Merge remote-tracking branch 'origin/5.13' into dev
Conflicts:
tests/auto/widgets/itemviews/qheaderview/tst_qheaderview.cpp
Added tests/auto/testlib/selftests/expected_crashes_5.txt to work
round the output of the crashes test (which exercises UB, see
QTBUG-73903) being truncated on one test platform.
