TextComposition in the main process is destroyed when the main process sends eCompositionCommit(AsIs) to focused remote process. Therefore, ContentCacheInParent::mCompositionPendingCount is never 2 or more now.
It may cause ContentCacheInParent::Assign() setting older composition's start offset to current composition's start offset in the main process.
For making uplift the following patch easier, the wrong patch should be backed out first.

ContentCacheInParent::mPendingCompositionCount is now managed with composition events which TabParent received. However, TextComposition doesn't dispatch composition events after coming request to commit active composition. Therefore, composition is committed forcibly in a remote process over 255 times, the main process crashes.
It's the safest way to use TextComposition to manage ContentCacheInParent::mPendingCompositionCount.

This event is no longer necessary, since checking nsITabParent.hasPresented is enough to know
if we need to blank out the tab or not.

PBrowser::RequestNativeKeyBindings() is used only when somebody tries to
execute native key bindings for synthesized keyboard events. Therefore, it
doesn't need to retrieve edit commands for all editor types. Instead, it
should take the editor type and just return the edit commands for it.

This will return true if any of the frames loaded in the associated
TabChild have set at least one onbeforeunload event handler. If those
handlers are all removed, or all of the documents with onbeforeunload
event handlers are unloaded, this becomes false again.
Note that subframes that are sandboxed without the allow-modals
permission will not affect the hasBeforeUnload attribute, since
those iframes should never cause the beforeunload confirmation
dialog to display.

This patch replaces the usage of sNextTabParent pointer to store the next
PBrowser parent actor to be used by the next frame loader with the
following information:
* In the case where the content JS has requested a new tab, the ID of the
next TabParent will be stored on the <xul:browser> element.
* In the case where the content JS has requested a new window, the ID of
the next TabParent will be stored on the created nsXULWindow.
This piggybacks the sync message on the pre-existing
EnsureLayersConnected sync message pathway to the compositor.

The goal of this patch is to remove the call to the sync IPC
GetCompositorOptions message from TabChild::InitRenderingState. In order
to this, we have InitRenderingState take the CompositorOptions as an
argument instead, and propagate that backwards through the call sites.
Eventually we can propagate it back to a set of already-sync IPC
messages in PCompositorBridge that are used during layers id
registration (NotifyChildCreated, NotifyChildRecreated, etc.). Therefore
this patch effectively piggybacks the CompositorOptions sync IPC onto
these pre-existing sync IPC messages.
The one exception is when we propagate it back to the AdoptChild call.
If this message were sync we could just use it like the others and have
it return a CompositorOptions. However, it is async, so instead we add
another call to GetCompositorOptions here temporarily. This will be
removed in the next patch.

When we're animating, we tick the refresh driver. If that occurs in the parent process
when e10s is enabled, then we currently run TabParent::DidRefresh which does some
dimensions calculations and might send a message to the content process if the
dimensions have changed.
This was originally added to fix a B2G bug in bug 1153023. We don't need to do it
anymore, since we don't set CSS transforms on content browser windows.

The MozTabChildNotReady event is queued from the ProcessHangMonitor thread, and
that event might try to fire _after_ the main thread has received notification
that a layer tree was made ready. If that occurs, firing the MozTabChildNotReady
event makes no sense, as clearly the TabChild _became_ ready by the time the
event was about to be dispatched.

The machinery for suppressing the displayport during live resizes
was using the Observer service. However, in the case of multiple
browser windows, this meant that all the open browser windows would
have their displayport suppressed if *any* of the browser windows
was being resized. This was mostly ok, as the displayport suppression
would be turned off once the resize ended. However, the code to
kick off a repaint with the unsuppressed displayport would only get
triggered on one of the windows (whichever happened to process the
unsuppress message last).
This patch stops using the Observer service for the implementation
machinery, and instead locates the active TabParent of the relevant
nsWindow, and invokes the displayport suppression directly on that.
This fixes the repainting bug and also avoids unnecessarily
broadcasting the suppression/unsuppression notification to windows
that don't neccessarily need it.

Sending it back via the parent process ensures that it will take the same path
that regular touch events do, and so guarantees that the Tap event won't overtake
the touch events and get dispatched to content first.

There were a couple of problems when delivering tap gestures to content with
full zoom applied. One was that the ConverToGecko function converted the coords
into "CSS pixel" space by using the web content's CSS-to-LD scale, but also
applied that on the translation from the chrome area. Moving that conversion
to later in the process (after the coords got passed through TabParent::
AdjustTapToChildWidget) corrected that issue.
The other problem was that bits of code in APZEventState and APZCCallbackHelper
were using the widget->GetDefaultScale() value as the CSS-to-LD scale, but that
omitted the full zoom value. Getting the CSS-to-LD scale from the presShell and
propagating that through corrected that issue.

When PluginInstanceChild receives native key events, it should post the events to the chrome process first for checking if the key combination is reserved. However, posting all key events to the chrome process may make damage to the performance of text input. Therefore, this patch starts to post a key event whose key combination may be a shortcut key. However, for avoiding to shuffle the event order, it posts following key events until all posted key events are handled by the chrome process.
For receiving response from widget, this patch defines nsIKeyEventInPluginCallback. It's specified by nsIWidget::OnWindowedPluginKeyEvent() for ensuring the caller will receive the reply. Basically, the caller of nsIWidget::OnWindowedPluginKeyEvent() should reply to the child process. However, if the widget is a PuppetWidget, it cannot return the result synchronously. Therefore, PuppetWidget::OnWindowedPluginKeyEvent() returns NS_SUCCESS_EVENT_HANDLED_ASYNCHRONOUSLY and stores the callback to mKeyEventInPluginCallbacks. Then, TabParent::HandledWindowedPluginKeyEvent() will call PuppetWidget::HandledWindowedPluginKeyEvent().

Adds a new IPC message to the PBrowser protocol exposing
the number of tabs in the current window to the content
process. This allows the content process to reject window.resize*
calls in cases where there is more than one tab in the
window.
