Nyall Dawson abcaba857f Add method to force a detach for QgsSpatialIndex
Since the underlying libspatialindex is not thread safe
on some platforms (e.g. Windows), manual calls to detach()
must be made if a QgsSpatialIndex is to be accessed across
multiple threads.

Note that for platforms on which libspatialindex is thread
safe, calling detach() has no effect and does not force the
deep copy.
