It's not completely implemented so we should crash early rather than have
people use it by mistake.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This commit was generated using the following script, executed at the
top level of a typical source code checkout.
# Don't modify select files in mfbt/ because it's not worth trying to
# tease out the dependencies currently.

# Don't modify anything in media/gmp-clearkey/0.1/ because those files

The bulk of this commit was generated by running:

-header-filter=^/.../mozilla-central/.* \
-fix
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.
This let's us avoid depending on Save() and Restore() to have the
right transform at the right time.

Having this implicit conversion means that we can silently do extra
refcounting when it's completely unnecessary. It's also an obstacle to
making RefPtr more nsRefPtr-like, so let's get rid of it.
When a method returns type D derived from RefCounted type B, there is an
ImplicitCastExpr (or an ExplicitCastExpr, if there is an explicit cast
to the base type in the code) in the AST between the CallExpr and
MemberExpr, which we didn't take into account before. This caused the
analysis to not work on common patterns such as
nsCOMPtr<nsIXPCOMInterface>.
When viewing about:memory in verbose mode this reduces the number of heap
allocations by over 10%.
