Heap improvements (#462)
* Heap improvements

This commit makes the following improvements:

1. Add a check to heap_2 to track if a memory block is allocated to the
   application or not. The MSB of the size field is used for this
   purpose. The same check already exists in heap_4 and heap_5. This
   check prevents against double free.

2. Add a new flag configHEAP_CLEAR_MEMORY_ON_FREE to heap_2, heap_4 and
   heap_5. The application writer can set it to 1 in their
   FreeRTOSConfig.h to ensure that a block of memory allocated using
   pvPortMalloc is cleared (i.e. set to zero) when it is freed using
   vPortFree. If left undefined, configHEAP_CLEAR_MEMORY_ON_FREE
   defaults to 0 for backward compatibility. We recommend setting
   configHEAP_CLEAR_MEMORY_ON_FREE to 1 for better security.

3. Add a new API pvPortCalloc to heap_2, heap_4 and heap_5. This API
   has the following signature:
   void * pvPortCalloc( size_t xNum, size_t xSize );
   It allocates memory for an array of xNum objects each of which is of
   xSize and initializes all bytes in the allocated storage to zero. If
   allocation succeeds, it returns a pointer to the lowest byte in the
   allocated memory block. On failure, it returns a null pointer.

Update uncrustify configuration to 0.69 (#445)
The configuration was updated using

    uncrustify -c .github/uncrustify.cfg -o .github/uncrustify.cfg --update-config-with-doc

to align with the actually used uncrustify version used, i.e., all
configuration is now explicitly set (and no longer implicit).

The files that are common to all ports ("portable/MemMang*" and
"portable/Common/mpu_wrappers.c" are now also autoformatted.

Place privileged symbols correctly (#84)
Some of the privileged symbols were not being placed in their respective
sections. This commit addresses those and places them in
privileged_functions or privileged_data section.
