zmalloc

A very simple malloc checking library. Can be used as a source include as well.
The biggest advantage of this library is non intrusiveness. It does not rely on any platform specific features, should work everywhere.
How to use: use zalloc() and zfree() instead of the malloc and free calls. (Could be done by defines) Zmalloc will detect overwrites, freeing non freed items, not freeing items allocated. See the test_zmalloc on how to use it.
