d3dvideosink: First destroy the window, then unregister the class

It's impossible to create another pipeline with d3dvideosink after disposing
the previous one due to some problem in d3dvideosink. The message is: "Unable
to register Direct3D hidden window class".

I've evaluated the problem and it's that UnregisterClass() in working thread is
called before DestroyWindow() and UnregisterClass() does nothing.

uridownloader: fix deadlock near EOS

A deadlock can happen when the source sends EOS when
being put to NULL as the object lock is being held by the
thread that sets the element to NULL and is needed by
the event handler.
uridownloader: Always release the object lock in gst_uri_downloader_fetch_uri_with_range()

even if downloader->priv->urisrc is not set. This avoids deadlock under some
some conditions on cancel.
