callstack: Add incubated LttngUstCallStackAnalysis
Bring Incubator's LTTng-UST CallStack analysis as the new mainlined one. Add com.google.common.base to the UI dependencies, which was reported as missing at runtime otherwise, upon exiting. [Added] o.e.t.i.a.callstack.core.LttngUstCallStackAnalysis Change-Id: I6e190aa1e85906e99c307bf61fc5062d9a69d9f7 Signed-off-by: Marco Miller <marco.miller@ericsson.com> Reviewed-on: https://git.eclipse.org/r/c/tracecompass/org.eclipse.tracecompass/+/199641 Tested-by: Trace Compass Bot <tracecompass-bot@eclipse.org> Tested-by: Bernd Hufmann <bernd.hufmann@ericsson.com> Reviewed-by: Bernd Hufmann <bernd.hufmann@ericsson.com>
