Previously the code for isColumnSelected and isRowSelected differed
slightly, in how unselectable indexes would be treated.
This made isColumnSelected return false for a column, which mixed
unselectable indexes and selected indexes. Thus in some situations,
the user could not deselect a column via a QTableView header.
By copying the isRowSelected code to isColumnSelected, rows and
columns behave identical.

There had been a fake declaration for qEnvironmentVariable() in qglobal.h
thaqt was only visible to QDoc. It was removed in favor of documenting
both the actual declarations of qEnvironmentVariable(), one with a 2nd
parameter for passing a defualt value and one without that parameter.
But the one without the default value parameter was marked internal, so
it didn't appear in the docs.
When both functions were documented with a shared comment, a bug in
QDoc was revealed, because these functions are global, while the shared
comment functionality had only been implemented for class member functions.
Now the shared comment functionality has been implemented for global
functions, so these two functions are now documented with a shared
comment. We can, of course, reintroduce the #ifdef QCLANG_QDOC trick, if
that is pre3ferred.

To read data from a named pipe, QWindowsPipeReader uses the ReadFileEx()
function which runs asynchronously. When reading is completed and the
thread is in an alertable wait state, the notified() callback is called
by the system, reporting a completion status of that operation. Then the
callback queues a readyRead signal and starts a new sequence. The latter
is skipped if the pipe is broken or the read buffer is full.
Thus, if an application does not run the event loop, the next call to
QWindowsPipeReader::waitForReadyRead() should emit the queued signal
and report true to the caller even if no new read operation was started.

The original design for the 64-bit futex had the token count replicated
in the high part. But the constructor wasn't setting it. This is one of
the issues I had noticed when investigating QTBUG-66875, but didn't need
to address since the the fix I ended up applying in commit
081c001deb made that unnecessary: the high
part only had the number of waiters.
Unfortunately, when commit f502270c0f06daba75c1da381bd1658d81aa7bba
brought back the token count in the high part, I failed to correct that
problem. As a consequence, every QSemaphore that was initialized in the
constructor to a non-zero value would eventually deadlock.
This commit fixes that oversight.

This time, the issue was that we could race a wait and a wake. A multi-
token waiter would not notice that the number of tokens changed because
it only performed a fetch-and-OR, then waited on the high part which did
not change. That means the futex_wait() would succeed, when we wanted it
to have failed.
So we have to bring back a portion of what commit
081c001deb removed: we need to keep both
the token count and the waiter count in the high word.

The Q_GADGET macro cannot be used in templates. It can however be useful
to derive a template class from a Q_GADGET enabled base class to benefit
from type safety features in C++ (e.g. the class could represent an id
or handle for some C++ type).
For proper wrapping of a QVariant with a gadget value in a QJSValue, the
QMetaType::IsGadget flag must be set for the registered template
instance type - which does not happen prior to the fix because
IsGadgetHelper requires qt_check_for_QGADGET_macro to be defined in the
registered class but not in an ancestor class - in other words: The
class must declare Q_GADGET.
To overcome this, IsGadgetHelper/IsPointerToGadgetHelper can now
differentiate between a Q_GADGET flagged class (allowing
automatic registration) and a derived class, e.g. a template class
(forcing Q_DECLARE_METATYPE to be used explicitly).
