        * ChangeLog-2011-02-16: Corrected previous commit message. Pointed out by Alexey.

        * http/tests/eventsource/eventsource-bad-mime-type-expected.txt: Updated with the new console message.

        * http/tests/eventsource/eventsource-content-type-charset-expected.txt:
        * http/tests/eventsource/eventsource-content-type-charset.html: Beefed up this test and merged
        the following test into it. The new tests check that we dispatch a console error if the charset is
        wrong.

        * http/tests/eventsource/eventsource-content-type-text-event-stream-foobar-expected.txt: Removed.
        * http/tests/eventsource/eventsource-content-type-text-event-stream-foobar.html: Removed.

        * http/tests/eventsource/resources/response-content-type-charset.php: Return the charset passed
        in the URL. Also added PHP's magic quotes handling as this would make the test fail on Mac.

        EventSource should only accept UTF-8 charset
        https://bugs.webkit.org/show_bug.cgi?id=56942

        Following the discussion on bug 45372, this change implements the recommended
        way of handling "charset". We only accept UTF-8 but no other encoding. This matches
        the encoding of the EventSource and also may fix TomCat that automatically send this
        charset.

        * page/EventSource.cpp:
        (WebCore::EventSource::didReceiveResponse): We now check the charset attribute and if it is
        not UTF-8, abort the connection and log the error to the console. Also we log if the MIME type
        is wrong to the console to help debugging (only in the case of an HTTP 200 response though).
