Memory Usage View improvements

Browse Source 
* Add special handling for unknown sizes, to avoid possible overflows
when converting to C types.

* Fetch any available memory usage data when opening the view, to refresh
it on opening if a map file is already present

* Display properly exceptions that occur when parsing map files, making sure
they appear in the Messages view when running the testsuite.

* Add another automatic test.

For eng/ide/gnatstudio#402
