Emit the highlighted signal if the model changes.

The bug is that the connection to emit that signal can be made
obsolete if the connection is made too early and the model is replaced.
In the bug report, the connection is made by calling view() early (thereby
causing the creation of a view and a QItemSelectionModel which operates on
the built-in QItemSelectionModel, and then connecting to that
QItemSelectionModel), and then when QComboBox::setModel() is called later
the built-in view creates a new QItemSelectionModel for it. The bug was
that that new QItemSelectionModel is not connected to. This patch fixes that
bug.

In the new (inlined, internal) constructor, both the MSB bits in the

low that the two MSB bits should never be set, the compiler can

Logging: mark qt_assert()/qt_assert_x()/qFatal() as nothrow

These functions are not supposed to return, not even by exception.
qt_message() _can_ throw, but we're fine with the compiler calling
std::terminate() then, since the backtrace will still include the
assertion location.

This behaviour is ensured by a new macro, QT_TERMINATE_ON_EXCEPTION,
which expands to something like
   try { expr; } catch(...) { std::terminate(); }
if the compiler doesn't support Q_DECL_NOEXCEPT (but maybe
Q_DECL_NOTHROW), and to something like just
   expr;
otherwise (including in the QT_NO_EXCEPTION case).

The real macro preserves scopes in all cases, and aims
to work even if <exception> isn't included in the TU it's used in,
so is a little bit more complex than that.

where the sender object is in a different thread at transition setup

Therefore: Bite the sour grape and traverse all the machine's
transitions when the machine is being started, registering those
signal transitions whose sender objects are in other threads.

This will increase the machine's startup time (proportional to the

meaning we don't have to document weird restrictions regarding the
