Functions
void	__heap_init (void)
	Initializes the default heap.
void	chHeapObjectInit (memory_heap_t *heapp, void *buf, size_t size)
	Initializes a memory heap from a static memory area.
void *	chHeapAllocAligned (memory_heap_t *heapp, size_t size, unsigned align)
	Allocates a block of memory from the heap by using the first-fit algorithm.
void	chHeapFree (void *p)
	Frees a previously allocated memory block.
size_t	chHeapStatus (memory_heap_t *heapp, size_t *totalp, size_t *largestp)
	Reports the heap status.
static void *	chHeapAlloc (memory_heap_t *heapp, size_t size)
	Allocates a block of memory from the heap by using the first-fit algorithm.
