Fixes the bug in QFile which allowed opening a file with reserved
characters in its name. If the name is a long file path, CreateFile
opens a file with a truncated name instead of failing, so we have
to catch reserved characters ourselves.
[ChangeLog][Windows] Fixed a bug that caused QFile to create
files with truncated names if the file name was invalid. Now,
QFile::open correctly fails to create such files.
