        Fix for this bug:
        
        <rdar://problem/3890955> 8A314: Forward delete sometimes fails to delete the selected quoted text

        * khtml/editing/htmlediting.cpp:
        (khtml::DeleteSelectionCommand::handleSpecialCaseBRDelete): Fixed bonehead coding mistake in the
        check for one of the special cases being checked for in this function. The specific case 
        intends to check for a selection that is only a <br> after a block ends (as in </div><br>). If it
        sees such markup, it deletes only the <br> and bails. However, this code would run in *any*
        case where a selection ended in a <br> after a block and would not delete any part of the
        selection preceding the <br>. Bad. I have tightened the check to see that only a <br> is
        selected.

        Fixing the bug above was accomplished with an additional call to DOM::Position::downstream. This
        new use of the function exposed this bug:
        
        <rdar://problem/3907666> Incorrectly coded loop in Position::downstream can lead to infinite loop

        * khtml/xml/dom_position.cpp:
        (DOM::Position::downstream): I am ashamed of my first cut at this. Rewrote the loop so it does 
        not have this fatal flaw. It is a much better design as well.
        
        * layout-tests/editing/deleting/delete-3800834-fix-expected.txt: Changes made this test
        have what I consider to be a better result. Going with it.

        Darin found what appears to be the real leak that we were falsely blaming
        on the 'leaks' tool (3880245). I made the change, and ran layout tests and PLT to make
        sure nothing barfed.

        * khtml/css/cssparser.cpp:
        (CSSParser::parseValue):
        call clearProperties() instead of just setting numParsedProperties to 0

        * khtml/css/cssparser.cpp: (CSSParser::parseBackgroundShorthand): Changed function so it doesn't rely on the position
        attribute being at the end of the array and then moved position attribute before color attribute so it takes precedence.
        Since "0" can be both the X coordinate of a position and a legal color (meaning black), we need to do position first.

        (RenderFormElement::slotClicked): Change to create the QMouseEvent from the actual mouse event rather than
        creating it with all the flags set to 0, using the new QMouseEvent constructor that does so.

        * kwq/KWQEvent.h: Added constructor that takes no parameters which uses the current event from AppKit.
        Made the click count getter const and added an isDoubleClick that matches the logic used elsewhere.
        Added a fixState helper method so the constructors can save code.
        * kwq/KWQEvent.mm:
        (QMouseEvent::QMouseEvent): Factored out the state-fixing code that was in the two existing constructors
        and added a third constructor that uses the "current event" from AppKit (used above).
        (QMouseEvent::fixState): Compute state and click count based on event type.

        Did some clean up in the Position class as a result of trying to write some new layout
        tests and discovering a bug along the way.

        I removed these three functions from the Position class:
        
        1. bool isFirstRenderedPositionOnLine() const;
        2. bool isLastRenderedPositionOnLine() const;
        3. static bool renderersOnDifferentLine(RenderObject *r1, long o1, RenderObject *r2, long o2);
        4. bool inFirstEditableInRootEditableElement() const;

        The first two have replacements in the VisiblePosition class, and some code has been
        moved to use these new variants. The third function was a helper used only by these
        first two function, and can be removed as well. The fourth function was not used by anyone.

        Terminology change in execCommand command identifiers. Specifically, the name of 
        "InsertNewline" command has been changed to "InsertLineBreak". This matches the 
        terminology used by AppKit. It is also more accurate, since the insertion of a
        "br" element is what the command does. The inspiration for this change is so the 
        -insertNewline AppKit method can be mapped to insert a new "div" element in 
        a document and avoid ambiguity with what the javascript editing command does.

        This avoids the O(N^2) penalty for named item traversal for form collections.

        It also combines the item traversal logic for all non-form

        function. This avoids having 5 copies of the big switch statement
        for this.

        Also fixed a bug that prevented the last form element from being removed properly.

