Android: Don't call requestLayout() when changing the geometry.

requestLayout() is already called when setLayoutParams() is called, so
calling it again is extremely wasteful.

When creating SSL context failed due to unsupported protocol being

Fix memory leak in QClipboard::setMimeData()

The setMimeData() function is documented to take ownership of
the object passed in, but in the case where the platform
plugin did not support the requested mode, we would simply
return without deleting the object nor telling the application,
so it would cause a potential memory leak. We need to honor the
contract, even when we fail to set the mime data.

Test was updated to avoid verifying the leak in cases where
the platform does not support all modes.

Android: Make memory handling in QClipboard consistent with iOS

On iOS we do deleteLater() on the mime data instead of deleting
it directly, in case the application should happen to use the
pointer again directly after setting it on the clipboard.
Technically it would be a bug in the application, but using
deleteLater() is safer and it's better to be consistent with
iOS so that a buggy application crashes in the same places in
both.

OS X: rename special menu items instead of duplicating

Two-part fix: QCocoaMenu::syncMenuItem, when selecting the "old" menu,
if an item was merged, 'applicationMenu' was always selected, but this
is wrong for any item with a role >= CutRole (such an item still can
be "merged", but it's not in the application menu).

QCocoaMenuItem::sync - item can be merged with itself: after item's
role detected, the search for an item to merge with can find exactly
the same item we've just detected the role for (since a data-member is
modified) - try to avoid this.
