Subject: QFileSystemModel: fix permission mangling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The old code masked out write flags before returning permissions
from permissions() or data(FilePermissions) in order to force
QFileDialog to disable the rename and delete actions. This was to
fix Task 143519, but introduced QTBUG-20503.

Instead, revert to the pre-143519-bugfix code and do the necessary
check in QFileDialog directly.

Also add a testcase for 143519.

Reported-by: Gilles Pascual
Task-number: QTBUG-20503
Task-number: 143519
