QtTest: Don't crash when -callgrind is used on QTEST_APPLESS_MAIN

If there's no qApp, then QCoreApplication::arguments() returns an empty
list (after printing a warning). That means the callgrind runner can't
get the arguments it needs in order to rerun the benchmark.

The crash happens because it always uses .at(0) to try and get the
executable's path. Even if we get the path from somewhere else, we still
need the arguments.

in a function definition without changing its declaration, while
it was actually intending to add this as a new overload.

Windows differs from the other platforms in that transient

Cocoa: QImage -> CGImage conversion cleanup

Move to one qt_mac_toCGImage function that has simple
semantics and properly retains a copy of the QImage
for the lifetime of the CGImage.

Remove the old qt_mac_toCGImage function which had
two problems:

1) It would not retain the QImage data (this was probably
ok for its original use case: creating short-lived
CGImages for the paint engine)

2) It had acquired a somewhat odd **datacopy out
parameter for the cases where you _do_ want to retain
the image data.

This makes the exported image conversion function
from QtMacExtras work: The CGImages it creates will
no longer reference free'd memory once the QImage
is deleted.
