The responsibility of sendWindowSystemEvents() is to process events from
the window system. Historially that logic was part of the QPA/QWS event
dispatcher, which naturally also sent posted events. Through refactoring,
the code at some point ended up in in the QWindowSystemInterface class,
still with the posting of events in place.
This resulted in QPA event dispatchers adopting a pattern of just calling
sendWindowSystemEvents(), as that would cover both posted and window system
events. Other event dispatchers would call sendWindowSystemEvents(), and
then use a base-class implementation from QtCore for processing events,
resulting in two calls to QCoreApplication::sendPostedEvents() per
iteration of processEvents(). This breaks the contract that processEvents
will only process posted events that has been queued up until then.
We fix this entanglement by removing the sendPostedEvents() call from
QWindowSystemInterface::sendWindowSystemEvents() and move it to the
respective event dispatchers. For some EDs it means an explicit call
to sendPostedEvents, while others were already doing sendPostedEvents
though a separate source (GLib), or using a base-class (UNIX/BB), and
did not need an extra call.
We still keep the ordering of the original sendWindowSystemEvents()
function of first sending posted events, and then processing any
window system events.

Our previous event loop integration had two unfortunate flaws:
1. We would call qt_user_main() from a timer, after returning from
didFinishLaunchingWithOptions. This had the effect of showing the
iOS application window long before the Qt application UI had been
set up, resulting in a 1-2 second flash of black/pink between the
launch image disappearing and the actual application showing.
2. We spun a nested event loop, where our implementation of the
different event loop modes did not perfectly match the Apple
implementation. This resulted in scrolling being busted in
some cases such as when showing the virtual keyboard for
Emoji characters.
These two issues have now been solved by calling the user's main()
from didFinishLaunchingWithOptions. Normally this would not work, as
the user's main would call QApplication::exec() at the end of their
main(), which would block and we would never return back from the
didFinishLaunchingWithOptions callback, resulting in no UI on screen.
We work around this by longjmp'ing out of QApplication::exec(), back
into didFinishLaunchingWithOptions, so that it can return. Again,
this would normally not work, as the call stack where QApplication
and friends would live would get smashed as the application
continued executing. We work around this by allocating a block
of stack space at the start of main(), which we then redirect the
stack pointer to before calling the user's main. This results in
the whole stack of the user's main() and below being preserved, even
if we longjmp out of the call stack (which then restores the
stack pointer).
This approach should work fine together with garbage-collection as
well, since the mark-and-sweep phase will walk the stack from the
stack pointer to the stack base, including sections of the stack
that were part of qt_user_main() and live in the reserved area.
One case where GC will fail though is if it happens as part of the
qt_user_main() call, where the GC will not mark anything in the
'real' callstack below UIApplicationMain(), but this is not
expected to happen.
The size of the reserved stack can be controlled through the
Info.plist key 'QtRunLoopIntegrationStackSize', as well as the
'QtRunLoopIntegrationDisableSeparateStack' key to disable the
separate stack approach completely. This will fall back to the
old approach. The amount of stack space used by the user's
main can be determined by enabling a special debugging mode,
using the 'QtRunLoopIntegrationDebugStackUsage' key.

Instead of using a define to rename the user's main() function during
compilation, we leave the user code alone, and inject our wrapper one
step earlier in the process, at the application entry point 'start'.
This entry point is provided by crt1.o, which is normally linked into
the application automatically. The start() function sets up some state
and then calls main(), but we change the start() function to instead
call our main wrapper.
Instead of shipping our own crt1 binary/sources, we make a copy of
the appropriate crt1.o at build time, and modify its symbol table in
place. This is unproblematic as long as we keep the same length for
the wrapper function name, as the symbol names are just entries in
the global string table of the object file.
The result is that for the regular Qt use-case the user won't see
any changes to their main function, and we have more control over
the startup sequence. For the hybrid use-case, we no longer rely
on the fragile solution of having our back-up 'main' symbol in
a single translation unit, which would break eg with --load_all,
and we don't need to provide a dummy 'qt_user_main' symbol.
OSX 10.8 and iOS 6.0 introduced a new load command called LC_MAIN,
which places the state setup in the shared dyld, and then just
calls main() directly. Once we bump the minimum deployment target
to iOS 6.0 we can start using this loader instead of LC_UNIXTHREAD,
but for now we force the classic loader using the -no_new_main flag.
There's also a bug in the ld64 linker provided by the current Xcode
toolchains that results in the -e linker flag (to set the entry
point) having no effect, but hopefully this bug has been fixed
(or Apple has switched to the LLVM lld linker) by the time we
bump our deployment target.

When the QIOSApplicationState object owned by the platform integration
was deleted we would deallocate QIOSApplicationStateListener, but would
then get a callback on the main queue later on where we would reference
the now invalid 'this' variable.
By moving the dispatch_async call to QIOSApplicationStateListener and
using 'self' we ensure that the listener is retained for as long as the
block is valid. This opens us up for receiving application state callbacks
after QCoreApplication has been deleted, so we need to guard against
that.
