Namely, they shouldn't be supported. Even trying to create such a type
(as in QMetaType::fromType<int &>()) should fail, because for the
purposes of the meta type, they are not the same.
However, they were being registered in the meta objects' meta type list
as a mistake since commit cb43aaca11
("Introduce QMetaObject::metaType"), including for output parameters in
D-Bus remote objects' meta objects. despite the comment saying "type id
not available".
[ChangeLog][Potentially Source-incompatible Changes] Made meta types for
non-const references fail to compile. Previously, QMetaType::fromType
allowed this to compile, but returned the meta type for the base type,
which was incorrect. Const references are understood to be the same as
the base type.
[ChangeLog][Important Behavior Changes] The meta type for non-const
reference parameters in extracted methods (signals, slots, etc.) is no
longer available in QMetaMethod. This used to be the case in Qt 4.x and
5.x, but due to a mistake in Qt 6.0-6.3, QMetaMethod would incorrectly
report the base (non-reference) type. Additionally, both the reference
and the non-reference types may have been reported in different APIs.

This is part of a series of patches deprecating implicit conversions
of QAtomic<T> variables to T.
Use relaxed atomic loads and stores on the 'isDebugging' variable. The
old code used the implict conversions to and from int and therefore
loadAcquire/storeRelease. Here, the int is the only value, it's not
guarding the construction of any other data, so relaxed loads and
stores suffice.
A further optimization would be to make the initial value of
isDebugging 0, to send it into the BSS instead of the TEXT/DATA
segment, but seeing as this is just compiled in for the auto-tests,
this patch leaves that particular change for another round (or never).

CMake silently drops empty list items when passing ${someVar} to a
function unquoted. The versionless wrapper functions typically use
${ARGV} or ${ARGN} to pass through arguments from the caller to the
versioned implementation, but this doesn't preserve empty arguments.
For qt_add_dbus_adaptor() in particular, this was problematic because
that meant arguments after the empty arg effectively "moved left" and
were interpreted as the wrong arguments.
Use named arguments and pass through each one explicitly for the
qt_add_dbus_adaptor(). This takes advantage of the implementation of
the versioned function, which also checks each optional positional
argument explicitly. We can only do this because we know the upper
bound on the number of arguments, so it is possible to represent each
argument with its own variable. A more general solution that didn't
need to know the number of arguments would require the
cmake_language(EVAL) command, but that requires CMake 3.18 or later.

This function returns the metatype corresponding to the metaobject, or
an invalid metatype for namespaces.
This works as follows: First we increment the metaobject revision for
new metaobjects. Metaobjects with older revisions are handled by doing a
lookup by name. That fallback is also used for dynamic metaobjects (from
QtDBUS and those created by QMetaObjectBuilder).
For new metaobjects, we store the metatype in its metatype array, behind
the property metatypes. This avoids any changes to the property and
method metatype extraction logic: For properties, the metatype access
does not change, as the new metatype is after their metatypes. For
method metatypes, we already have an indirection layer (using offsets),
so by adjusting those offsets by one, the same logic keeps working.
To distinguish between namespaces and dynamic metaobjects, namespaces
store the metatypeinterface pointer for void in the metatype array,
whereas dynamic metaobjects store a nullptr.
One nice additional benefit is that this simplifies the generator logic
in moc, as the metatype array is now never empty.

And remove the old manual registration code for those operators.
Add some special handling for long/ulong, as these types could be
streamed as a QVariant so far, but are not directly streamable
through QDataStream.
[ChangeLog][QtCore][QMetaType] The QMetaType::registerStreamOperators()
and QMetaType::registerDebugStreamOperator() methods have been
removed. The streaming operators for a type are now automatically
registered together with the type registration. This implies that the
operators should be visible wherever the type is visible and being used.
[ChangeLog][Behavior Incompatible Changes] Because the QDataStream and
QDebug serialization operators are automatically registered with
QMetaType, the declarations of those functions must be present at any
point where the type is used with QMetaType and QVariant.

While trying to implement instructions for building examples with
qmake in the CI, an issue has surfaced.
When building examples with CMake with -DBUILD_EXAMPLES=ON in the CI,
the examples are built in-source, aka source dir == build dir.
This means that the header files generated by qdbusxml2cpp will be
placed in the qtbase source dir.
The instructions that try to build examples with qmake build the
examples in a separate build dir after building the examples with CMake.
Unfortunately the qtbase/examples/dbus/remotecontrolledcar/car example
includes the generated DBus adaptor header via a statement like
#include "car_adaptor.h"
and the compiler prefers to pick up the header file from the example
source dir (the one generated by CMake), rather than the one generated
by qmake in the example build dir.
Because CMake's DBus integration uses different flags than qmake's
DBus integration, the generated header file code is not compatible
with the qmake generated cpp file, and the example fails to link when
building with qmake, because it can't find an appropriate constructor
symbol.
In an ideal world, we wouldn't do in-source builds with the CMake
build, but that leads to other issues which I currently don't recall.
To circumvent the issue, adapt the CMake DBus qt6_add_dbus_adaptor
function to allow not passing the problematic '-l' flag by making it
optional. This shouldn't break existing code, but allows us to
generate a compatible header that will be used by qmake and succeed in
linking the example.

Passing QDBusUnixFileDescriptors over peer-to-peer connections currently
does not work, because QDBusConnectionPrivate::setPeer() does not set
this->capabilities (unlike QDBusConnectionPrivate::setConnection()
which is executed for bus connections).
Keep track of whether the connection already has been authenticated, and
once the connection does get authenticated, update this->capabilities.
Note that sending a message directly after connecting (before any
message has been received from the peer) might still fail if the message
contains a QDBusUnixFileDescriptor.
