There are some invalid condition checks in rtc.c, when rtc_file is
missing, it should not consider that as a error and return, otherwise,
it can lead to the case that time_set wont be called at all.
With this fix, when both RTC and file restore fail, it will fall back
to call time_set(NULL) and restore time from rtc_timestamp, this
ensures the OS has a valid time at the very first boot.

These variables really belong in conf.c. Relocate and move external
decls. from finit.h -> conf.h to simplify linking of other programs.

With the relocation of several functions, including inline functions,
from helpers to util, we no longer need to include log.h. Which is a
good thing, since any subsystem that needs logging should explicitly
include log.h

Introduced to work-around systems with broken RTCs, it also introduced a
dormant bug in Finit, triggered at shutdown on some systems. The call
to dlclose() removed the memory to the rtc_timer which libuev later then
referenced.
Fixes#429

These plugins signal success and failure directly to the console, the
user should inspect syslog for more information.
This change is a follow-up to 340cae4, where kernel logs of LOG_ERR and
higher are allowed to log directly to the console. Since syslogd has
not been started before these plugins, the log messages would otherwise
leak to the console.

In 42ef3d3c, for v4.4-rc1, support for setting a custom RTC restore date
was introduced. Unfortunately the configure script was wrong and caused
config.h to contain
#define RTC_TIMESTAMP_CUSTOM "$rtc_date"
instead of
#define RTC_TIMESTAMP_CUSTOM "2023-04-10 14:35:42"
Furthermore, the error handling for strptime() was wrong, so the restore
date was always reverted to the default.
This patch fixes both issues and extends the DATE of --with-rtc-date to
also include seconds.

This patch introduces a new configure option --with-rtc-file=FILE. When
enabled the RTC plugin detects missing RTC device and falls back to save
and restore system time from a file instead. When --with-rtc-file is
used without an argument the default file is /var/lib/misc/rtc, but the
feature itself is disabled by default.
The usefulness of this feature may not be obvious at first, but some
systems are equipped with an RTC that resets to a random date at power
on. This can be really bad in the case the date is far in the future,
because an NTP sync would then cause time skips backwards, which shows
up in logs and causes a whole lot of pain in alarm systems.
The solution is to disable the RTC driver or device tree node, and when
Finit starts up, the RTC plugin detects a the device node and instead
restores time from the last save game. Meaning time will always only
move forwards.
NOTE: when Finit is built --with-rtc-file we always save to disk, but
only restore from the "save game" if restoring from RTC fails.
If the system has no RTC we always restore from disk.
As an added bonus, this change also makes sure to periodically
sync also the RTC with the system clock. Useful for systems
that do not run an NTP client.

Due to an unfortunate name clash with the DirectFB project LiTE, the
libite (-lite) project had to change its header namespace from
lite/*.h -> libite/*.h
This patch adds support for the new namepace in Finit, triggered by the
define _LIBITE_LITE, from the .pc file read by pkg-config. This should
only be needed on systems that install libite without the compatibility
symlink lite -> libite/ in the staging include directory.

These plugins should not run in rescue mode, because the system may be
in a very bad state and we do not want to make the situation any worse
than it already is.
Essentially, only services in rescue.conf should run in rescue mode.

This patch sets the TZ variable to a sane default, UTC. Fixing, at
