Closed requested to merge mnowak/drop-testsummary.sh into main
testsummary.sh was not updated after build system rewrite to Autotools,
and needs to be fixed to produce test summary and core dump, assertion
failures, and ThreadSanitizer reports.
Given that all of this is provided by Autotools and run.sh already,
there's little use to
testsummary.sh script and should be dropped.
