-** Implementation of the os level dynamic memory allocation interface in terms
-** of the standard malloc(), realloc() and free() found in many operating
-** systems. No rocket science here.
-**
-** There are two versions of these four functions here. The version
-** implemented here is only used if memory-management or memory-debugging is
-** enabled. This version allocates an extra 8-bytes at the beginning of each
-** block and stores the size of the allocation there.
-**
-** If neither memory-management or debugging is enabled, the second
-** set of implementations is used instead.
