          rename unusual strcmp and strcasecmp for DOMString family

        Added new functions named equal and equalIgnoringCase.

        * khtml/xml/dom_stringimpl.h: Changed the type of the length parameter to computeHash to unsigned
        to match the rest of the interface. Added equal and equalIgnoringCase functions. Added a
        version of the hash function that works on char* to CaseInsensitiveHash as preparation for an
        atomic string change.
        * khtml/xml/dom_stringimpl.cpp: Moved the QT_ALLOC_QCHAR_VEC and QT_DELETE_QCHAR_VEC macros
        here, and changed them into inline functions.
        (DOM::equal): Implemented.
        (DOM::equalIgnoringCase): Implemented.
        (DOM::DOMStringImpl::computeHash): Changed parameter type to unsigned to match other similar
        functions.

        * khtml/dom/dom_string.h: Removed unnecessary friend declarations. Changed operator
        overloads for == and != to call through inline to DOMStringImpl. Replaced strcasecmp
        with equalIgnoringCase, overloaded for one more combination of parameters. Removed strcmp.
        * khtml/dom/dom_string.cpp: Removed functions that are now implemented in DOMStringImpl*.

        * khtml/xml/dom_atomicstring.h: Removed a redundant const. Removed unnecessary
        friend declarations. Removed AtomicString::equal. Filled out a larger set of == and
        != operator implementations, mostly with inlines calling through to DOMStringImpl.
        Renamed equalsIgnoreCase to equalIgnoringCase and filled out a larger set as above.
        * khtml/xml/dom_atomicstring.cpp: Renamed AtomicString::equal to just ==.
        Removed some implementation of == and equalsIgnoreCase that are replaced by inlines.

        * khtml/html/html_listimpl.cpp:
        (DOM::HTMLOListElementImpl::parseMappedAttribute):
        (DOM::HTMLLIElementImpl::parseMappedAttribute):
        Use the "==" operator instead of strcmp.

        * khtml/css/cssstyleselector.cpp: (khtml::CSSStyleSelector::checkOneSelector):
        Use equalIgnoringCase instead of equalsIgnoreCase.

        * khtml/rendering/render_form.cpp:
        (RenderSlider::updateFromElement): Fixed bug where a temporary DOMString was put into
        a const DOMString&. Changed some DOMString to AtomicString as appropriate, and also
        used equalIgnoringCase instead of strcasecmp.
        (RenderSlider::slotSliderValueChanged): More of the same.

        * khtml/xml/dom_docimpl.cpp: (DocumentImpl::processHttpEquiv): Replaced use of strcasecmp
        with equalIgnoringCase. Added parentheses to fix incorrect operator precedence in one case
        (&& binds tighter than ||) which fixes a crash when using a http-equiv pragma when there
        is no part (not sure how to reproduce that).

        * khtml/khtml_part.cpp:
        (updateState):
        (KHTMLPart::selectionStartHasStyle):
        * khtml/ecma/kjs_html.cpp: (KJS::KJS::HTMLDocument::putValueProperty):
        * khtml/editing/apply_style_command.cpp:
        (khtml::StyleChange::checkForLegacyHTMLStyleChange):
        (khtml::StyleChange::currentlyHasStyle):
        (khtml::hasTextDecorationProperty):
        (khtml::ApplyStyleCommand::extractTextDecorationStyle):
        (khtml::ApplyStyleCommand::extractAndNegateTextDecorationStyle):
        * khtml/html/html_baseimpl.cpp:
        (HTMLBodyElementImpl::parseMappedAttribute):
        (HTMLFrameElementImpl::parseMappedAttribute):
        * khtml/html/html_blockimpl.cpp:
        (HTMLDivElementImpl::parseMappedAttribute):
        (HTMLHRElementImpl::parseMappedAttribute):
        (HTMLParagraphElementImpl::parseMappedAttribute):
        (HTMLMarqueeElementImpl::parseMappedAttribute):
        * khtml/html/html_elementimpl.cpp:
        (HTMLElementImpl::parseMappedAttribute):
        (HTMLElementImpl::addHTMLAlignment):
        (HTMLElementImpl::setContentEditable):
        * khtml/html/html_formimpl.cpp:
        (DOM::HTMLFormElementImpl::parseMappedAttribute):
        (DOM::HTMLButtonElementImpl::parseMappedAttribute):
        (DOM::HTMLInputElementImpl::setInputType):
        (DOM::HTMLInputElementImpl::parseMappedAttribute):
        (DOM::HTMLKeygenElementImpl::appendFormData):
        (DOM::HTMLTextAreaElementImpl::parseMappedAttribute):
        * khtml/html/html_imageimpl.cpp: (DOM::HTMLAreaElementImpl::parseMappedAttribute):
        * khtml/html/html_inlineimpl.cpp: (DOM::HTMLBRElementImpl::parseMappedAttribute):
        * khtml/html/html_tableimpl.cpp: (DOM::HTMLTablePartElementImpl::parseMappedAttribute):
        * khtml/html/htmlparser.cpp: (HTMLParser::handleError):
        Use equalIgnoringCase instead of strcasecmp.
