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.