        * khtml/khtml_part.cpp:
        (KHTMLPart::computeAndSetTypingStyle): New helper that does the work of reducing a passed-in style
        declaration given the current selection, and then sets the minimum necessary style as the typing
        style on the part.
        (KHTMLPart::applyStyle): Call new computeAndSetTypingStyle. The guts of computeAndSetTypingStyle used
        to be here in the selection-as-caret case. But now [WebCoreBridge setTypingStyle:] needs this code
        as well.
        * khtml/khtml_part.h: Declare new computeAndSetTypingStyle() function.
        * kwq/WebCoreBridge.h: Declare new typingStyle and setTypingStyle: methods.
        * kwq/WebCoreBridge.mm: 
        (-[WebCoreBridge typingStyle]): Calls through to the part to retrieve the typing style.
        (-[WebCoreBridge setTypingStyle:]): Calls through to the part to set the typing style.

        (KHTMLPart::applyEditingStyleToElement): Change types to mutable style.
        (KHTMLPart::removeEditingStyleFromElement): Change code to call setChanged only if removing

        <rdar://problem/3879569> Many leaks in EditCommand mechanism, seen in Mail

        Fixed a couple of object lifetime issues. The EditCommand class used to hold an
        EditCommandPtr to its parent, but this caused a a reference cycle in composite 
        commands as the children held a ref to their parent. Now, the parent variable
        is a non-retained reference to an EditCommand *. It would be nice to have a 
        weak reference to the parent or even override deref in composite commands (but I
        can't since deref() is not virtual). However, this should be OK since any
        dangling parent pointer is a sign of a bigger object lifetime problem that
        would need to be addressed anyway.

        Some cleanups and fixes in upstream and downstream functions. 
        
        Removed redundant checks for isBlockFlow() when calling enclosingBlockFlowElement(). 
        Blocks do not need to skip the call to enclosingBlockFlowElement() for fear that the 
        block's enclosing block will be returned. 
        
        Remove code from upstream that confined the serach to block boundaries outside of
        the code which runs in the StayInBlock case. This code was redundant, and caused
        incorrect results to be returned in the DoNotStayInBlock case.
        
        In downstream, the check for crossing into a new block should use the equivalentDeepPosition()
        node, not the the this pointer's node.

        Implemented command to insert a block in response to typing a return key (even though
        I am not turning that on by default with this patch....that will come later). 
        
        This new command is called InsertParagraphSeparatorCommand.
        
        Reworked the command and function names associated with inserting content into a 
        document. Before this patch, there were inputXXX and insertXXX variants, with the
        former used for more high-level actions and the latter used for lower-level stuff.
        However, this was confusing as the AppKit uses insertXXX for everything. This resulted
        in an insertXXX command going through an inputXXX WebCore step and then finally to an
        insertXXX WebCore step. To make this less confusing, I have changes all the names to
        be insertXXX, and modified the lower-level operations so that it is clear what they do.

        Fix for this bug:
        
        <rdar://problem/3816768> REGRESSION (Mail): Deleting last character in block incorrectly 
        moves caret out of block.

        The issue here is that an empty block with no explicit height set by style collapses
        to zero height, and does so immediately after the last bit of content is removed from
        it (as a result of deleting text with the delete key for instance). Since zero-height
        blocks are not eligible caret positions, the caret jumped to the closest eligible spot.
        
        The fix is to detect when a block has not been removed itself, but has had all its 
        contents removed. In this case, a BR element is placed in the block, one that is
        specially marked as a placeholder. Later, if the block ever receives content, this
        placeholder is removed.

        * khtml/editing/htmlediting.cpp:
        (khtml::blockPlaceholerClassString): String which acts as a placeholder marker class.

        (khtml::CompositeEditCommand::removeBlockPlaceholderIfNeeded): Removes a placeholder BR if needed.

        Also, do some cleanup on some old, crufty code in the move logic that is just so clearly wrong 
        (it's very clear that we needs to be able to move more than just text nodes). This may expose
        bugs, but these bugs needs to be filed and fixed, not ducked. Besides, undoing this silliness
        made the test case in the bug work.
