FreeRTOS MPU: Add privileged execute never MPU attribute
A new MPU region attribute Privileged eXecute Never (PXN)
is introduced in Armv8.1-M architecture, where if an MPU
region has PXN attribute set and the processor attempts
to execute the code inside with privileged level,
the Memory Management Fault exception would be triggered,
with IACCVIOL bit in MemManage Fault State Register set
to 1. The PXN feature allows privileged software to ensure
specific application tasks (threads) to execute in
unprivileged level only.

Use _GNU_SOURCE macro instead of __USE_GNU and define it before
including portmacro.h. The reason is that portmacro.h includes limits.h
which in-turn includes features.h - this results in __USE_GNU getting
incorrectly undefined.

Earlier the code was suspending the current thread after calling
vTaskSwitchContext. This left a gap where the current thread could
access incorrect pxCurrentTCB after it was changed by
vTaskSwitchContext.
This commit addresses the problem by suspending the current thread
before calling vTaskSwitchContext.
It was reported here - https://github.com/FreeRTOS/FreeRTOS-Kernel/issues/1054.

* Add configUSE_TASK_FPU_SUPPORT to AARCH64 port
NEON SIMD is required by standard AARCH64 and its registers are
frequently utilized by standard functions such as memcpy().
This means that even simple tasks that do not use any floating point
arithmetics may still alter the contents of the FPU registers.
For this reason it makes sense to add support for
configUSE_TASK_FPU_SUPPORT to be able to enforce FPU register saving and
restoring globally.
The implementation was largely adopted from the ARM_CA9 port. However,
the FPU registers must be placed on the stack before the critical
nesting count to match the AARCH64 portASM.S.
Add GCC/ARM_CM0/mpu_wrappers_v2_asm.c and GCC/ARM_CM0/portasm.c as source files to 'freertos_kernel_port' library.
This fixes the FREERTOS_PORT "GCC_ARM_CM0" CMake configuration.

Currently in Armv8-M GCC/ArmClang ports, constant pool is used to
define literals needed for `ldr` instructions. However, those
constant pools are defined with `.align 4` which increases code size.
Instead of defining the constant pool with `.align 4`, let the
compiler hanlde the constant pool and the required alignment.

The difference between a stream buffer and a stream batching buffer is when
a task performs read on a non-empty buffer:
- The task reading from a non-empty stream buffer returns immediately
regardless of the amount of data in the buffer.
- The task reading from a non-empty steam batching buffer blocks until the
amount of data in the buffer exceeds the trigger level or the block time
expires.
Update alignment in ARM_CR5 port.
This is the same patch as 553caa18ce
provided by Richard Barry for issue #426 (ARM_CA9).

* 64bit TickType_t is supported on Windows port.(MSVC and MinGW)
Especially it is introduced for 64bit compiler.(x64 platform on MSVC and MinGW-w64)
* Unnecessary compiler warning for the cast operation is disabled locally.(MinGW-w64 only)
* Modify the condition for ignoring compiler warning for the cast operation.
Before modification: Compiler warning was ignored only on MinGW64
After modification: Compiler warning is ignored on MinGW32 and MinGW64
Reason of modification: The cast warning here is unavoidable not only on MinGW64 but also on MinGW32.
"__GNUC__" macro is used because MSVC does not recognize this #pragma directive.
* Fix small bugs
* Cast sizeof to BaseType_t
* Test removing assert to fix UT
* Revert change to tasks.c
Since configIDLE_TASK_NAME must be defined as a string according to
the documentation, the macro will always be NULL terminated. Which
means that the check `if( cIdleName[ xIdleTaskNameIndex ] == ( char ) 0x00 )`
will catch the end of string.
* Update coverity config; Add coverity version; Update pvPortMalloc declaration to match the definitions.
* Add port files to sed command
* Remove warnings about unused parameters in port code
