* DEBUG_MEMORY:
*
* DEBUG_MEMORY replaces the allocator with a collect and debug
* shell to the libc allocator.
* DEBUG_MEMORY should only be activated when debugging
* libxml i.e. if libxml has been configured with --with-debug-mem too.

* The XML memory wrapper support 4 basic overloadable functions.
* xmlFreeFunc:
* @mem: an already allocated block of memory
*
* Signature for a free() implementation.
d xmlFreeFunc s * based(######typedef######)
d procptr
* xmlMallocFunc:
* @size: the size requested in bytes
*
* Signature for a malloc() implementation.
*
* Returns a pointer to the newly allocated block or NULL in case of error.
d xmlMallocFunc s * based(######typedef######)
d procptr
* xmlReallocFunc:
* @mem: an already allocated block of memory
* @size: the new size requested in bytes
*
* Signature for a realloc() implementation.
*
* Returns a pointer to the newly reallocated block or NULL in case of error.
d xmlReallocFunc s * based(######typedef######)
d procptr
* xmlStrdupFunc:
* @str: a zero terminated string
*
* Signature for an strdup() implementation.
*
* Returns the copy of the string or NULL in case of error.
d xmlStrdupFunc s * based(######typedef######)
d procptr
* The 5 interfaces used for all memory handling within libxml.
* Since indirect calls are only supported via a based prototype,
* storage is accessed via functions.
