0749ba2c5e Rewrite the Info.plist variable replacement handling
This ensures that the same set of variables can be successfully replaced
in both the Makefile and Xcode generators. It also switches the default
templates to use the Xcode-style ${var} syntax instead of the @var@
syntax for better Info.plist compatibility across generators.

eef2d1af33 unify windows mkspecs: reorder variables and flags
Common changes to mingw-w64, ICC on Windows, and MSVC toolchains:
- set similar order of variables and its splitting into sections,
- set similar order of flags in variables and the way they are set.

mingw-w64 toolchain:
- move 'gcc-base.conf' include before setting Windows specific
  flags, similar to include 'msvc-desktop.conf' in ICC on Windows
  toolchain; this leads to consistency with other toolchains
  and allows to safely override common GCC variables with Windows
  specific ones, when needed,
- move 'QMAKE_EXT_OBJ' and 'QMAKE_EXT_RES' variables to the linker
  flags section, according to its purpose.

MSVC toolchain:
- set flags order in 'CONFIG' variable, similar to mingw-w64 toolchain.

mingw-w64 toolchain:
- remove 'QMAKE_CXXFLAGS_THREAD' variable definition, since
  'QMAKE_CFLAGS_THREAD' variable not set for mingw-w64 toolchain.

ICC on Windows toolchain:
- remove 'QMAKE_LFLAGS', 'QMAKE_LFLAGS_RELEASE',
  'QMAKE_LFLAGS_RELEASE_WITH_DEBUGINFO' and 'QMAKE_LFLAGS_DEBUG'
  definitions, since they're properly set in 'msvc-desktop.conf',
- remove 'DSP_EXTENSION' variable, which doesn't occur anywhere else
  within QtBase; its most recent search results relate to
  Visual Studio 6.0 and Intel Fortran.

dc0bb57f86 Fix an issue causing asset catalogs to be miscompiled with iOS simulator
This works around the inability to build iOS apps for a "generic"
simulator by explicitly setting the Xcode build setting
ENABLE_ONLY_ACTIVE_RESOURCES to NO in order to ensure that all variants
of assets in an asset catalog are built when targeting iOS simulator
devices. Otherwise, we will simply build for whatever the first
simulator in the list happens to be. If the application is then deployed
to a different simulator, some of the assets needed for that device
variant may be missing.

This "helps" QTCREATORBUG-19447 but is not a workaround since this fix
is necessary for command line builds anyways, even though it's unlikely
to crop up in practice there, since one would have to manually deploy
the built application bundle to the simulator using simctl rather than
going through Xcode (which would rebuild for the appropriate device).

8dfcc3b023 configure: reset *_LIBS when *_LIBS_{DEBUG|RELEASE} are specified
it could be somewhat surprising that specifying variant-specific libs
would not clear the common libs, so do that. of course, the default

variant-specific libs, in which case clearing them would be surprising
in turn - luckily, we have no such case.

0dc025bf9f Fix macOS shadow prefix builds using pre-synced source packages

executed before configure, with outdir set to srcdir, and this
caused path misalignments for injected headers in qt_module.prf

paths relative to the source dir.

31cc29e9be Disable Xcode main thread checker by default
Xcode 9 introduced the main thread checker, which detects invalid
use of AppKit, UIKit, and other APIs from background threads.

https://developer.apple.com/documentation/code_diagnostics/main_thread_checker

In our case these are accesses to e.g. [UIView layer] and
[UIScreen scaleFactor] from the render thread of QtQuick,
things we should look at, but that might not be easily solvable.

In any case, these are not warnings the user can do anything about,
so in lack of a per-library disable of the checker, we have to
globally disable it for the whole Xcode project.

This warning used to be part of -Wconversion, but that generates too

importantly, it triggers on passing floats to ints.

fabedd399e Introduce OBJECTIVE_HEADERS
When a ObjC++ QObject subclass is listed in the regular HEADERS, qmake
creates a .cpp file. The moc file will then fail to compile, as it
requries ObjC++ headers. Using Q_FORWARD_DECLARE_OBJC_CLASS() can be
used to let the class be parsed by The compiler, but link will still
fail, as the generated methods (e.g. signals) must be built with ObjC++
compiler, in case they have ObjC parameters:

 Q_FORWARD_DECLARE_OBJC_CLASS(NSString);

 class MyClass: public QObject {
     Q_OBJECT
 signals:
     void objcSignal(NSString * myObj);
 };

The canonical workaround for that is including the .cpp file into the
corresponding .mm file. This also offers a compilation speed advantage,
but is somewhat counter-intuitive.

Therefore, we introduce a separate variable which instructs moc to create
.mm files directly.
