clock: add clock_resynchronize and use subseconds RTC
...
Add clock_resynchronize for better synchronization of CLOCK_REALTIME and CLOCK_MONOTONIC to match RTC after resume from low-power state.
Add up_rtc_getdatetime_with_subseconds under CONFIG_ARCH_HAVE_RTC_SUBSECONDS to allow initializing (and resynchronizing) system clock with subseconds accuracy RTC.

Fix 64-bit clock-related constant value evaluation for AVR compiler
...
This may be specific for Atmel AVR8 toolchain compiler.
The problem is that despite of being 8-bit architecture
avr-gcc supports uint64_t, but the following code
uint64_t value = 10000 * 1000;
produces a wrong negative value in the final code (tested
both with and without optimization).
The work-around is simple:
uint64_t value = 10000 * 1000L;
The code is a reduced part from sched/signal/sig_timedwait.c where
waitticks64 is calculated using NSEC_PER_TICK. This one is defined
as USEC_PER_TICK * NSEC_PER_USEC which leads to the example above.

When reading the system timer, don't read a struct timespec, convert it to a fake tick count, then back to a timespec. Remove CLOCK_ACTIVETIME.. it is non-standard, unused, and gets in the way of changes like this

Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion. Also, the tickless OS no appears fully functional and passes the OS test on the simulator with no errors

Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK. This gives more options for system timers in general, but more importantly, let's us realize higher resolution for the case of CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new interger overvflow problems
