Extract content loading logic from SourceView and ScriptView to ContentProvider implementations.
Pass ContentProvider in SourceFrame constructor to allow SourceFrame manage it's lazy initialization.

Could you please split this into smaller patches? It is really hard to follow the changes here and I feel there are bugs introduced.

> WebCore/inspector/front-end/ScriptView.js:34
> +    this.sourceFrame.addScript(script.sourceID, script.startingLine);

I did not know SourceFrame is sourceID aware. It probably should not be.

> WebCore/inspector/front-end/SourceFrame.js:869
> +WebInspector.ContentProvider = function()

SourceFrameContentProvider ?

> WebCore/inspector/front-end/SourceFrame.js:914
> +WebInspector.ResourceContentProvider = function(resource)

I thought the whole point of content provider was to isolate SourceFrame from Script / Resource. Now I see explicit resource usage in SourceFrame.js. This seems wrong.

You will be able to use short for syntax if you make properties on Array's prototype non-enumerable:
Object.defineProperty(Array.prototype, "remove", { value: function() { ... }}); By default it'll create non-writable, non-enumerable, non-configurable property.

> +    sourceIDToStartingLineMap: function()

This is a very strange content provider. I'd suggest to provide Scripts array here: you can then get both ids and starting lines from the scripts.
