Nathan Froyd 8780083336 Bug 1161627 - part 2 - machine-convert TemporaryRef<T> to already_AddRefed<T>; r=ehsan 
This conversion was done with the script:

  find . -name '*.cpp' -o -name '*.h' -o -name '*.mm' -o -name '*.idl' | \
    egrep -v 'cairo-win32-refptr.h|RefPtr.h|TestRefPtr.cpp' | \
    xargs sed -i -e 's/mozilla::TemporaryRef</already_AddRefed</g' \
                 -e 's/TemporaryRef</already_AddRefed</g'

Manual fixups were performed in the following instances:

- We handled mfbt/RefPtr.h manually so as to not convert TemporaryRef itself
  into already_AddRefed.

- The following files had explicit Move() calls added to make up for the lack
  of a copy constructor on already_AddRefed:

  dom/base/ImageEncoder.cpp
  dom/media/MediaTaskQueue.{h,cpp}
  dom/media/webaudio/PannerNode.cpp

- A redundant overload for MediaTaskQueue::Dispatch was deleted.

- A few manual fixups were required in mfbt/tests/TestRefPtr.cpp.

- Comments, using declarations, and forward declarations relating to
  TemporaryRef in dom/canvas/ and gfx/layers/ were changed to refer to
  already_AddRefed.
