Renderer-side changes for browser plugin

Major Classes:

BrowserPluginChannelManager: Manages GuestToEmbedderChannels. It essentially wraps a map that is keyed on channel names.

GuestToEmbedderChannel: Is a Dispatcher. Receives/Sends Ppapi messages. Keeps track of all RenderViews that have an associated PP_Instance in a map (RenderViews that are guests). brettw@ might want to have a look here?

BrowserPluginRegistry: Wrapper around map that keeps track of Browser Plugin PluginModules keyed on the guest process id. This is similar to the PepperPluginRegistry but has a different key type.

BrowserPluginVarSerializationRules: Temporary do nothing class as suggested by brettw@

BrowserPlugin: Towards becoming a wrapper around a WebPluginContainerImpl that swaps out WebPluginImpl/WebViewPlugin on navigation. We get a blank WebViewPlugin (is this a best thing to do to get a blank placeholder?) if we have an empty src attribute or while we're navigating for the first time. Otherwise, on cross-process navigations, we substitute one WebPluginImpl for another WebPluginImpl. TODO: BrowserPlugin should track the lifetime of WebPluginContainerImpl, but right now it lives forever which is bad. Will fix this in a subsequent patch. This requires some WebKit changes first.
