- vTaskPreemptionDisable()/vTaskPreemptionEnable() are no longer available in
single-core builds.
- xTaskIncrementTick() calls must now be wrapped by critical section
- Minimal Idle Task renamed to Passive Idle Task
- Port critical section APIs updated
This commit replaces the use of portNUM_PROCESSORS and configNUM_CORES
macros in all of ESP-IDF. These macros are needed to realize an SMP
scenario by fetching the number of active cores FreeRTOS is running on.
Instead, a new Kconfig option, CONFIG_FREERTOS_NUMBER_OF_CORES, has been
added as a proxy for the FreeRTOS config option, configNUMBER_OF_CORES.
This new commit is now used to realize an SMP scenario in various places
in ESP-IDF.
[Sudeep Mohanty: Added new Kconfig option CONFIG_FREERTOS_NUMBER_OF_CORES]

This commit moves xTaskIncrementTickOtherCores() to freertos_tasks_c_additions.h
and freertos_idf_additions_priv.h (as API is private). This reduces the code
differences cmpared to upstream FreeRTOS.
This commit refactors port_systick.c so that all ports (RISC-V vs Xtensa) of
all FreeRTOS implementations (IDF vs Amazon SMP FreeRTOS) use the same set of
tick interrupt functions. Thus, these funcitons are now common:
- vPortSetupTimer() to setup the tick interrupt's timer
- xPortSysTickHandler() that is called on each tick interrupt
