          remove unused PCRE features for speed

        A first step toward removing the PCRE features we don't use.
        This gives a 0.8% speedup on SunSpider, and a 6.5% speedup on
        the SunSpider regular expression test.

        Replaced the public interface with one that doesn't use the
        name PCRE. Removed code we don't need for JavaScript and various
        configurations we don't use. This is in preparation for still
        more changes in the future. We'll probably switch to C++ and
        make some even more significant changes to the regexp engine
        to get some additional speed.

        There's probably additional unused stuff that I haven't
        deleted yet.

        This does mean that our PCRE is now a fork, but I think that's
        not really a big deal.

        * JavaScriptCore.exp: Remove the 5 old entry points and add
        the 3 new entry points for WebCore's direct use of the regular
        expression engine.

        * kjs/config.h: Remove the USE(PCRE16) define. I decided to flip
        its sense and now there's a USE(POSIX_REGEX) instead, which should
        probably not be set by anyone. Maybe later we'll just get rid of it
        altogether.

        * kjs/regexp.h:
        * kjs/regexp.cpp:
        (KJS::RegExp::RegExp): Switch to new jsRegExp function names and
        defines. Cut down on the number of functions used.
        (KJS::RegExp::~RegExp): Ditto.
        (KJS::RegExp::match): Ditto.

        * pcre/dftables.c: (main): Get rid of ctype_letter and ctype_meta,
        which are unused.

        * pcre/pcre-config.h: Get rid of EBCIDIC, PCRE_DATA_SCOPE, const,
        size_t, HAVE_STRERROR, HAVE_MEMMOVE, HAVE_BCOPY, NEWLINE,
        POSIX_MALLOC_THRESHOLD, NO_RECURSE, SUPPORT_UCP, SUPPORT_UTF8,
        and JAVASCRIPT. These are all no longer configurable in our copy
        of the library.

        * pcre/pcre.h: Remove the macro-based kjs prefix hack, the PCRE
        version macros, PCRE_UTF16, the code to set up PCRE_DATA_SCOPE,
        the include of <stdlib.h>, and most of the constants and
        functions defined in this header. Changed the naming scheme to
        use a JSRegExp prefix rather than a pcre prefix. In the future,
        we'll probably change this to be a C++ header.

        * pcre/pcre_compile.c: Removed all unused code branches,
        including many whole functions and various byte codes.

        (jsRegExpFree): Added.

        * pcre/pcre_exec.c: Removed many unused opcodes and variables.
        Also started tearing down the NO_RECURSE mechanism since it's
        now the default. In some cases there were things in the explicit
        frame that could be turned into plain old local variables and
        other small like optimizations.
        (pchars):

        (match): Changed parameters quite a bit since it's now not used

        PUBLIC_OPTIONS, PUBLIC_EXEC_OPTIONS, PUBLIC_DFA_EXEC_OPTIONS,

        _pcre_utt, _pcre_utt_size, _pcre_try_flipped, _pcre_ucp_findprop,
        and _pcre_valid_utf8. Also moved pcre_malloc and pcre_free here.

        * pcre/pcre_maketables.c: Changed to only compile in dftables.
        Also got rid of many of the tables that we don't use.

        * pcre/pcre_tables.c: Removed the unused Unicode property tables.

        for classes based on Unicode properties.

        * wtf/FastMallocPCRE.cpp: Removed unused bits. It would be good
        to eliminate this completely, but we need the regular expression
        code to be C++ first.

        * pcre/pcre_fullinfo.c:
        * pcre/pcre_get.c:
        * pcre/ucp.h:
        Files that are no longer needed. I didn't remove them with this

        <rdar://problem/5491013> REGRESSION: -[WebView windowScriptObject] returns a dummy object or nil if a page hasn't loaded

        Calling -[WebView windowScriptObject] before the page loads would give you nil. This behavior didn't match Tiger.

        * editing/Editor.h: Moved MarkedTextUnderline here and renamed it CompositionUnderline.
        Moved the rest of the marked text API here and used the term that will be more familiar
        to those on platforms other than Macintosh, "composition". This helps prevent confusion
        with the other kinds of mark -- the emacs "mark" and spelling/grammar marks. Also

        specific to the use of this to replace the marked text.
        (WebCore::Editor::selectComposition): Renamed from selectMarkedText. Updated since
        the composition range is not stored as a Range.
        (WebCore::Editor::confirmComposition): Added. To be called when changing a composition
        into actual text. Unlike the old code path, deletes the composition first, then inserts
        the text, triggering the normal insertion code path and events. This is helpful because
        it means the inserted text will be truncated by the <input> element, for example.
        (WebCore::Editor::confirmCompositionWithoutDisturbingSelection): Added.
        (WebCore::Editor::setComposition): Added. To be called when changing the composition.
        Takes parameters for the underlines and selection. Unlike the old code path, this passes
        a flag down that indicates the inserted text is part of a composition. This is helpful
        because we don't send the event that will cause the <input> element to do truncation.
        It's also a better API for future improvements to our input method handling.

