Added ASSERT() macro

src/core/heap.c

 #include "memsizes.h"

-#define ASSERT(...)
-
 struct heap_block {
 	size_t size;
 	char data[0];
 	physaddr_t addr;

-	ASSERT ( ! ( align & ( align - 1 ) ) );

 	addr = ( ( ( heap_ptr - size ) & ~( align - 1 ) )
 		 - sizeof ( struct heap_block ) );

+	ASSERT ( ptr == phys_to_virt ( heap_ptr + sizeof ( size_t ) ) );
 	
 	block = ( struct heap_block * )
 		( ptr - offsetof ( struct heap_block, data ) );
