7e2a3da643 esp32: Fix not the right time spent in a deep sleep
Before entering the deep sleep, the RTC and FRC counters are synchronized. Updating the boot_time.
Added a unit test for this case.
Fixed warnings for MULTIPLE_STAGES

6f529cbe64 newlib: Add adjtime - makes a gradual adjustment the system clock
This function speeds up or slows down the system clock in order to make a gradual adjustment. This ensures
 that the calendar time reported by the system clock is always monotonically increasing, which might not happen
 if you simply set the clock.

The delta argument specifies a relative adjustment to be made to the clock time. If negative, the system clock is
 slowed down for a while until it has lost this much elapsed time. If positive, the system clock is speeded up for a
 while.

If the olddelta argument is not a null pointer, the adjtime function returns information about any previous time
 adjustment that has not yet completed.

The return value is 0 on success and -1 on failure.

To stop the adjustement, call the function settimeofday(current_time).

bee1afaf6d time: rename time source option from FRC to "high-resolution timer"
libc time function now rely on esp_timer_get_time as the source of
high-resolution time, rather than FRC1 timer. Internally, on the ESP32
esp_timer implementation uses FRC2 timer.

- Change help text and labels in Kconfig to use "high-resolution timer"
  instead of FRC1. Keep existing Kconfig option name to be backwards
  compatible.
- Change references to "FRC1" in the source code to "FRC".

These functions were discarded but not provided in ROM.

Generated from commit 8ad0aa7d6 in newlib script repo. Didn't rebuild most of libc/libc_nano,
only appended the missing object files to the existing archives (should save some git churn).

Closes https://github.com/espressif/esp-idf/issues/1070

Note this is different to the other libc file-related syscalls, as there is no
reent structure involved.

project works, it's now mostly independent from the parent.

75d6fdf73c newlib locks: Fix _lock_init() & _lock_init_recursive() failing to initialise a lock
If scheduler was running, and lock was an automatic variable (ie stack-allocated) to be initialised by _lock_init*,
initialisation could be skipped if the lock variable was non-zero (and lock would be left invalid).

In other cases the lock is statically initialised to zero by __LOCK_INIT*

8ccb2a4990 esp32: make time monotonic across resets
Small changes to clock calibration value will cause increasing errors
the longer the device runs. Consider the case of deep sleep, assuming
that RTC counter is used for timekeeping:
- before sleep:
   time_before = rtc_counter * calibration_val
- after sleep:
   time_after = (rtc_counter + sleep_count) * (calibration_val + epsilon)
where 'epsilon' is a small estimation error of 'calibration_val'.
The apparent sleep duration thus will be:
time_after - time_before = sleep_count * (calibration_val + epsilon)
                           + rtc_counter * epsilon

Second term on the right hand side is the error in time difference
estimation, it is proportional to the total system runtime (rtc_counter).

To avoid this issue, this change makes RTC_SLOW_CLK calibration value
persistent across restarts. This allows the calibration value update to
be preformed, while keeping time after update same as before the update.

cc8af68244 syscalls: fix wraparound of RTC time
This change removes the erroneous cast to uint32_t (which caused time to
wrap around after 1 hour) and splits the multiplication into two terms
to remove the wraparound after 13 days.
