Merge remote-tracking branch 'origin/5.7' into dev

Conflicts:
	qmake/library/qmakebuiltins.cpp
	qmake/library/qmakeevaluator.cpp
	qmake/library/qmakeevaluator.h
	qmake/project.h
QMakeEvaluator:
* evaluateConditional(): one side changed return type, the other
  changed a parameter type.
* split_value_list(): one side changed a parameter adjacent to where ...
* expandVariableReferences(): ... the other killed one overload and
  changed the survivor

	src/corelib/io/qlockfile_unix.cpp
One side changed a #if condition, the other moved NETBSD's part of
what it controlled.

	src/corelib/tools/qdatetime.cpp
One side fixed a reachable Q_UNREACHABLE in toMSecsSinceEpoch(), the
other moved it from the private class to the public one, in the midst
of the "short date-time" optimization, which confused diff entirely.
One side changed a QStringLiteral to QLatin1String, the other rewrote
adjoining code.

	src/network/kernel/qauthenticator.cpp
Both rewrote a line, equivalently; kept the dev version.

	src/platformsupport/fontdatabases/mac/qfontengine_coretext.mm
	src/platformsupport/fontdatabases/mac/qfontengine_coretext_p.h
One side changed #if-ery that the other removed.

	tools/configure/configureapp.cpp
One side added a check to -target parsing; the other killed -target.

	tests/auto/testlib/selftests/expected_cmptest.txt
	tests/auto/testlib/selftests/expected_cmptest.xml
	tests/auto/testlib/selftests/expected_cmptest.xunitxml
Regenerated using generate_expected_output.py
I note that quite a few other expected_* come out changed, now.

There was no git-conflict in
	src/widgets/kernel/qformlayout.cpp
but it didn't compile; one side removed some unused methods; the other
found uses for one of them.  Put FixedColumnMatrix<>::removeRow(int)
back for its new user.
