* bpo-30764: Backport support.SuppressCrashReport Backport test.support.SuppressCrashReport context-manager from master. Drop the Windows implementation since it depends on msvcrt.CrtSetReportMode() which isn't available on Python 2.7. * bpo-30764: test_subprocess uses SuppressCrashReport (#2405) bpo-30764, bpo-29335: test_child_terminated_in_stopped_state() of test_subprocess now uses support.SuppressCrashReport() to prevent the creation of a core dump on FreeBSD. (cherry picked from commit cdee3f14f7f4c995e7eedb0bf6a67e260c739f7d)
