------- Additional Comments from Nate Chapin <japhet at chromium.org>
This patch required some extra shifting around (namely, I moved a bunch of
CachedResourceHandleBase into CachedResourceHandle.cpp because of #include
cycles).

I mostly tried to piggyback off of RefPtr and PassRefPtr, but I don't know this
stuff well enough to be confident that I got it right and avoided refcount
churn.
