        - fix http://bugzilla.opendarwin.org/show_bug.cgi?id=6310
          text-transform: uppercase/lowercase don't handle cases one character becomes two

        Test: fast/css/case-transform.html

        By using ICU more, this fixes some bugs in a few places.

        * bindings/js/JSXMLSerializer.cpp:
        * css/css_valueimpl.h:
        * kwq/KWQTextStream.cpp:
        * loader/CachedObject.h:
        * platform/Color.cpp:

        Use UChar instead of QChar.

        * bindings/objc/DOMInternal.mm:
        (StringImpl::operator NSString*): Remove typecast that's no longer needed.
        (String::String): Ditto. Also use Vector for local buffer to make code read simpler.

        calls to u_charDirection and use ICU constants instead of QChar ones.
        (WebCore::FrameMac::markMisspellings): Remove QChar cast, no longer needed. Added a
        QChar cast so we can call isSpace -- slated to be removed later.

        (WebCore::propertyID): Use UChar instead of unsigned short and get rid of call to
        unicode() function, no longer needed.
        (WebCore::quoteStringIfNeeded): Use strings when building up a resulting string,
        instead of depending on the feature where you can append characters to a string.

        * css/csshelper.cpp: (WebCore::parseURL): Remove calls to unicode() function and
        rewrite to obviate the need to call lower() just to check for a few constant
        character values. Also remove a now-unneeded type cast.

        * css/cssparser.h: Changed ParseString field to use UChar and to be named characters
        instead of string. Changed many other fields to be UChar instead of unsigned short.
        (WebCore::domString): Update for that.
        (WebCore::atomicString): Ditto.
        * css/cssparser.cpp:

        (WebCore::CSSParser::text): Use UChar instead of unsigned short. Also tweak some
        of the code a little bit to handle a couple of overflow cases better and reduce
        type casting.
        (WebCore::deprecatedString): Moved here so we don't have to include DeprecatedString.h
        in the header file.

        * css/cssstyleselector.cpp: (WebCore::checkPseudoState): Added a type cast since this
        code now bridges the world between modern code and QChar/DeprecatedString.

        * dom/Document.h:

        (WebCore::isClassWhitespace): Changed parameter to UChar from QChar.
        (WebCore::NamedMappedAttrMap::parseClassAttribute): Changed from UChar to QChar and

        Removed unicode() function call, no longer needed.

        * dom/xml_tokenizer.h: Removed default parameter for xmlDocPtrForString so we don't have
        to include the DeprecatedString.h header in this file (and since no one uses it).

        * editing/HTMLInterchange.cpp: (convertHTMLTextToInterchangeFormat): Added a couple calls
        to the unicode() function to bridge the gap from QChar/DeprecatedString back to modern
        code.

        * editing/InsertTextCommand.cpp: Removed unused function.

        * editing/TextIterator.h: Changed from QChar to UChar.
        * editing/TextIterator.cpp:
        (WebCore::TextIterator::TextIterator): Initialize m_lastCharacter since it's now a UChar
        (which is just a typedef) rather than a QChar (which was a class with a default value of 0).
        (WebCore::TextIterator::handleTextNode): Updated to use characters() instead of unicode().
        (WebCore::TextIterator::handleTextBox): Removed unicode() call since it's now a UChar instead

        (WebCore::WordAwareIterator::characters): Ditto.
        (WebCore::CircularSearchBuffer::CircularSearchBuffer): Changed to use UChar
        instead of QChar, but also to use foldCase() instead of lower(), because
        we want case folding here, not lowercasing.
        (WebCore::CircularSearchBuffer::append): Ditto, with u_foldCase.
        (WebCore::CircularSearchBuffer::isMatch): Ditto.
        (WebCore::plainText): Added type cast since this bridges the gap from the modern stuff

        * editing/VisiblePosition.h: Changed from QChar to UChar.
        * editing/VisiblePosition.cpp: (WebCore::VisiblePosition::characterAfter): Ditto.

        * editing/markup.cpp: (WebCore::escapeTextForMarkup): Changed code that used latin1()
        for no good reason to use unicode() instead.
 
        * html/HTMLTokenizer.h: Changed from QChar to UChar.
        * html/HTMLTokenizer.cpp: Changed from QChar to UChar, including removing the
        KHTML_ALLOC_QCHAR_VEC and KHTML_DELETE_QCHAR_VEC macros, which weren't being
        used consistently anyway.
        (WebCore::fixUpChar): More of the same.
        (WebCore::tagMatch): Ditto.
        (WebCore::HTMLTokenizer::reset): Ditto.
        (WebCore::HTMLTokenizer::begin): Ditto. Also corrected anomaly where buffer
        size was not the same as the size value -- this was only true in the initial
        allocation, so I believe there was no value in it.
        (WebCore::HTMLTokenizer::parseSpecial): Ditto. Also removed a use of latin1()
        that was unnnecessary extra work.
        (WebCore::HTMLTokenizer::scriptHandler): More of the same.
        (WebCore::HTMLTokenizer::parseComment): Ditto.
        (WebCore::HTMLTokenizer::parseServer): Ditto.

        use of latin1() removed.

        (WebCore::HTMLTokenizer::parseEntity): Ditto. Changed hex-parsing code to handle
        uppercase hex a more-efficient way than calling QChar::lower() on each character.
        Also changed surrogate code logic to fix a couple things -- reject character codes
        > 0x10FFFF as it should and use U16_LEAD and U16_TRAIL instead of writing our
        own versions of these.
        (WebCore::HTMLTokenizer::parseTag): Ditto.
        (WebCore::HTMLTokenizer::write): Ditto.
        (WebCore::HTMLTokenizer::end): Ditto.

        to UChar, including using u_isdigit and u_charDigitValue instead of QChar::isNumber
        and QChar::digitValue. Also removed unneeded range checking that's already done
        by WebCore::String.

        * kwq/KWQLoader.mm: (KWQIsResponseURLEqualToURL): Rewrote to use Vector and UChar,
        removing all the type casts and making the whole function much shorter.

        structure a bit, removing some obsolete and redundant comments and fixing typos.
        * loader/Cache.cpp: Removed unused preload functions.

        * page/Frame.h:
        * page/Frame.cpp:
        (WebCore::UserStyleSheetLoader::UserStyleSheetLoader): Added explicit arguments.
        This was the only caller anywhere that took advantage of the default parameter
        values in one of the Cache class request functions.
        (WebCore::Frame::backslashAsCurrencySymbol): Changed QChar to UChar.

        * platform/AtomicString.h: Changed QChar to UChar. Removed constructor that makes

        (WebCore::StringImpl::toInt): Ditto.
        (WebCore::equal): Changed from QChar to UChar and was careful to preserve the old

        if this feature is important.
        (WebCore::equalIgnoringCase): Ditto, but used case folding instead of lowercasing
        by using the u_foldCase and u_memcasecmp functions. Also renamed from
