* Add CMake build
Allows to build and link FreeRTOS using CMake build system.
From top-level project it looks like this:
set(FREERTOS_PORT_GCC_ARM_CM4F ON)
set(FREERTOS_CONFIG_FILE_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} CACHE STRING "")
add_subdirectory(third_party/FreeRTOS-Kernel)
Where FREERTOS_PORT_GCC_ARM_CM4F is FreeRTOS port name.
freertos is target name, which can be used in target_link_libraries()
* Add feature to set custom heap source file
Example how to set it from top-level project:
set(FREERTOS_HEAP ${CMAKE_CURRENT_LIST_DIR}/path_to/my_heap.c CACHE STRING "")
* Set cmake_minimum_required to 3.15
* Fail build when FREERTOS_CONFIG_FILE_DIRECTORY not set
* Rename library to freertos_kernel
* Rework FREERTOS_PORT option to act as combobox
* Use freertos_kernel_port cmake target
* Split port sources multiline

* fix alignment exception for ullPortInterruptNesting.
While loading (LDR X5, ullPortInterruptNestingConst) the ullPortInterruptNesting
variable, the program control seems to be stuck and there is no abort or stack
trace observed (as there is no exception handler is installed to catch unaligned
access exception).
Program control moves forward, if one just declares this varible to be 2 bytes
aligned but then varible is not updated properly.
One of my colleague, pointed out that issue is due to the fact that
ullPortInterruptNesting must be at 8 bytes aligned address but since
"vApplicationIRQHandler" (that has 4 bytes of address) is sitting between
two 8 bytes aligned addresses that forces ullPortInterruptNesting to be at
4 byte aligned address, causing all sort of mess.
It works on QEMU (on ARM64) as it is, since there is no such check for
unaligned access but on real hardware it is prohibited.
Workaround to this problem is, either we skip 4 byets (using .align 4) after
vApplicationIRQHandler declaration or declare it the end of all declarations.
This commit does the latter one.

* RP2040: malloc needs to be thread safe for FreeRTOS whether both cores are used or not
* RP2040: CMake file had broken left over test code
* RP2040: portIS_FREE_RTOS_CORE() returned an incorrect value prior to scheduler init when the application was compiled without multicore support
* RP2040: Bad initialization code was causing IRQs to get disabled before main() was called when using non static allocation
This commit introduces a new config
configALLOW_UNPRIVILEGED_CRITICAL_SECTIONS which enables developers to
prevent critical sections from unprivileged tasks. It defaults to 1 for
backward compatibility. Application should set it to 0 to disable
critical sections from unprivileged tasks.

There's already a portYIELD_FROM_ISR() macro that calls vPortYield() which wraps the FromISR code.
It doesn't appear that vPortYieldFromISR() is intended to be publicly accessible in this port so
I've marked it as private to silence the warning.
event_create() also got flagged due to missing void in prototype.

Mention that FreeRTOS_IRQ_Handler should not be used for FIQs and the
reason for assuming Group 1 for Interrupt Acknowledge and End Of

The secure side context management code now checks that the secure
context being saved or restored belongs to the task being switched-out
or switched-in respectively.

This commit improves ARMv8-M security by pre-allocating secure-side task
context structures and changing how tasks reference a secure-side
context structure when calling a secure function. The new configuration
constant secureconfigMAX_SECURE_CONTEXTS sets the number of secure
context structures to pre-allocate. secureconfigMAX_SECURE_CONTEXTS
defaults to 8 if left undefined.

* Use cast to fix warnings.
* Remove all empty definitions of portCLEAN_UP_TCB( pxTCB ) and
portALLOCATE_SECURE_CONTEXT( ulSecureStackSize ) from ports.
When these are undefined, the default empty definition is defined
in FreeRTOS.h.
The difference between this port and portable/GCC/ARM_CA53_64_BIT is
that this port uses System Register interface to access CPU interface
while the other one uses Memory-mapped interface.

* Introduce configRUN_TIME_COUNTER_TYPE which enables developers to define the type used to hold run time statistic counters. Defaults to uint32_t for backward compatibility. #define configRUN_TIME_COUNTER_TYPE to a type (for example, uint64_t) in FreeRTOSConfig.h to override the default.
Introduce ulTaskGetIdleRunTimePercent() to complement the pre-existing ulTaskGetIdleRunTimeCounter(). Whereas the pre-existing function returns the raw run time counter value, the new function returns the percentage of the entire run time consumed by the idle task. Note the amount of idle time is only a good measure of the slack time in a system if there are no other tasks executing at the idle priority, tickless
idle is not used, and configIDLE_SHOULD_YIELD is set to 0.
* Add ultaskgetidleruntimepercent to lexicon.txt.
* Update History file.
Add the MPU version of ulTaskGetIdleRunTimePercent().
* Update include/FreeRTOS.h to correct comment as per aggarg@ suggestion.
* Fix alignment in mpu_wrappers.h.
Commit changes to mpu_prototypes.h which were missed from the original commit.
event_wait_timed() was ignoring a timeout of 1000 ms.
Presumably this is because pthread_cond_timedwait() only
considers tv_nsec less than one second.
Convert the timeout in miliseconds to second and nanosecond
components to fix this.
