[$] The rest of the 4.16 merge window

At the close of the 4.16 merge window,11,746non-merge changesets had been merged; that is 5,000 since last week's summary. This merge window isthus a busy one, though not out of line with its predecessors - 4.14 had11,500 changesets during its merge window, while 4.15 had 12,599. Quite abit of that work is of the boring internal variety; over 600 of thosechangesets weredevice-tree updates, for example. But there was still a fair amount ofinteresting work merged in the second half of the 4.16 merge window; readon for the highlights.
