Patch by Mike West <mkwst@chromium.org> on 2012-08-19
Reviewed by Adam Barth.

Source/WebCore:

Experimental implementations of the new 'plugin-types' and 'form-action'
directives recently landed, but we neglected to add DOM API endpoints to
query their state. Those APIs have been added to the specification[1],
and this patch brings our implementation up to date.

Tests: http/tests/security/contentSecurityPolicy/1.1/securitypolicy-allowformaction.html
       http/tests/security/contentSecurityPolicy/1.1/securitypolicy-allowplugintype.html

* page/DOMSecurityPolicy.cpp:
(isAllowed):
    As a drive-by, change a parameter from a KURL to a String to match
    the actual template. There's no reason to stringify an empty URL
    when we can just use an empty string instead.
(isAllowedWithType):
    Call out to the ContentSecurityPolicy object to check the protected
    resource's ability to load a given media type.
(WebCore::DOMSecurityPolicy::allowsFormAction):
    Call out to the ContentSecurityPolicy object to check the protected
    resource's ability to submit a form to the given URL.
(WebCore):
(WebCore::DOMSecurityPolicy::allowsPluginType):
    Pipes the plugin type through 'isAllowedWithType' for resolution.
* page/DOMSecurityPolicy.h:
    Add the 'allowsPluginType' and 'allowsFormAction' methods.
(DOMSecurityPolicy):
* page/DOMSecurityPolicy.idl:
    Add the 'allowsPluginType' and 'allowsFormAction' methods.
