This rejiggers a bit the way selection focus is handled so that focusing a
disabled form control with the mouse handles selection properly, and hides the
document selection and so on.
This matches the behavior of other browsers as far as I can tell.
Given now readonly and disabled editors behave the same, we can simplify a bit
the surrounding editor code.

nsFocusManager::GetFocusedWindow may return a window even if focus is actually inside an embedded OOP iframe.
Instead, use nsFocusManager::GetFocusedBrowsingContext, which always knows about the current focus across all processes.
If the focused context is in this process, we get its document and return it.

This code (and an upcoming dependent patch) is currently behind a pref which is disabled by default, as there is uncertainty as to how it might impact the Dev Tools A11y Panel.
The A11y Panel is currently a moving target due to ongoing refactor for Fission.
This pref should be removed once that groundwork is complete and the impact has been verified.
This patch also includes fixes to some ProxyAccessible methods which previously crashed when there was no parent, as is the case for top level documents.
Without these fixes, the Dev Tools A11y Panel would crash the parent process.

As the message above suggests this does two things:

Previously, the following scenario was possible:
1. aria-activedescendant is used on a menupopup to set a11y focus. When the event is processed, FocusManager::mLastFocus gets set accordingly.
2. aria-activedescendant on the menupopup is changed, so a focus event gets queued.
3. Before that focus event can be processed, the Accessible in (1) gets unbound from the a11y tree.
4. DocAccessible::UnbindFromDocument checks whether the Accessible is the last focus. As per (1), it is.
5. It then tells FocusManager to reset the active item, causing it to throw away the active item set in (2) and fire focus on the DOM focus (which is not the menupopup).
This breaks the new select dropdown implementation.
To fix this, we now set mLastFocus in DispatchFocusEvent (when the event is queued) instead of ProcessFocusEvent.
This way, we don't override a pending new focus change unintentionally.

Android does not currently have anything similar to a 'required' state
to indicate that a field or input is required before submission. In this
patch we append a localized "required" string onto the node's hint.
The hint typically has the description of the node. If the node is an
entry the hint will have its label followed by the description.

When window emulation is enabled, each tab document gets its own HWND.
OOP iframes get the same HWND as their tab document and fire events with that HWND.
However, the root accessible for the HWND (the tab document) can't return accessibles for OOP iframes.
Therefore, we must get the root accessible from the main HWND and call accChild on that instead.
We must do this in the parent process, but the tab document accessible is in the content process.
Although OOP a11y clients talk directly to the content process, the clients that need window emulation are in-process.
All in-process client calls get intercepted by AccessibleHandler, so we can deal with this forwarding in AccessibleHandler.

Windows programs run via Wine don't like Unix absolute paths (they look
like command line arguments), so we need to use relative paths.
Mingw already run fxc2 via wine, but for some reason it doesn't care
about the Unix absolute paths. genshaders does need some adjustements to
run properly with the real fxc.
Now, on actual Windows, because the temporary directory where
tempfile.NamedTemporaryFile creates files by default is not necessarily
on the same drive as where the command runs from, a relative path can't
be constructed. So we also force the temporary file to be created in the
current (obj) directory.
There is no similar concern for other files because we only go from
objdir to srcdir, and the build system already doesn't support both
being on a separate drive.
While here, flush stdout when the genshared script writes to it, so that
the messages are printed out immediately rather than randomly, later,
after output from subprocesses.

::marker content gets handled like text from any other CSS pseudo-class.
Therefore, using HTMLListBulletAccessible ends up duplicating the content already exposed in the a11y tree.
Now, we only use HTMLListBulletAccessible for nsBulletFrames instead of all marker frames.
As part of this, remove nsContainerFrame::GetSpokenMarkerContent, since we no longer need it to retrieve ::marker content.
The bulk of its other work was done by nsBulletFrame::GetSpokenContent, which we now call directly.
It also handled producing a default bullet character for list-style-image, but it makes sense for this to live in the a11y code.

Normally, XUL menupopups contain XUL menuitems, and XUL menuitems fire DOMMenuitemActive events from layout to manage a11y focus.
However, the new parent process select dropdown implementation uses a menulist containing div elements instead of XUL menuitems.
DOMMenuItemActive doesn't work for div elements because we check Accessible::ContainerWidget(), and that doesn't know to return the menupopup for div elements.
Since aria-activedescendant is the more web standard way to handle this, the new select dropdown implementation uses aria-activedescendant.
