9d539f9fbd sysklogd: add timestamp option to ignore message timestamps
Some syslog producers provide inconsistent timestamps, so provide an option
to ignore the message timestamps and always locally timestamp.  In order to
implement this, invert the valid-timestamp check, but only use the timestamp
if this option is not enabled.

This is in line with what what other syslogd implementations do:

From sysklogd syslogd.c:
 * Sun Nov  7 12:28:47 CET 2004: Martin Schulze <joey@infodrom.org>
 *      Discard any timestamp information found in received syslog
 *      messages.  This will affect local messages sent from a
 *      different timezone.

rsyslog's imuxsock module similary has an (enabled by default)
IgnoreTimestamp option:

ae57fcad5d syslogd: make "reopen log file every second" logic work for multiple logs
Move last_log_time from a single global to *each logFile_t*
so that we can actually apply the logic to every log-file
in multi-file configurations, rather than working only
for the first file written in each 1-second interval
and then leaving the others connected to possibly wrong files.

As suggested by Mike. No bloat-o-meter difference, but a bit nicer to look at.
We cannot convert the call to log_to_shmem() as it checks for G.shbuf outside
the function, and G.shbuf is only available when IPC support is enabled.

cd776cf967 syslogd: add option to log to Linux kernel printk buffer
Why invent our own shared memory circular buffer when the kernel has a
perfectly fine one already?

This can be used as a smaller/simpler alternative to the syslogd IPC support
(as IPC shmem/klogd/logread aren't needed), while also allowing centralised
logging of everything (kernel messages, userspace bootup and syslog)
when used together with ttyprintk.

Notice that kernel 3.5+ is needed to store syslog facility in printk buffer,
otherwise only the priority is stored.

bloat-o-meter compared to IPC+klogd+logread:

12677acf0a CONFIG_PID_FILE_PATH: new configuration option for pidfile paths
We set a default path for the directory where pidfiles are create
when FEATURE_PIDFILE is selected.  The default has no effect on
applets which must specify a pidfile path on the command line to
run, and it can be overridden by applets which optionally allow
the user to specify the pidfile path.

We also add pidfile write/remove support for klogd, ntpd and watchdog.
For syslogd, we add a missing remove_pidfile() for better cleanup
on daemon exit.

8de2e42201 syslogd: work around rename() not renaming hardlinks to themselves
Function log_locally() within the syslogd can potentially lock up when
restarting the daemon after a power loss in case the unplanned shutdown hit the
rename operation during logfile rotation.

While POSIX requires the rename operation to be atomic, many file systems such
as JFFS2 implement the rename operation in 2 steps by linking the new name
followed by unlinking the original name. In case of a power loss during the
rename the system can end up with /var/log/messages and /var/log/messages.0
being 2 hard links to the same file.

When the syslog daemon restarts in such a situation it will rediscover the need
to rotate the log files, however, POSIX also requires that rename does nothing
and reports success in case oldpath and newpath are existing hard links to the
same file. Looping through reopen: by (O_CREAT | O_APPEND), the daemon
eternally reopens the same file without succeeding to rotate.
