Re: [tracecompass-dev] API change: CallStack Analysis

So the change has been merged, it's harmless enough ;-) Thanks for the
prompt reviews.

Additional notes to implementers:

* If you extend the CallStackAnalysis or anything related, you'll need
to add a dependency to
'org.eclipse.tracecompass.analysis.profiling.[core|ui]' and update all
references to the now deprecated classes (they have the same name,
package, just change 'tmf' to 'analysis.profiling').

* The symbols have also been moved to the profiling plugins and the ones
in tmf.core/ui have been deprecated. Just changing the references should
be enough. If you extended the symbol provider extension point, you may
update the extension point name to

* In addition to the profiling plugins, you may need to add dependencies
to the following plugins if you extended the CallStackAnalysis:
org.eclipse.tracecompass.analysis.timing.core and
