cef/libcef/browser/browser_host_impl.cc
Marshall Greenblatt b3a8da9b25 Add CefAppManager and remove global ContentClient accessors (see issue #2969) 
This is the first pass in removing direct dependencies on the Alloy
runtime from code that can potentially be shared between runtimes.

CefBrowserHost and CefRequestContext APIs (including CefCookieManager,
CefURLRequest, etc.) are not yet implemented for the Chrome runtime.
Assert early if these API methods are called while the Chrome runtime
is enabled.
