9e09677c1d Remove QtDBus includes
Per the discussion of QTBUG-88831, we determined that module-wide
imports are unfortunate, especially for compile times. Following this,
all QtDBus includes have been replaced with the headers for the classes
actually used in each file. Additionally, some cleanup of header file
order and format has been performed in the changed files.

1869615fc9 QChar: make construction from integral explicit
QChar should not be convertible from any integral type except from
char16_t, short and possibly char (since it's a direct superset).

David provided the perfect example:

  if (str == 123) { ~~~ }

compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.

Add a macro to revert to the implicit constructors, for backwards
compatibility.

The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.

[ChangeLog][Potentially Source-Incompatible Changes][QChar] QChar
constructors from integral types are now by default explicit.
It is recommended to use explicit conversions, QLatin1Char,
QChar::fromUcs4 instead of implicit conversions. The old behavior
can be restored by defining the QT_IMPLICIT_QCHAR_CONSTRUCTION
macro.

14090760a8 Long Live QMap as a refcounted std::map!
... and QMultiMap as std::multimap.

Just use the implementation from the STL; we can't really claim that
our code is much better than STL's, or does things any differently
(de facto they're both red-black trees).

Decouple QMultiMap from QMap, by making it NOT inherit from
QMap any longer. This completes the deprecation started in 5.15:
QMap now does not store duplicated keys any more.

Something to establish is where to put the
QExplictlySharedDataPointer replcement that is in there as an
ad-hoc solution. There's a number of patches in-flight by Marc
that try to introduce the same (or very similar) functionality.

Miscellanea changes to the Q(Multi)Map code itself:

* consistently use size_type instead of int;
* pass iterators by value;
* drop QT_STRICT_ITERATORS;
* iterators implictly convert to const_iterators, and APIs
  take const_iterators;
* iterators are just bidirectional and not random access;
* added noexcept where it makes sense;
* "inline" dropped (churn);
* qMapLessThanKey dropped (undocumented, 0 hits in Qt, 1 hit in KDE);
* operator== on Q(Multi)Map requires operator== on the key type
  (we're checking for equality, not equivalence!).

Very few breakages occur in qtbase.

[ChangeLog][Potentially Source-Incompatible Changes] QMap does not
support multiple equivalent keys any more. Any related functionality
has been removed from QMap, following the deprecation that happened
in Qt 5.15. Use QMultiMap for this use case.

[ChangeLog][Potentially Source-Incompatible Changes] QMap and
QMultiMap iterators random-access API have been removed. Note that
the iterators have always been just bidirectional; moving
an iterator by N positions can still be achieved using std::next
or std::advance, at the same cost as before (O(N)).

[ChangeLog][Potentially Source-Incompatible Changes] QMultiMap does
not inherit from QMap any more. Amongst other things, this means
that iterators on a QMultiMap now belong to the QMultiMap class
(and not to the QMap class); new Java iterators have been added.

6d880185b1 Fix passing QDBusUnixFileDescriptors over peer-to-peer connections
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.

And name the main class QList. That's also the one we document.

This gives less porting pain for our users, and a lot less churn
in our API, as we use QList in Qt 5 in 95% of our API.
In addition, it gives more consistent naming with QStringList and
QByteArrayList and disambiguates QList vs QVector(2|3|4)D.

33cd680ddb New QMetaType representation
the QMetaType is represented as a pointer to a "vtable" in the form of
a QtPrivate::QMetaTypeInterface*

The recomanded use of QMetaType is to construct an object with
QMetaType::fromType. This does not require any registration.

There is still an id() function which will do some registration
for compatibility with Qt5. Also the patch does not really touch
the other extra things that can be registered (data stream operator,
comparison operator, iteratable, ...) and this still uses the previous
system.

This is only the change in QMetaType, other changes to use it in QVariant
and QMetaObject will follow

34fe9232db Port from QAtomic::load() to loadRelaxed()
Semi-automated, just needed ~20 manual fixes:

$ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)load\(\)/$1loadRelaxed\(\)/g' -i \{\} +
$ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} +

It can be easily improved (e.g. for store check that there are no commas
after the opening parens). The most common offender is QLibrary::load,
and some code using std::atomic directly.

0efe6fc90f Don't link against dbus-1_nolink when dbus_linked feature is off
dbus1_linked is only evaluated to true when the dbus package is found.
If it was not found, then it makes no sense to link against the
_nolink target, because no package was found in the first place.

When the package is not found, QtDBus uses a minimal dbus header which
is included with QtDBus sources, so there is no need for the _nolink
target.

This amends cc141cc5c6 and fixes a build
failure on macOS.
