Revert "Revert 83168 - Revert "Revert 83100 - Remove weird dependency on extensions from webui.Re-plumb extension request messages in a more sane way.Before, each RVH had ProcessWebUIMessage(), which wasserving as a manual way of plumbing both WebUI andextension messages to the right place, even though onlya few RVHD responded to either message.Instead of this, we now just teach more of the stack howto handle IPC messages in general, and delegate them upthrough the stack, giving each layer a chance to handlethem if it knows how.The result is simpler and smaller:179 insertions(+), 252 deletions(-)BUG=80311Review URL: http://codereview.chromium.org/6901021"This reverts commit 643b280cedd9f0b76948686f39f50f295aba362f.TBR=mpcomplete@chromium.org"
