undo SSP damage from -Wsystem-headers

A little more restructuring so that we don't need mutex stuff in syslog_ss.

Split syslog.c to:

- syslog_ss.c *_ss api functions (don't use stdio, time)
- syslog.c: *syslog* non _ss api functions (use stdio, time)
- xsyslog.c> common guts.

The motivation for this is not to drag in stdio/locale/floating point/time
for every binary, since syslog_ss() is used in __stack_check_fail() for SSP.

Use strerror(3) instead of strerror_r(3) and an arbitary buffer size which could be too small.

make more descriptors that we open as close-on-exec

take care of the signal safe syslog calls which are not exposed.

add more locking (when we read and write fields)

PR/47055: David Holland: Remove static hostname and store the hostname in
syslog_data. Initialize hostname before it is used. While here, add a version
to syslog_data.

PR/45989: Martin Husemann: lint invocation does include -w only on i386

- turn lint -w for all the platforms after fixing the lint warnings.
- add _DIAGASSERTS() for casts that would assign values to types that
  would not fit.
- change types, add casts
- change into ansii prototypes
- turn on _DIAGNOSTIC for libc (during current, to be eliminated for release
  builds)

approved by core@

close on exec fixes:
- open + fcntl -> open O_CLOEXEC
- configuration database file descriptors that can stay open are now opened
  fopen(db, "re")

PR/43300: Takahiro Kambe: LOG_PID and LOG_CONSOLE printed syslogp messages
to the console/stderr since the syslogp conversion.

merge christos-time_t

merge with head.

Martin says:

I had added a getaddrinfo()/getnameinfo() lookup to obtain an FQDN even
if gethostname() would return only the local part of the hostname.
I did not really consider that many systems do not have FQDNs and more
importantly that the calls introduce a high latency (timeout) when DNS
is not available.

On the other hand I do not (or no longer) think that using a non-FQDN is
such a big problem here. Those users/admins that do collect logs from
different hosts and want an FQDN should notice the problem quickly
enough and can easily fix it by correctly setting their hostname.

time_t changes

file syslog.c was added on branch christos-time_t on 2008-11-08 21:45:38 +0000

Invert the test for the return value of getaddrinfo(), because that's what
is actually meant there, to do nothing when the name doesn't resolve to an
address.

fix compile error.

Import syslogd SoC project by Martin Schuette:
	- new syslog protocol api syslogp(3) that supports structured data
	  and draft-rfc timestamps
	- reliable tcp connections with queueing
	- encrypted connections

appease lint: warning: assignment in conditional context [159]

- vsyslog_r only closes if it opened
- maintain opened properly
- preserve the tag (from OpenBSD)

PR/38539: Ed Ravin: libc/gen/syslog.c always logs to console if LOG_CONS is set.
While here:
1. Don't loop forever, handle closing and opening the log after each send.
2. Release the lock later, after we've possibly printed to the console.

Don't expose _ss functions for 4.0. Requested by core.

weak for syslog_ss

use FD_CLOEXEC instead of 1.

- verify that the log file is usable, otherwise re-open it.
- if the file is re-opened, clear the connected flag.
- don't check that the file is opened before connecting, because the
  file will be opened then.

need to negate before masking; from abp.

add async-signal-safe versions: syslog_ss and vsyslog_ss
multithread-safe syslog_r and vsyslog_r are not async-signal-safe.

don't use strerror_r in the re-entrant case.

add _r functions for syslog from OpenBSD

WARNS=4

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

Merge the nathanw_sa branch.

Catch up to -current.

__STDC__ is always defined on NetBSD.

Pull up revision 1.27 (requested by atatat):
  Add a single retry into syslog(), to cope with a restarted syslogd,
  so that log messages don't get lost.  Most useful for long-running
  programs.

Catch up to -current.

_REENT -> _REENTRANT

Build a single retry into syslog() so that if someone restarted
syslogd after we called openlog(), we don't just to lose until we call
openlog() again.  Or get restarted.  This is good for long running
processes that use syslog(), like sendmail, postfix, named, etc.

convert from __progname to getprogname()

Be consistent with argument types vs. prototype; use _BSD_VA_LIST_ as
the argument, instead of va_list. Might not make a difference on most
ports, depending on toolchain/MD typedefs. Does make a difference on sparc64,
where it wouldn't compile otherwise.

Delint.
Remove trailing ; from uses of __weak_alias().  The macro inserts this if
needed.

Fix unaligned access lint warning.

Use SUN_LEN, not sizeof.

Use a struct sockaddr_un, so that the new _PATH_LOG actually fits into it.

Protect syslog descriptor state with a mutex.  TODO: cleanup handling for
cancellation points.

delint

Use localtime_r() rather than localtime(); removes a potential source of
surprise for the application.

Add some braces to make egcs happy.

Delint (partially).

use AF_LOCAL instead of AF_UNIX

remove obsolete register declarations

merge/update to lite-2

import lite-2

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore.  The library will use those
names internally.  Weak aliases are used to provide the original names
to the API.

This is only the first part of this change.  It is most of the functions
which are implemented in C for all NetBSD ports.  Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.

Clean up a little, and fix a fencepost error.

Don't overflow fixed sized buffers.  Parts of this patch come from
Perry Metzger, Charles Hannum and Paul Kranenburg.

#include "namespace.h"

don't explicitly declare strerror --- <string.h> already provides a prototype

fix operator precedence error (pr 951 from Ted Lemon)

fix up some RCS Id's i botched.

merge with 4.4-Lite, keeping local changes.  clean up Ids

from lite, with minor name rearrangement to fit.

Change C library functions to use strchr() and strrchr() instead of index()
and rindex().  This will allow (strict {ANSI, POSIX, XOPEN}) applications
to redefine index() and rindex() without effecting the library internals.

Declare rcsid strings so they are stored in text segment.

Add even more RCS frobs.
