base::lambda -> Fn (type alias for std::function).
base::lambda_once -> FnMut (type alias for base::unique_function).
base::lambda_guarded -> crl::guard.
base::lambda_call_type_t -> crl::deduced_call_type.
Move logs:SignalHandlers to core/crash_reports:CrashReports.
Move all pre-launch windows to core/crash_report_window module.
Move some global code to core/launcher:Launcher.
It should replace settings / platform_specific module in some way.
Regression was introduced in df64c97.
New base::flags work correctly only if all mutually exclusive flag
values use mutually exclusive bits (a & b == 0 for exclusive (a, b)).
Closes#3856.
We had several reports about wrong values in registry on Windows 8.1,
like the quiet hours are enabled and all notifications are skipped,
without anything like that being enabled in Windows settings.
Use Qt::Dialog instead of Qt::Tool which works better with window
activation / deactivation handling.
Stop displaying the panel on all spaces when the call is established.
Also implement panels that appear in all spaces on macOS.
Using them for calls panels and custom notifications, so it
will be possible to use custom notifications in macOS as well.
Also add some more decoders in ffmpeg configuration (wav).
Also stop audio device restart on PKEY_AudioEndpoint changes.
Also deduce channel layout from channel count in ffmpeg loaders.
Currently the build without implicitly included precompiled header
is not supported anyway (because Qt MOC source files do not include
stdafx.h, they include plain headers).
So when we decide to support building without implicitly included
precompiled headers we'll have to fix all the headers anyway.
Some major platform-dependent file operations refactoring.
All methods like "open file", "open file with", "show in folder"
were moved to core/file_utilities module with platform-dependent
backends. All methods interacting with DesktopServices made async.
Now each platform-dependent module declares its interface in
platform/platform_module.h file and after that includes platform-
specific headers like platform/win/module_win.h with implementation.
Also removed the legacy WinRT platform-dependent implementations.
