The qfloat16 formatter is based of the std::formatter<float>. It is added in a separate header file qfloat16format.h, so that the users could include it only when they really need. After the C++20 standard was released, it had one important addition that requires the format string to be parsed at compile-time. This feature is covered by __cpp_lib_format == 202106L. The older implementations have slightly different signatures of std::formatter::format() and std::formatter::parse() methods. To avoid ugly macros, Qt only supports std::format if the compilers implement __cpp_lib_format >= 202106L. This commit also defines QT_SUPPORTS_STD_FORMAT macro to avoid constant repetition of if (defined(__cpp_lib_format) && (__cpp_lib_format >= 202106L)) checks. [ChangeLog][QtCore][qfloat16] Added std::format support for qfloat16. The supported formatting options are similar to those of std::formatter for float.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
