e94c92cd48 SystemClock: elapsedRealtimeNano() should use clock_gettime() on Linux
We've removed the Android alarm driver from our supported kernels.
clock_gettime(CLOCK_BOOTTIME) has been a viable option since 2.6.39, so
there's no need for the legacy code path anymore.

We can use this on Linux hosts too, since no one should be building
Android on hosts with kernels that old.

6ed68cc412 Consistently use strerror in libutils.
It's easier for people to debug, and side-steps the problem that errno
values differ between architectures.

64289760a2 SystemClock: use clock_gettime() on devices without /dev/alarm
On devices with an up-to-date kernel, the back-in-time bug affecting
clock_gettime() has been fixed and it can safely be used as an
alternative to the ANDROID_ALARM_GET_TIME ioctl.  To ensure consistent
behavior on existing devices, make clock_gettime() a fallback for when
the alarm driver isn't available.

5cd118178e Disable timestamp logging.
The kernel problem has been fixed long time ago and the ad-hoc logging
mechanism is not thread safe and can flood the log with spurious
messages.
