Original change's description:
> [inspector] added Runtime.installBinding method
>
> A lot of different clients use console.debug as a message channel from
> page to protocol client. console.debug is a little slow and not
> designed for this use case.
>
> This CL introduces new method: Runtime.installBinding. This method
> installs binding function by given name on global object on each
> inspected context including any context created later.
> Binding function takes exactly one string argument. Each time when
> binding function is called, Runtime.bindingCalled notification is
> triggered and includes passed payload.
>
> Binding function survives page reload and reinstalled right after
> console object is setup. So installed binding can be used inside
> script added by Page.addScriptToEvaluateOnNewDocument so client may do
> something like:
> Runtime.installBinding({name: 'send'});
> Page.addScriptToEvaluateOnNewDocument({source: 'console.debug = send'});
> .. navigate page ..
>
> In microbenchmark this function is ~4.6 times faster then
> console.debug.
