Many libraries allow the user to pass in replacements for malloc(), free(), and realloc(). This helps the user debug memory allocation, and use special-purpose allocators as needed.

    I've done a patch for this. Instead of using malloc(), free(), realloc(), calloc(), and strdup(), libevent now uses event_malloc(), event_free(), and so on. By default, these are the same as the stdc versions, but the library user can override them by calling event_sent_mem_functions and passing in a malloc/realloc/free tuple.

    I'll probably commit this tomorrow if there are no objections.

    (I'd attach the patch, but sourceforge is being funny.)
