Hmm.... so the reason we have these is for const-correctness. There seems to
have been multiple diverging opinions on this in the past. I'm personally OK
with removing them, but I think it's probably worth a short style discussion
with people like jbroman, haraken, danakj, pkasting, etc so we don't keep going
back and forth on this.

Abandoning patch; as per discussion on cxx@chromium.org, this work should
require careful refactoring to achieve "const okay"-ness.

NB: Changing the methods to "const Foo& GetFoo() const" results in many compile
errors.
