nit: here and in the rest of the change, the convention is to include _impl.h
headers for interfaces inside content. this is to match the WebKit API. the
reason is that later on if we need to cast to the impl, we don't need to change
the includes. that and the public headers are for embedders

[John Grabowski, 2012/06/12 01:46:29]

Sure.  Is there a convention for what files have _impls?  I can see
web_contents_impl.h, but can't otherwise eyeball a list of #includes to know
which ones to convert over.

if there's an interface in content/public that is implemented in content,
there'll usually be an impl