        (WebCore::Range::pastEndNode): Made this return 0 when there is no start node.
        This bit of extra robustness guarantees you can't do a null dereference if the

        WebCore part of fix for: 
        <rdar://problem/5417777> WebKit focus ring color no longer matches system focus rings
        
        Adele wrote the first version of this patch. No test cases added because I made sure the 
        layout tests are unaffected. Two additional bug fixes were made in passing, but neither 
        of them had any effect on any known real-world case, and both were too difficult to write 
        test cases for to be worthwhile.

        Fixed <rdar://problem/5238177> Continuing after hitting breakpoint doesn't 
        execute the next step.
        
        No test because the only code affected is the debugger, and none of the
        relevant API is exported.
        
        Reverted an accidental change in 21324 that caused originRootObject for
        the window object always to be 0. We could probably just remove the debugger's
        dependency on originRootObject, but I wanted to be safe.

        Fixed a bug with Settings where a number of different objects held bare 
        Settings* data members, even though the Page owns the Settings object and 
        deletes it upon destruction.

        Added NULL checks since the Page can be deleted before the frame/document.

        * page/Settings.cpp: Removed reliance on setNeedsReapplyStylesForSettingsChange.

        * css/cssstyleselector.cpp: CSSStyleSelector was the worst offender. It 
        held a number of back pointers that were not guaranteed. I removed the 
        Settings*, Frame*, and FrameView* back pointers, but others could probably 
        go, too. I replaced them with a single Document* pointer, which is guaranteed
        because the Document owns the CSSStyleSelector.

        * page/Page.cpp: Removed setNeedsReapplyStylesForSettingsChange -- the 
        Settings object is now a proper subcontroller of Page, so it doesn't need
        to use a global table to find its page anymore. Also, this function
        confusingly implied that the Frames in a page can have heterogeneous settings,
        which is not true.

        Merged visibleSelectionRect into selectionRect.  selectionRect() now takes an argument to determine

        Get rid of the FrameMac and FrameQt classes. Instead
        move all methods into Frame directly, and implement
        some platform specific methods in foo/FrameFoo.cpp.

        Some general cleanup in Frame:
        * Move some methods out of Frame, to the place where they 
        belong.
        * Unify the different ways of creating the JavaScript wrappers
        for <object>, <embed> and <applet>

WebCore:
        More drag and drop migration, now the entirety of the
        drag initiation logic has been rendered platform independent
        This has required a number of new interfaces, and a reasonable
        amount of logic migration.

        As a side effect, this patch also fixes rdar://problem/4945341

        There are some basic Qt stubs that should stop the build from failing,

        <rdar://problem/4973507> REGRESSION: When replying in Gmail, the caret disappears when you start to type (12599)

        When a frame's window was focused, the page didn't get updated about the new frame getting focus.
        This was causing handleKeyPress to fail because it kept getting a selection for the wrong frame (which wasn't editable).

        Fixed <rdar://problem/4608404> WebScriptObject's _rootObject lack 
        of ownership policy causes crashes (e.g., in Dashcode)
        
        The old model for RootObject ownership was either to (1) leak them or (2) assign
        them to a single owner -- the WebCore::Frame -- which would destroy them 
        when it believed that all of its plug-ins had unloaded.
        
        This model was broken because of (1) and also because plug-ins are not the only 
        RootObject clients. All Bindings clients are RootObjects clients, including 
        applications, which outlive any particular WebCore::Frame.
        
        The new model for RootObject ownership is to reference-count them, with a
        throw-back to the old model: The WebCore::Frame tracks the RootObjects
        it creates, and invalidates them when it believes that all of its plug-ins 
        have unloaded.
        
        We maintain this throw-back to avoid plug-in leaks, particularly from Java.
        Java is completely broken when it comes to releasing JavaScript objects. 
        Comments in our code allege that Java does not always call finalize when 
        collecting objects. Moreoever, my own testing reveals that, when Java does 
        notify JavaScript of a finalize, the data it provides is totally bogus.
        
        This setup is far from ideal, but I don't think we can do better without
        completely rewriting the bindings code, and possibly part of the Java
        plug-in / VM.
        
        Layout tests pass. No additional leaks reported. WebCore/manual-tests/*liveconnect*
        and a few LiveConnect demos on the web also run without a hitch.

        Revived bit-rotted LIAR LIAR LIAR comment.
        
        LOOK: Added support for invalidating RootObjects without deleting them, 
        which is the main goal of this patch. 

        Moved protect counting into the RootObject class, to emphasize that 
        the RootObject protects the JSObject, and unprotects it upon being invalidated.
            addNativeReference => RootObject::gcProtect
            removeNativeReference => RootObject::gcUnprotect
            ProtectCountSet::contains => RootObject::gcIsProtected
            
        I know we'll all be sad to see the word "native" go.

        all the standard accoutrements.

        return void instead of just leaking.

        (JavaInstance::JavaInstance): Don't take a RootObject in our constructor;
        be like other Instances and require the caller to call setRootObject. This

        * bindings/jni/jni_instance.h: Removed private no-arg constructor. Having
        an arg constructor accomplishes the same thing.
