Bug 1238160 - Set docshell isolation mode. r=smaug Renames nsDocShell isBrowser* attributes to add a "Moz" prefix for clarity. Adds nsDocShell::GetIsIsolatedMozBrowserElement, which parallels GetIsInIsolatedMozBrowserElement, but only checks the immediate docshell. Adds nsDocShell::SetIsInIsolatedMozBrowserElement for the frame loader and tab child to set the isolation state. nsDocShell methods related to mozbrowser elements (and their callers) are updated to use GetIs(In)?IsolatedMozBrowserElement when checking isolation / origins and GetIsMozBrowserElement when checking frame types.
