Disable an alarm use the same logic used to enable it: first try RTC_WKALM_SET
with the "enabled" flag set to false, if it fails fall back to RTC_AIE_OFF.

many rtc drivers don't implement the RTC_AIE_ON/OFF ioctls at all --
so if we never tried to enable the alarm interrupt, don't try to
disable it later.

Solaris lacks err, errx, warn and warnx. This also means the err.h header
doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.

Based on patch from
Piergiorgio Sartor <piergiorgio.sartor@nexgo.de>
at
https://bugzilla.redhat.com/show_bug.cgi?id=449115
Piergiorgio's note about S5:
> According to the ACPI specifications, chapter 4.7.2.4 "Real Time
> Clock Alarm", the wakeup from RTC, when supported, should work from
> *sleep* state S1-S3 and, optionally, from S4.
>
> Note 3 (same chapter) says that S5 is *not* a sleep state and should
> not be supported. Actually it also says that: "The OS will disable
> the RTC_EN bit prior to entering the G2/S5 or G3 states regardless."
>
> Nevertheless, on all PC supporting the RTC wakeup I tested, all were
> able to wake from S5.

This function is marked obsolete in POSIX.1-2001 and removed in
POSIX.1-2008.
Conditionally replaced with nanosleep().

People usually want to use pm-utils to suspend the system instead of
the raw kernel interface, so I added an option to just exit after
configuring the wakeup time.
Actually I think that all the suspend code should be removed from
rtcwake, since it does not really belong there.

rtcwake: Prefer RTC_WKALM_SET over RTC_ALM_SET, fixing bug with not
waking up with new RTCs. Also, return error if unable to set the alarm.

Writing "suspend" to /sys/power/state does nothing.
Even "man rtcwake" says that default should be "standby" :)

Timezone handling is broken in this version since it's always
passing UTC time into the kernel, even on systems where the
RTC uses the local timezone.
I think that bug must come from bugs in how the system used to
to originally develop this code handled the RTC timezone. Both
RTCs should have been kept in UTC ... but only one of them was.

Cleanups for rtcwake:
- Minor doc updates: highlight the framebuffer problem,
give correct history of this code
- Improve debug output
- Fix some linelength bugs
Note that this code predated the sysfs "wakealarm" mechanism, and
works around several now-fixed bugs in the kernel RTC framework.
Nowadays it would make sense to make this program use only the sysfs
interface to the RTC, using "since_epoch" instead of RTC_RD_TIME and
"wakealarm" instead of the four other ioctls. That could simplify
the mess involved in timezone handling.
