tell syslogd to not log it on
console devices.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot). This is consistant with the other
BSD's who made this change quite some time ago. More commits to come.

$Id$ -> $FreeBSD$

This is the addition of a syslog(3) security.* top-level category. This
should be used from now on for anything security but not auth-related.
Included are updates for all relevant manpages and also to /etc files,
creating a new /var/log/security. Nothing in the system logs to
/var/log/security yet as of the time of this commit.

Added macros __printflike() and __scanflike() to <sys/cdefs.h>.
Use them to `make gcc -Wformat' check formats for all printf-like
and scanf-like functions in /usr/src except for the err()/warn()
family. err() isn't quite printf-like since its format arg can
legitimately be NULL. syslog() isn't quite printf-like, but gcc
already accepts %m, even for plain printf() when it shouldn't.

Since i've just touched <sys/syslog.h>, thereby causing a large part
of the system to be rebuilt anyway, this is a good time to introduce
LOG_NTP.

The reasoning for a separate facility is that xntpd can sometimes
cause exaggerative log message at high prioritites which are,
depending on your environment and available clock sources, not
necessarily as important as other LOG_DAEMON messages. However, they
used to clutter log files and system console in the existing setup.
Note that this situation could not be resolved using the !xntpd option
(think about it).

xntpd(8) is supposed to automatically pick up the change, it had
already all necessary #ifdef's.

The chosen value does, as far as my inquiries yielded, not clash with
any other operating system.

Shift the value for INTERNAL_MARK left by 3, as done for all other
facilities. This fixes the problems reported about syslogd not
recording marks correctly.

Add backward compatibility so that static executables built on
modern FreeBSD systems will syslog properly on older systems that
still name the logging socket "/dev/log". This includes pre-2.2
versions of FreeBSD as well as BSD/OS systems. If the connect to
"/var/run/log" fails, the function now tries to connect to
"/dev/log" as a fallback.

Remove an extraneous shift operation. The facility macros do already
shift the value.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

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.

Kill _OLD_PATH_LOG. It's not needed.

move the socket from /dev to /var/run by default
TRANSITIONALLY make syslog add a symlink..
I PROMISE I'll remove that as soon as I have the makefiles etc fixed as well.

Back out change of log from being in /var/run to back in /dev

syslog.h -> changed /dev/log to be /var/run/log (its a socket, not a device)
devfsext.h -> added prototype for dev_linkf();

Fix up some sloppy coding practices:

- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.
