mac80211: rt2x00: import upstream changes and rebase our patches

Some of our local patches have been accepted upstream. And there are
some more relevant changes (mostly for rt2800usb). Import them and
rebase our remaining local patches on top.

+Subject: [PATCH 11/19] rt2x00: separte clearing entry from rt2x00lib_txdone
+
+This makes rt2x00lib_txdone a bit simpler and will allow to reuse
+code in different variant of txdone which I'm preparing.
