On 32bits platforms "struct timeval" or "time_t" are using u32 to code the
date, this cause tools like "date" or "hwclock" failed even before setting
the RTC device if the date is superior to year 2038 (or 2106).

To avoid this problem I add one RTC test file which directly use RTC ioctl
to set and read RTC time and alarm values.
rtctest_setdate allow to set any date/time given in the command line.

On this version 2 I add check of problematics years in rtctest like suggest
by Alexandre.

Finally that had allowed me to test and fix rtc-st-lpc driver.

Hi Thomas/John,

I can take the first two patches in this series through linux-kselftest
with your or John's Ack. Please review and let me know one way or the
other.

Well, I'm the maintainer for rtctest.c and I'll make sure to also be the
one for rtctest_setdate.c.

The third one is a rtc driver patch. Please let me know how do you want
to handle this series soon we can get this into 4.13-rc1.

I'll take the three patches but I still have comment I didn't have time
to give yet.
