- Remove the casting operator of QFuture<T> to T. It calls
QFuture::result(), which may lead to undefined behavior if the user
has moved the results from QFuture via QFuture::takeResult() before
trying to do the conversion.
- Disable implicit conversion of QFuture<T> to QFuture<void>, by making
the constructor explicit. If the users really intend to do the
conversion, they should do it explicitly.

of QFuture<T> to T and to QFuture<void> have been disabled. Use

For the comparison of a QFuture<int> and an int, gcc creates code that

QFuture<int> future;
int five = 5;
if (future == five)
return five;

QtConcurrent algorithms are making an internal copy of the passed
sequence, to make sure it won't be destroyed before the execution
is finished. However, they were using iterators of the originally
passed sequence. So, if the original sequence is deleted, QtConcurrent
algorithms would use invalid iterators to a deleted sequence. This
might work with Qt containers thanks to implicit-sharing, but with
other containers will lead to unexpected results. Fixed them to work
on the internal copy of the original sequence.

Replace the implementation of blockingMappedReduced():
after calling non-blocking version of mappedReduced() we are getting
the future object, so we may call in sequence result(), which
will block and return the result when the all tasks are done.
The same is done with blockigMapped(), which calls blockingMappedReduced()
with a custom reduce function.
Looks like with this pattern we can reuse the non-blocking version
for implementing blocking version of mapped / filtered methods.
