Several C programs fail to include the headers declaring all the
functions they call, resulting in warnings or errors.
After this, memfd_test.c is still missing some function declarations
but can't easily get them because of a conflict between
<linux/fcntl.h> and <sys/fcntl.h>.

Calling ioctl(..., RTC_UIE_ON, ...) without CONFIG_RTC_INTF_DEV_UIE_EMUL
either ends in rtc_update_irq_enable if rtc->uie_unsupported is true
or in __rtc_set_alarm in the if (!rtc->ops->set_alarm) branch. In both
cases the return value is -EINVAL. So check for that one instead of
ENOTTY.

It was reported that the alarmtimer-suspend test hangs on older
systems that don't support _ALARM clockids.
This is due to the fact that we don't check if the timer_create
fails, and thus when we suspend, the system will not programatically
resume.
Fix this by checking the timer_create call for errors.

On the hardware I have, resume latency from an alarm is often
2-3 seconds (with a fair amount of variability due to the RTC's
single second granularity). Having four seconds be the pass/fail
bar is maybe a little too tight, so extend this to 5 seconds.

When testing on some hardware, waiting only a second before
re-triggering suspend can keep TCP connections from re-establishing
which after a number of cycles can cause TCP connections to close
while the test is running.
So extend the delay between suspend calls to 3 seconds to let
the connections stay alive.

The set-timer-lat test fails when testing CLOCK_BOOTTIME_ALARM
or CLOCK_REALTIME_ALARM when the user isn't running as root or
with CAP_WAKE_ALARM.
So this patch improves the error checking so we report the
issue more clearly and continue rather then reporting a failure.

For the default run_timers target, the timers tests takes the
majority of kselftests runtime.
So this patch reduces the default runtime for inconsistentcy-check
and set-timer-lat, which reduced the runtime almost in half.

Adds the set-2038 test which sets the time to near-edge cases
like the start and end of the 32 bit epoch and checks that
time behaves properly. There is also a dangerous mode, which
lets the clock roll over past 2038 on 32bit systems, which
on some older kernels will cause system hangs.

This adds my clock skew estimation test from the timetest suite.
It measures the drift between CLOCK_MONOTONIC and CLOCK_MONOTONIC_RAW
and compares it with the current frequency value from adjtimex.
It sometimes can trigger false failures when ntpd isn't in a
steady state, but its a useful too when doing adjtimex testing.

The posix_timers.c test has a loop that tries to keep it in
kernel space, repeatedly calling brk(). However, it doesn't
check the return value, which causes warnings.
This patch adds a err value which captures the return value
and modifies the test so it will quit if a failure occurs.

Add some initial basic tests on a few posix timers interface such as
setitimer() and timer_settime().
These simply check that expiration happens in a reasonable timeframe after
expected elapsed clock time (user time, user + system time, real time,
...).
This is helpful for finding basic breakages while hacking
on this subsystem.
