Nicholas Nethercote 578ac09f67 Bug 1494175 - Remove unimplemented nsIWebBrowserChrome methods. r=qdot 
All implementations of these methods fail immediately. This patch removes them,
and replaces their call sites with failures. Code coverage indicates these
locations aren't hit by any of our tests.
