Enhance MALLOC_DEBUG CLI commands.

Browse Source 
* Fixed CLI "memory show allocations" misspelling of anomalies option.
The command will still accept the original misspelling.

* Miscellaneous tweaks to CLI "memory show allocations" command output
format.

* Made CLI "memory show summary" summarize by line number instead of by
function if a filename is given.

* Made CLI "memory show summary" sort its output by filename or
function-name/line-number depending upon request.

* Miscellaneous tweaks to CLI "memory show summary" command output format.
