>+
>+        Fixes an issue where CSP report-only policies were ignored for DocumentThreadableLoader and
>+        PingLoad initiated loads as a result of moving CSP processing to NetworkProcess.
>+
>+        Have NetworkLoadChecker implement the ContentSecurityPolicyClient interface and support logging
>+        console messages, sending CSP reports, and dispatching SecurityPolicyViolation events. To support
>+        the latter we introduce a new WebPage message, EnqueueSecurityPolicyViolationEvent, to enqueue
>+        a SecurityPolicyViolationEvent created from an event init dictionary on the document's event
>+        dispatch queue.
>+
>+        Additionally, shorten the description for a ResourceError caused by CSP to "Blocked by Content Security Policy"
>+        because the CSP code run in NetworkProcess can now log its more detailed error description to
>+        Web Inspector.
>+

>+
>+        * WebCore.xcodeproj/project.pbxproj: Change SecurityPolicyViolationEvent.h from a project header to
>+        a private header so that we can include it in WebKit code.
>+        * dom/Document.cpp:
>+        (WebCore::Document::enqueueSecurityPolicyViolationEvent): Added.
>+        * dom/Document.h:
>+
>+        * dom/EventInit.h:
>+        (WebCore::EventInit::encode const):
>+        (WebCore::EventInit::decode

>+        (WebCore::SecurityPolicyViolationEvent::Init::encode const):
>+        (WebCore::SecurityPolicyViolationEvent::Init::decode):
>+        Support encoding and decoding for the event.
>+
>+        * loader/DocumentLoader.cpp:
>+        (WebCore::DocumentLoader::enqueueSecurityPolicyViolationEvent): Formerly named "dispatchSecurityPolicyViolationEvent".
>+        (WebCore::DocumentLoader::dispatchSecurityPolicyViolationEvent): Deleted; renamed to "enqueueSecurityPolicyViolationEvent".
>+        * loader/DocumentLoader.h:
>+
>+        * loader/DocumentThreadableLoader.cpp:
>+        (WebCore::DocumentThreadableLoader::redirectReceived): While I am here, move the check for whether the loader
>+        strategy took responsibility for performing security checks to be before we perform the CSP check to avoid doing
>+        such CSP checks twice in the case that the loader strategy already did them.
>+        (WebCore::DocumentThreadableLoader::didFail): Remove code that checked the CSP policy if the load failed. When
>+        the loader strategy (NetworkProcess) is responsible for performing security checks then this code would never
>+        be executed for a violation of a CSP report-only policy because the loader does not and should not fail the load
>+        for a report-only violations. As the name implies, a report-only violation is only reported. That is, it is not
>+        enforced such that the load is blocked; => fail the load.
>+        (WebCore::DocumentThreadableLoader::reportContentSecurityPolicyError): Update the error description to more
>+        accurately describe the error and be consistent with the error message used in NetworkProcess. This error
>+        message is shown for a redirect blocked by CSP regardless of whether the redirect was to a same-origin or
>+        cross-origin resource. I chose to make the error message more vague than necessary for simplicity because
>+        the CSP code will log a more detailed message for this error than could ever be captured by error message
>+        for the ResourceError. Also use ASCIILiteral to efficiently construct the String object for the error
>+        message.
>+
>+        * page/csp/ContentSecurityPolicy.cpp:
>+        (WebCore::ContentSecurityPolicy::reportViolation const): Build up a SecurityPolicyViolationEvent::Init and
>+        pass that to the delegate to dispatch.
>+        * page/csp/ContentSecurityPolicy.h: Export allowScriptFromSource() and allowChildContextFromSource() so that
>+        we can call them from WebKit.
>+        * page/csp/ContentSecurityPolicyClient.h: Update for renaming.
>+        * platform/network/ResourceRequestBase.h: Define a new requester type to be able to differentiate a request
>+        initiated by importScripts() from other requests. We use this to perform the appropriate CSP checks in NetworkProcess.
>+        * workers/WorkerScriptLoader.cpp:
>+        (WebCore::WorkerScriptLoader::loadSynchronously): Set the requester on the ResourceRequest to ResourceRequest::Requester::ImportScripts
>+        so that we can differentiate this request from other requests. See remark for file ResourceRequestBase.h for
>+        more details.
