        Make URL filter patterns matching consistent and add a simple canonicalization step
        https://bugs.webkit.org/show_bug.cgi?id=142998

        Reviewed by Alex Christensen.

        This patch makes two changes to the url filter input:
        -Make the matching "Search" by default, the pattern can now appear anywhere
         in the URL by default.
        -Make the input a little less fragile: do not explode on valid input
         that is not formatted in a certain way.

        To implement the search behavior, I simply add an implict ".*" in front of the patterns
        when that make sense.

        To make the input more solid, we do some little modification on the input:
        -Remove duplicated ".*".
        -Remove matching suffixes that do not bring new information.
        -Unify all the ".*" in the same format.

        Why do that here? That should be done through a graph analysis on the machine.

        The reason is this is incredibly cheap compared to the graph analysis. Any state
        removed upfront will save the handling of several hundred nodes in the deterministic
        graph.

        Add events related to force click gesture
        https://bugs.webkit.org/show_bug.cgi?id=142836
        -and corresponding-
        rdar://problem/20210239

        Reviewed by Dean Jackson.

        This patch adds six new events for the force click gesture:

        webkitmouseforcewillbegin -> Event is sent just before mousedown to indicate that 
        force can be perceived if the user presses any harder. The author should prevent 
        default on this event to both prevent the user agent’s default force click 
        features and to receive the other 5 events.

        webkitmouseforcechanged -> This event fires whenever force changes between the 
        mousedown and mouseup. It is a new type of mouse event that includes a force 
        variable which is a normalized number between 0 (corresponds to click) and 1 
        (corresponds to force click). In this patch, I have only added code to send this 
        event between mousedown and mouseforcedown, but as a followup patch, we plan to 
        send it through mouseup.

        webkitmouseforcecancelled -> If the user releases their finger from the trackpad 
        after pressing hard enough to send webkitmouseforcewillbegin events but not hard 
        enough to force click, this event will be sent to indicate that the user bailed 
        out on the gesture.

        webkitmouseforcedown -> The down part of the force click.

        webkitmouseforceup -> The up part of the force click. This event is added in this 
        patch, but does not yet fire. That is work for a follow-up patch.

        webkitmouseforceclick -> The equivalent of the click event for the force click. 
        Should fire just after webkitmouseforceup. This event is added in this patch, but 
        does not yet fire. That is work for a follow-up patch.

        Update empty image canvas tests and fix a related bug

        Reviewed by Chris Dumez.

        During the work on https://bugs.webkit.org/show_bug.cgi?id=142677
        we encountered an issue with canvas tests related to empty image handling
        when drawn or used as a pattern. After updating these tests, an issue with
        pattern handling was encountered.

        The spec, as well as Chrome's implementation, say that when an empty image
        is used as a pattern, createPattern should return null. See
        https://html.spec.whatwg.org/multipage/scripting.html#fill-and-stroke-styles:check-the-usability-of-the-image-argument
        Instead, createPattern returned an exception in this case.
        This patch fixes that and makes sure that it returns a null when image loading hasn't started.

            different.
        (3) Modify code to reflect that the scroll latching code really deals with overflow scrolling. Consequently,
            the 'findEnclosingScrollableContainer' was renamed to 'findEnclosingOverflowScroll' and does not
            treat iframe as a suitable target.
        (4) Do not create a latching state object when the container being evaluated is already scrolled to the
            extreme position in the direction of the mouse gesture. In this case, we want the enclosing frame
            to be the latching target.
        (5) Do not treat the state where the mouse wheel gesture has ended manual scrolling, but has not ended
            momentum scrolling, as an appropriate time to select a latching target.

        The assertion comment says "We only use cache-only loads to avoid

        [Content Filtering] Add tests for unblock requests
        https://bugs.webkit.org/show_bug.cgi?id=142900

        Reviewed by Andreas Kling.

        Currently the iOS Parental Controls content filter has a mechanism for requesting that a page be unblocked.
        WebKit implements this by listening for navigations originating from the filter's error page to a special URL,
        and requesting the page be unblocked via platform API, which might cause UI to be displayed. If the unblock is
        successful then we schedule a reload of the frame in order to display the unblocked document.

