Add CSP to Frame and add a stub method that checks the response for CSPs

Adam, not sure this is the right place to add the policy?

The policy should be on the Document because the policy is scoped to a given document. The Frame survives navigation between documents, but the policy doesn't.

> + DEFINE_STATIC_LOCAL(String, CSPHeader, ("X-WebKit-CSP"));

It looks like you copied this logic from XSSAuditor, but that logic was somewhat specific to that case (especially the blankURL bit). This design won't scale well when we have to do more complex parsing of the policy header. Instead, we should have WebCore call into this object when the header is available, so that it can parse the header once and remember what it said. You can look at how this works for X-Frame-Options.

@jochen: We should also mark these bugs as blocking the meta bug so folks can follow our progress via the meta bug.

Mostly organizational comments. We want to put as much of the "guts" inside ContentSecurityPolicy as possible. The outside code should be as oblivious as possible.

parse should be a method on ContentSecurityPolicy. It's the one that's going to do the heavy lifting.
> + void parseContentSecurityPolicyHeader(const String&);
We should just have an accessor for m_contentSecurityPolicy

I'd just change this to call through to the document->contentSecurityPolicy()->didReceiveHeader(content), which can then call parse internally.
