Bug occurs when core dump destination in menuconfig is set to flash. When
programme crashes, xt_unhandled_exception or panicHandler will both trigger
commonErrorHandler. commonErrorHandler calls esp_core_dump_to_flash which
will attempt to use DPORT functions and hang due to trying to a stall and already
stalled processor (already stalled in xt_unhandled_exception and panicHandler).
Program will eventually be rebooted when wdt expires.
Added esp_dport_access_int_deinit after calls to haltOtherCore() so that DPORT
functions don't try to halt and already halted cpu hence preventing hang.
Fixes TW#12944 https://github.com/espressif/esp-idf/issues/646
Add new "make size_components" and "make size_files" targets for analysing makeup of the ELF file.
Plain "make size" output now looks like this:
Total sizes:
DRAM .data size: 11156 bytes
DRAM .bss size: 22304 bytes
Used static DRAM: 33460 bytes ( 294220 available, 10.2% used)
Used static IRAM: 80480 bytes ( 50592 available, 61.4% used)
Flash code: 421463 bytes
Flash rodata: 103824 bytes
Total image size:~ 616923 bytes (.bin may be padded larger)
Previously opendir("/data") would fail if filesystem with "data" prefix
was registered in VFS, while opendir("/data/") would succeed.
This change fixes handling for the former case and adds relevant tests.
Updated test case to include configASSERT cases (+1 squashed commits)

[871ec26f] Freertos:Bugfix uxTaskGetSystemState
Bug (github #12142) with uxTaskGetSystemState where
if called immediately after creating a bunch of tasks,
those tasks would be added twice into the TaskStatusArray.
Bug caused due to use old implementation using vTaskSuspendAll
which did not stop newly created task on other core from accessing the
read/waiting task lists whilst the list were being read by
uxTaskGetSystemState. Fixed bug by replacing vTaskSuspendAll
with taskENTER_CRITICAL and added test case for the bugfix
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.