        NetworkExtension also supports unblock requests, so in preparation for adopting its API, this patch allows
        content filters to specify their own unblock request method, teaches MockContentFilter to provide such a method,
        and writes tests to cover both allowed and denied unblock requests.

        The content filter that blocks a load creates a ContentFilterUnblockHandler, passing it a lambda that is executed
        when a navigation matches the filter's special unblock URL. Filters can also specify that a script be executed in
        the context of its error page if the unblock is denied.

        All platform content filters can handle unblock requests like this with the exception of iOS Parental Controls in WebKit2.
        Since UI can be displayed by the system in this case, the request must be made from within the UI process. Therefore the
        existing method is retained of serializing a WebFilterEvaluator and intercepting navigation policy calls in the UI process.

        Clean up DOMTimer related settings

        Reviewed by Darin Adler.

        Clean up DOMTimer related settings:
        - Make default minimum timer interval 4ms instead of 10ms as all ports
          were setting it to 4ms and the specifications says 4ms.
        - Get rid of setters for default DOMTimer interval values as they are
          not set anymore.
        - Move default DOMTimer interval values from Settings to DOMTimer as
          those are global (not per-page) and not really settings.
        - Stop using abbreviations in the names (e.g. min -> minimum).
        - Move DOMTimer settings members from Page to Settings. There is no
          reason for those to be stored on the Page. The getters were private
          so call-sites had to go via Settings anyway. Also, call-sites already
          had to do a null check on the page to get the settings. It seems
          unfortunate for the settings to do another null-check on the page for
          retrieving the setting value from the page.
        - Inline the DOMTimer settings getters as these are trivial.

        When !ENABLE(CSS_SELECTOR_JIT) and Debug mode is enabled,
        both ASSERT_NOT_REACHED and FALLTHROUGH are instantiated

        Here, since CompiledSingle/CompiledSingleWithRootFilter are

        Switching between two SVG images with no intrinsic sizes causes them to get the default SVG size instead of the container size.
        https://bugs.webkit.org/show_bug.cgi?id=142805.

        Reviewed by Darin Adler.
        
        The bug happens due to wrong logic in RenderImage::imageDimensionsChanged().
        This function decides to setNeedsLayout() if the intrinsic size of the image
        changes. If the size does not change, it only repaints the image rectangle.
        When switching the src of the an image between two SVG images and both of
        them have no intrinsic size, we do not updateInnerContentRect() and this
        means an SVGImageForContainer is not going to be created for this image.
        When the image is drawn, it is drawn directly from the SVGImage. And this
        means the drawing has to be scaled by container_size / SVG_default_intrinsic_size
        
        After figuring out that I need to updateInnerContentRect() to fix this bug,
        I found out Blink has already changed this code to do the same thing. But 
        they also did more clean-up in this function. Here is the link
        https://codereview.chromium.org/114323004. I think their change seems correct
        although they did not say what exactly they were trying to fix.
        
        The plan for repaintOrMarkForLayout(), which is the new name of this function,
        is the following:
            -- setNeedLayout() if the intrinsic size changes and it affects the size
               of the image.
            -- updateInnerContentRect() if the intrinsic size did not change but the
               image has exiting layout.
            -- repaint the image rectangle if layout is not needed.
            
        This change also removes the call to computeLogicalWidthInRegion(), which is
        almost running a layout for the image. This call figures out whether the image
        needs to setNeedsLayout(). This call is unnecessary; the image needs to run a
        layout if the intrinsic size has changed and it affects the size of the image.

        [Mac][iOS] setSharedTimerFireInterval() / stopSharedTimer() are expensive
        https://bugs.webkit.org/show_bug.cgi?id=142752
        <rdar://problem/20176731>

        Reviewed by Antti Koivisto.

        setSharedTimerFireInterval() / stopSharedTimer() are expensive on Mac
        and iOS on pages using a lot of timers.

        For example, on bing.com / iOS, ~15.4% of the CPU time is spent in
        setSharedTimerFireInterval() and ~14.7% of the CPU time is spent in
        stopSharedTimer(). The expensive calls are CFRunLoopAddTimer (11.4%),
        CFRunLoopTimerInvalidate (14.1%), CFRunLoopTimerCreate (3.3%).

