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".

239ac0e17b newlib: Add strptime(), qsort_r(), nanf() to libc & libc_nano
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).

48d9d507aa newlib: Remove fcntl() implementation from libc
Allows fcntl() implementation in vfs to be used.

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.

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.

6353bc40d7 Add support for 32k XTAL as RTC_SLOW_CLK source
- RTC_CNTL_SLOWCLK_FREQ define is removed; rtc_clk_slow_freq_get_hz
  function can be used instead to get an approximate RTC_SLOW_CLK
  frequency

- Clock calibration is performed at startup. The value is saved and used
  for timekeeping and when entering deep sleep.

- When using the 32k XTAL, startup code will wait for the oscillator to
  start up. This can be possibly optimized by starting a separate task
  to wait for oscillator startup, and performing clock switch in that
  task.

- Fix a bug that 32k XTAL would be disabled in rtc_clk_init.

- Fix a rounding error in rtc_clk_cal, which caused systematic frequency
  error.

- Fix an overflow bug which caused rtc_clk_cal to timeout early if the
  slow_clk_cycles argument would exceed certain value

- Improve 32k XTAL oscillator startup time by introducing bootstrapping
  code, which uses internal pullup/pulldown resistors on 32K_N/32K_P
  pins to set better initial conditions for the oscillator.

90c43ea95e newlib: fix register used for DPORT/RTC bug workaround
While there was no register at DR_REG_FRC_TIMER_BASE + 0x60, due to
peripheral address space wraparound this write actually affected one of
FRC2 registers, which is used by WiFi stack to implement legacy
ets_timer APIs.
This change uses FRC_TIMER_LOAD_REG(0) instead, which can be set to
known value safely.

8c25a0fd9d time: workaround for FRC_TIMER_INT_REG write issue
In some cases (when RTC register reads are performed from the APP CPU), a write to FRC_TIMER_INT_REG may be lost on the bus.
Writing to another DPORT register immediately before or after that works around the issue.
We write one dummy value to an address which doesn’t have any register associated with it.

c47cc63489 newlib: change definition of assert for release builds
One common pattern of using assert function looks as follows:
    int ret = do_foo();
    assert(ret == 0);   // which reads as: “do_foo should never fail here, by design”
The problem with such code is that if ‘assert’ is removed by the preprocessor in release build,
variable ret is no longer used, and the compiler issues a warning about this.
Changing assert definition in the way done here make the variable used, from language syntax perspective.
Semantically, the variable is still unused at run time (as sizeof can be evaluated at compile time), so the compiler
can optimize things away if possible.
