Remove unnecessary QDateTime::detach() function

Last commit changed QDateTime::d to be a QSharedDataPointer that
implicitly detaches on non-const operator->() calls. That means we no
longer need to explicitly call detach().

More than that, we should not do it, so we avoid checking the ref count
and try to detach on every use. To do that, in functions where the d
pointer was accessed more than once, I detach at the top and shadow the
"d" variable with a local plain pointer. We don't compile our sources
with -Wshadow, so this should not be a problem.