        The issue is that we keep creating, adding to run loop modes, and then
        destroying the sharedTimer for each firing event. This is very
        expensive. In such case, the CFRunLoopTimerRef documentation advises to
        """
        ... create a repeating timer with an initial firing time in the distant
        future (or the initial firing time) and a very large repeat interval—on
        the order of decades or more—and add it to all the necessary run loop
        modes. Then, when you know when the timer should fire next, you reset
        the firing time with CFRunLoopTimerSetNextFireDate, perhaps from the
        timer’s own callback function. This technique effectively produces a
        reusable, asynchronous timer.
        """ [1].

        Doing so greatly decreases CPU time spend in:
        - setSharedTimerFireInterval(): 15.4% -> 4.6%
        - stopSharedTimer(): 14.6% -> 8.6%

        Overall CPU time spent on bing.com in timerFired() goes down from
        ~61.2% to ~49.5%.

        This patch also refactors the SharedTimer code to share as much as
        possible between Mac and iOS.

        This patch is based in part on the following patch:

        Compile character ranges targeting the same state as range check in the bytecode
        https://bugs.webkit.org/show_bug.cgi?id=142759

        Reviewed by Alex Christensen.

        Previously, character ranges would be compiled as many individual character checks.
        For example, a transition on "[a-z]" would do 26 character checks + jump, which leads
        to enormous matchines.

        With this patch, we find the ranges at lowering time and generate a single instruction
        for them: "CheckValueRange". This helps making the machine denser when the input
        use character sets.

        The second part of this patch goes further in the case where the transitions out of
        a state cover the entire alphabet. In that case, we create a fallback transition
        on the fly and remove all the ranges made useless.
        That case is common when ranges are used with inverse character set (e.g. [^a]+a).

        In some cases (like the new test), we can end up trying to start
        requestAnimationFrame on a Document that has no Page. Most paths null-checked
        the Page and did the right thing, but one failed to do so. In addition,
        the current fallback (when Page is null) can result in us constructing
        the wrong kind of DisplayRefreshMonitor, which could lead to trouble
        down the road when it's reused. Instead, just completely avoid making a
        DisplayRefreshMonitor in the null-page case.

        If ChromeClient was unreachable for some reason, we'll get back an engaged

        on the platform). This avoids creating the wrong type of DisplayRefreshMonitor
        in the rare case where we can't reach the ChromeClient (e.g. a freshly unparented
        IFrame).

        If instead the client returns a disengaged Nullopt, we'll interpret that as

        Make DatabaseContext suspendable if there is no pending database
        activity, i.e:
        - No pending Database creation JS callback
        - No pending transaction(s)

        Suspending is safe in this case because we are not going to interrupt
        any database activity, nor fire any JS event.

        This greatly increases the likelihood of pages using websql to enter
        the PageCache.

        This is the beginning of a prototype implementation of
        CSS Animation Triggers, as described by
        https://lists.w3.org/Archives/Public/www-style/2014Sep/0135.html

        In this patch we parse and resolve the value of a new
        CSS property "-webkit-animation-trigger". At the moment it
        only accepts one function value "container-scroll", which
        will trigger the animation at an absolute position within
        an element's scrolling container. We expect the syntax to
        change in the near future, as the spec is written.

        Allow clients to selectively disable plug-ins
        https://bugs.webkit.org/show_bug.cgi?id=142506

        Reviewed by Anders Carlsson.

        Add new functionality allow clients to declaratively disable individual plug-ins (in a manner that conceals them
        from the page). As part of this:

        1) Introduce the concept of web-visible plug-ins and related concepts, as distinct from the real underlying
           set of plug-ins.

        2) Where applicable, plumb additional information about plug-ins (specifically, bundle identification) deeper
           down the stack.

        3) Add generic functionality to PluginStrategy to support filtering plug-ins for visibility and introduce
           a concrete implementation thereof in WebPlatformStrategies in WebKit2.

        4) Add messaging infrastructure to allow clients to set and clear plug-in policies.

        While currently only used in a very limited manner, the new declarative plug-in policies are written generically
        so that they could be easily used in the future to reduce synchronous messaging to the client when loading plug-ins.
