Debug Malloc (Dmalloc) Library Release Notes

Mostly a bug fix release but I made some changes to the dmalloc_examine arguments so a minor release it is.

Expanded the dmalloc_examine function to be able to return more information about a pointer. This breaks the API for this function unfortunately.
Improved the statistics output to the logfile.
Added the tsecs perl script to the contrib/ subdirectory. The tsecs script converts time in epoch-seconds (which is by default written into the logfile) into a readable time/date string.

The check-lists debug token has been removed since it is no longer valid with the new memory admin structures.

None.

The arguments to dmalloc_examine were changed to allow this function to return more information about a pointer. This was done to help the test program probe various information about a pointer.
Greatly expanded the dmalloc_t program to test specific bugs as they were found. Hope this will become a good regression test utility.

The check-lists debug token has been removed since it is no longer valid with the new memory admin structures.

Fixed the FREED_POINTER_DELAY functionality where pointers that have just been freed can not be reused until a certain number of malloc calls have been made.
Fixed the never-reuse feature where pointers will never be reused once freed.
Fixed a problem where a call to dmalloc_log_changed would wipe out allocate table information.
Found and fixed a problem where the last-used mark was not being set properly.
Found and fixed a bad problem where the leaked memory was not being reported correctly. Very bad.
