1. Register with the root document window's parent target, since this receives events for iframes and shadow DOM. (The root document itself doesn't.)
2. Hold onto the target node when scheduling processing of the DOM event, as GetOriginalTarget returns null when we process shadow DOM events async.

This can happen, for example, when GetAccessibleOrContainer is called within SelectionManager::ProcessSelectionChanged due to focusing a direct child of a shadow root.
In this case, the common ancestor is the shadow root itself.
Previously, we returned null in this case because GetFlattenedTreeParent doesn't work on the shadow root itself.
Now, we check if the given node is the shadow root, and if so, we use the shadow host instead.
This prevents the "We must reach document accessible implementing text interface!" assertion in SelectionManager::ProcessSelectionChanged when a direct child of a shadow root gets focus.

This is more consistent with how it works in GeckoView. We need to give
up this behavior because it reset the top-level caret position on each

The appropriate case is when placeholder is not used as the absolutely last fallback for the accessible name, and the input is not labeled by the same text as in the placeholder attribute itself. So a label and the placeholder text must be different for the object attribute to be exposed.
In addition, for ATK, placeholder is being renamed to placeholder-text to comply with the platform specification.

This patch takes care of a bunch of issues and does some cleanup:
* We rename mscom::MainThreadRuntime to mscom::ProcessRuntime, as the latter
is a more accurate name going forward.
* We make ProcessRuntime aware of the Win32k Lockdown process mitigation
policy. When Win32k is disabled, we perform process-wide COM initialization
in the multi-threaded apartment (since we cannot create an STA window).
* We refactor the mscom apartment region stuff to enable the Win32k lockdown
pieces in ProcessRuntime.
* We move some Gecko-specific stuff into MOZILLA_INTERNAL_API guards so that
ProcessRuntime is usable outside of xul.dll (I will be needing it for the
launcher process).
* Another thing that might happen with the launcher process is that, under
error conditions in the launcher, we create a ProcessRuntime object on a
background thread for the purposes of telemetry logging, but we also allow
the main thread to proceed to start as the browser. This could result in a
scenario where the main thread, as the browser process, is attempting to
instantiate its ProcessRuntime and ends up racing with the launcher process's
telemetry thread which has its own ProcessRuntime. To account for this
situation, we add mutual exclusion to the process-wide initialization code.
We host this part inside mozglue since that state is shared between both
firefox.exe and xul.dll.
* We clean up ProcessRuntime::InitializeSecurity by using Vector to set up
the EXPLICIT_ACCESS entries.
* We remove mscom::MainThreadClientInfo and replace it with a direct call to
CoGetCallerTID
* We revise all references to this class to use the new name.

When returning the column or row index of a given cell, guard against the column count being 0 or the given index being out of bounds of the current grid or table. The MSAA code already did this previously, but now the upper bounds check has been moved to the base classes and an additional guard for the column count been put in place so a division by 0 crash canot happen.
A return value for RowIndexAt and ColIndexAt of -1 indicates an error condition. ATK will automatically deal with this, and the IA2 code has been adjusted to check for this and return an invalid argument error in such cases, too.

If all parts of a table are non-standard display types, like all elements being display:block;, we weren't properly determining table cell indices because we weren't always taking into account thead, tbody, or tfoot elements. This patch:

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

We only use the handler for specific interfaces such as IAccessible* and IAccessibleHyperlink.
For interfaces which don't use the handler, we currently write an empty payload, but this still adds bytes to the stream.
This seems to break marshaling such an interface in a VT_UNKNOWN in a VARIANT.
To fix this, just don't write any payload at all when we aren't using the handler for the target interface.

Unfortunately, there's no existing equivalent in nsIDOMXULSelectControlItemElement.
radiogroup is the only element that needs this, so a new interface has been created for it.

Previously, if we had children a, b, c, and d, then removed b, the group position for c and d would potentially be marked as dirty, but a would not. This caused the check for the availability of previous group info to return outdated information.
This patch now always forces the update of all children's group position when a children move has occurred, since it potentially affects all the children, not just the ones after it. In addition, accGroupInfo::Update() now checks if the previous and next siblings that are being used as shortcuts have dirty group info, and are being used only if they do not.
