Cocoa: Improve expose event handling.

Send expose events on window and view show/hide
notifications. Implement QCocoaWindow::isExposed.

Close all windows on quit. This allows sending (de-)expose
events for those windows while the event loop is running.

Remove the flushWindowSystemEvents call in setVisible.
This function is called from application code. Flushing
window system events here is wrong since it can lead
to events being processed in the middle of the user
code call stack. flushWindowSystemEvents should only
be called as a result of (native) window system activity.

Skip one of the tst_qtooltip tests which becomes unstable/
fails in the CI system as a result of this change.

Fixed potential access violation in QPixmap::copy() for <32 bit pixmaps.

QImage is supposed to maintain the invariant that each scan-line begins
on a 4-byte boundary, so we need to verify that this is the case before
using the optimized path of short-cutting QImage::copy() by referencing
the source image's bits directly.

require modules to define their version

otherwise they would inherit it from qtbase, which may effectively
result in a lie if building against a different release.

for convenience we define the version centrally per repo.
qtbase is special, in that we use the version defined in qglobal.h to
avoid defining it redundantly (the instance in qglobal.h is currently
needed to bootstrap qmake; the configures would need some work to change
this).
