-----------
added "mdm dbg" and "alloc table" debugger commands.
This is a powerful procedure for memory leak detection without consuming
much memeory to log the history.
How to use.
----------
* Boot the target and give some timer so that PPP comes up.
* type "mem dbg" on the console. From here on all allocs (both
	malloc and calloc) are recorded with the caller.
* type "alloc table" to see the blocs allocated at any time
* typing "mem dbg" again will stop recording.
