After the xEventGroupWaitBits in vProtLockInternalSpinUnlockWithWait there was an assertion about
pxYiledSpinLock being NULL, however when xEventGroupWaitBits returns, IRQs have been re-enabled
and so it is no longer safe to assert on the state which is protected by IRQs being disabled.

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.

* 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.
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.

* Xtensa: fix the coproc_area incorrect issue
foss-xtensa/amazon-freertos#2 mentioned a issue:
1.
In function pxPortInitialiseStack(StackType_t *pxTopOfStack....)
p = (uint32_t *)(((uint32_t) pxTopOfStack - XT_CP_SIZE) & ~0xf);
In function prvInitialiseNewTask (file: task.c)
pxTopOfStack = (pxStack + (ulStackDepth - 1)) & (~portBYTE_ALIGNMENT_MASK)
So the co-processor area is at
p = (uint32_t *)(((uint32_t)((pxStack + (ulStackDepth - 1)) & (~portBYTE_ALIGNMENT_MASK)) - XT_CP_SIZE) & ~0xf);
2.
In function vPortStoreTaskMPUSettings( .... , StackType_t pxBottomOfStack ...)
xMPUSettings->coproc_area = (StackType_t)((((uint32_t)(pxBottomOfStack + usStackDepth - 1)) - XT_CP_SIZE) & ~0xf);
pxBottomOfStack = pxStack
=> xMPUSettings->coproc_area = (StackType_t*)((((uint32_t)(pxStack+ ulStackDepth - 1)) - XT_CP_SIZE ) & ~0xf);
The p is coproc_area that should be equal to xMPUSettings->coproc_area.
For example, assume pxStack is 0xa0000000, ulStackDepth is 0x2000,
portBYTE_ALIGNMENT_MASK is 0x7f, XT_CP_SIZE is 0x100.
The p = (uint32_t)(((uint32_t)((pxStack + (ulStackDepth - 1)) & (~portBYTE_ALIGNMENT_MASK)) - XT_CP_SIZE) & ~0xf)
= 0xa0001e80
The xMPUSettings->coproc_area = (StackType_t)((((uint32_t)(pxStack+ usStackDepth - 1)) - XT_CP_SIZE ) & ~0xf)
= 0xa0001ef0
Obviously, the p is not equal to the xMPUSettings->coproc_area, which will cause context switching error.

In function pxPortInitialiseStack of port.c:
sp = ( StackType_t * ) ( ( ( UBaseType_t ) ( pxTopOfStack + 1 ) - XT_CP_SIZE - XT_STK_FRMSZ ) & ~0xf );
We assume XT_CP_SIZE is 0xE4, XT_STK_FRMSZ is 0xA0, pxTopOfStack is 0xA0000000, sp is 0x9FFFFE80.
From port.c, we know the frame->a1 as below:
frame->a1 = ( UBaseType_t ) sp + XT_STK_FRMSZ; /* physical top of stack frame */
So frame->a1 is 0x9FFFFF20. Therefore the interrupt stack frame range is 0x9FFFFE80 ~ 0x9FFFFF20.
The coproc_area is: p = ( uint32_t * ) ( ( ( uint32_t ) pxTopOfStack - XT_CP_SIZE ) & ~0xf );
So its value is 0x9FFFFF10. Obviously, the interrupt stack frame overlaps the coproc_area.

* Posix: Fix no task switching issue if a task ended
When the main function of a task exits, no task switching happened.
This is because all the remaining tasks are waiting on the condition
variable. The fix is to trigger a task switch and mark the exiting
task as "Dying" to be suspened and exited properly from the scheduler.

* Posix: Free Idle task resources after ending the scheduler
In case of using Posix simulator and ending the scheduler, it does
not free the resources allocated by the idle task. This
causes the memory checkers (Valgrind, Address Sanitizers, ..) to
complain.
* Posix: Free the condition variable memory in the correct place
In case of deleting a task from another task, the deletion happens
immediately and the thread is canceled but the memory allocated by
the task condition variable is not freed. This causes the memory
checkers (Valgrind, Address sanitizers, ..) to complain.
