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
Interrupt registers.

Let the FreeRTOS IRQ handler properly store and restore the ICCIAR
register value around the vApplicationIRQHandler() call.

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.

This change removes the FreeRTOS System Calls (aka MPU wrappers) for the
following kernel APIs:
- xTaskCreateRestricted
- xTaskCreateRestrictedStatic
- vTaskAllocateMPURegions
A system call allows an unprivileged task to execute a kernel API which
is otherwise accessible to privileged software only. The above 3 APIs
can create a new task with a different MPU configuration or alter the
MPU configuration of an existing task. This an be (mis)used by an
unprivileged task to grant itself access to a region which it does not
have access to.
Removing the system calls for these APIs ensures that an unprivileged
task cannot execute this APIs. If an unprivileged task attempts to
execute any of these API, it will result in a Memory Fault.
