This makes Gecko conform to the newly documented expected behavior of ATK.

1. When role="document" is (redundantly) used on the body element, still expose the URL via accValue, just like we do for role="application".
2. Expose ROLE_SYSTEM_DOCUMENT for role="document" (rather than the string "document") as per the spec. (Chrome already does this, so I don't expect backwards compat problems with clients.)

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.

When getting the cell-index object attribute, now take into account that the row index might be invalid, and bail if that's the case. This should prevent negative index values which were one of the causes of Occasional crashes on Linux with weirdly formed tables like in Gmail.

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:
* Exposes non-standard tbody, tfoot and thead elements as groupings, similar to ARIA rowgroup.
* Adjusts the one instance in nsAccessibilityService::CreateAccessible that didn't account for the table not being the direct parent of the row node, but the grandparent instead.

After the fix for bug 646216, we no longer create divs with no text and only a br element for a line break. This breaks blank lines in contentEditables such as Gmail.
To fix, always create accessibles for divs if such a div contains a br element either as its first or last child.

Relevant divs are:
* Those that have an ID attribute. This is important so anchors still work.
* Those whose first or last child is a text-only node.
* Those whose first or last child has an inline frame.
We now discard divs that are not display:block; or display:inline-block;. We also discard divs that are part of an anonymous subtree.
We stop creating divs from the eHyperTextType frame type alltogether.
Note that because of shadow DOM properties in the video controls, two additional divs with IDs require role="none" in the media controls widget code.
