The twentieth century is now some way behind us, so using its years
when parsing a date-time format that only provides the last two digits
is increasingly likely to produce unwelcome results. Most such formats
are saved by the "redundant" presence of a day-of-week field but, for
those that are not (notably including ASN.1 date fields), there is a
need to provide some way to over-ride the twentieth century default.
Allow the caller to pass a base year to the fromString() methods, of
QDate and QDateTime, and to QLocale's toDate() and toDateTime(), that
indicates the first of 100 consecutive years, among which the two
digits given can select a year. Add some test-cases to exercise the
new API.
[ChangeLog][QtCore][QDate] When fromString() has only a two-digit year
to go on, it is now possible to set the start-year of the century

qCompareThreeWay() is a top-level wrapper around the helper
three-way comparison methods, which is mostly convenient for

When implementing compareThreeWay() for Qt types, we normally
provide the implementation only for (LeftType, RightType) pair,
but not the reversed one.
However, it is expected that qCompareThreeWay() would be available
for both combinations, because the reversed result can be easily
calculated.

We accepted QSpan as a NIH-type instead of waiting for C++20 and
std::span, because we said that there's no impedance mismatch between
the two, as they both implicitly convert into each other.
But we actually never checked that they do.
Fix this omission by adding constructors that treat std::span exactly
the same as QSpan itself, and adding the respective static_assert()s
to tst_QSpan to check that (within the constraints imposed by the
standard on std::span), they actually do convert into each other.
The only two problematic cases are that fixed-size std::span
constructors are explicit, so span is only constructible, not
convertible, from QSpan. Likewise, for an rvalue QSpan to be
acceptable to the std::span constructor, QSpan needs to opt-in to
enable_borrowed_range (while we're at it, do enable_view, too).
We so far have rejected adding these opt-ins for our own container
classes because we wanted to avoid the compile-time overhead of
including the huge <ranges> header into such central headers as those
that define our containers.
But std::span itself has to specialize these traits, and its range
contructor has to use them, so they must be available from <span>,
too, possibly the stdlib puts the definition into a much smaller
header. So just assume we can specialize it after including just
<span>, provided __cpp_lib_concepts is also defined.

for C++20 only the overloads for opeartor==() and operator<=>() are

The macros are documented as internal for now.
The macros rely on two helper functions:
bool comparesEqual(LeftType lhs, RightType rhs);
ReturnType compareThreeWay(LeftType lhs, RightType rhs);
The comparesEqual() helper function is used to implement operator==()
and operator!=().
The compareThreeWay() helper function is used to implement the four
relational operators in C++17, or operator<=>() in C++20.
ReturnType must be one of Qt::{partial,weak,strong}_ordering.
When possible, the functions should also be declared constexpr and

It's the user's responsibility to provide the functions before

classes, and uses the new helper function to verify the comparison
results.

A severe incompatibility was detected in 2.3, which is why 2.4
is being released so soon afterwards. The mimetype for *.bz2 files
changed (from bzip to bzip2), breaking much code in KDE for instance.
This is now handled in a more compatible way. And the two last-minute
fixes in the Qt copy of 2.3 are part of 2.4, so this is now more in line
with upstream shared-mime-info.

It's the actual system call on Linux, inspired by the 4.4BSD call of the
same name (and our BSD code also uses statfs(), except for NetBSD, but
it probably could use statfs() there too). statvfs() wasn't introduced
until POSIX.1-2001, though glibc added it in 1998 for version 2.1 and
Bionic only for NDK version 19 in 2019.
So we could merge the Android code to the POSIX version, but it's easier
to merge the non-Android code to the raw system call.

This fixes an infinite loop reported by a user who had both the
definition of text/javascript from shared-mime-info 2.3 and the
definition of text/javascript from shared-mime-info 2.4 installed at the
same time. In 2.3, text/javascript is a subtype of
application/ecmascript, but in 2.4 application/ecmascript is a subtype
of text/javascript. Having both at the same time resulted in circular
inheritance.

[ChangeLog][QtCore][QMimeDatabase] Added code to detect and break
circular inheritance loops in the MIME data, which were causing infinite
loops

the QtDisplayManager listener uses m_layout but it can be called
before m_layout is actually initialized, so set the listener after
the layout has been initialized.

When interfacing with C-style APIs, such as the Windows API, resources
are often represented using handle objects. Lifetime management of such
resources can be cumbersome and error prone, because typical handle
objects (ints) do not give any help to release resources, and to manage
ownership.
Although std::unique_ptr can be retro-fitted with a custom deleter, and
helps transfer of ownership, it is inherently a pointer type. It can
therefore be clumsy to use with C-style APIs, particularly if the
invalid (uninitialized) handle value is not a nullptr. Also, the
std::unique_ptr does not work well when an allocating function returns
the handle as a pointer argument.
The QUniqueHandle addresses these issues by providing a movable only
value type that is designed as a RAII handle wrapper.
A similar handle wrapper exists in the Windows SDK, as part of the WRL
library. Unfortunately, this is Microsoft specific, and is not supported
by MINGW.
Since the QUniqueHandle is platform independent, it can be used also
with non- Microsoft platforms, and can be useful with other C-style APIs
such as FFmpeg or SQLite.
