This is an extension protocol that can be used for platform specific
API (ie. AccessibleWrap methods).
I'm not thrilled with the seperate constructor for the sub-protocol.
This means that the parent won't have the actor upon DocAccessibleParent
construction, and some timing bugs can arise because of the extra round
trip. It would be cool if both actors could be co-created, but that
would require ManagedEndpoint, and for PBrowser to manage them both. I
don't want to expose this to PBrowser.

Pruning these meant that `<span><br></span>` wasn't represented in the tree or rendered text at all.
This meant that lines were merged together in NVDA browse mode; e.g. in CI build logs on Gitlab.
The reason we started pruning these is that they were causing invalid line offsets to be returned for affected lines (bug 899433).
This patch also fixes this problem in HyperTextAccessible::FindOffset.

All calls to `profiler_add_marker()` (outside of the profilers code) are
now replaced by either:
- `PROFILER_ADD_MARKER(name, categoryPair)`
- `PROFILER_ADD_MARKER_WITH_PAYLOAD(name, categoryPair, TypeOfMarkerPayload,
(payload, ..., arguments))`
This makes all calls consistent, and they won't need to prefix the category pair
with `JS::ProfilingCategoryPair::`.
Also it will make it easier to add (and later remove) internal-profiling
instrumentation (bug 1576550), and to replace heap-allocated payloads with
stack-allocated ones (bug 1576555).

This patch does several things:
1. If there is a change to a host or a slot, check the slottable
elements to see if they are rendered in the tree. Remove them if not.
2. Check slot elements' fallback content if it is rendered and remove if
not.
3. Allow accessibles to be reinserted into a different parent or index.

Removing an Accessible removes descendants in the a11y tree.
However, there may be DOM descendants which have been relocated elsewhere in the a11y tree.
Their DOM nodes are now hidden as well, so we need to remove those Accessibles too.
In addition to Accessibles remaining in the tree when they shouldn't, failing to remove relocated Accessibles caused problems later on when a relocated Accessible was shown with new descendants.

We naively remove and then recreate accessibles when their content's
frame is reconstructed. By delaying the removal until we are certain the
content does not have a new layout frame, we can cut down on redundant
recreations.
When reconstructed content is re-inserted we can check it and its
subtree for missing frames and prune those accessibles from the tree.

This is the first step in making it possible to return remote WindowProxy
objects from window.open() and related APIs.
This patch also incidentally fixes a bug where getContentWindowOrOpenURI
returned the top-level browser window rather than the new content window when
passed OPEN_NEWWINDOW for the `aWhere` parameter. This was not the expected
behavior, and was a potentially major footgun for any new users who expected
to always get the content window for the URL they were loading, rather than
sometimes getting a chrome browser window instead.
For now, that case just returns null, which is only a minor footgun, rather
than the major one we had before.

Editor creates a `<br>` element when it's root element is empty.
Then, it's stored by `TextEditRules::mBogusNode` and used for checking
whether the editor is empty quickly. However, this `<br>` element has
`mozeditorbogusnode` attribute whose value is `true`. However, adding or
removing the attribute is not cheap and web apps can refer such illegal
attribute.
Therefore, this patch makes `HTMLBRElement` take a specific flag whether
it's a bogus node or not. However, this means that this hacky thing will be
exposed outside editor module. For making what is the bogus node clearer,
this patch calls the such `<br>` elements as "padding `<br>` element for
empty editor". So, this patch also includes a lot of renaming methods and
variables, and modifying related comments.

Normally, the OuterDocAccessible is created first and the DocAccessibleParent for a remote document is created after that.
So, we get the OuterDocAccessible and call DocAccessibleParent::SendParentCOMProxy when the DocAccessibleParent is constructed (BrowserParent::RecvPDocAccessibleConstructor).
However, sometimes, the OuterDocAccessible is created *after* the DocAccessibleParent.
This sometimes happens for extension popups, for example.
In that case, we previously never sent the parent COM proxy.
Aside from leaving the remote document with a null parent, this also meant we never sent any events for the document, since events are buffered for remote documents until the parent COM proxy is received.
This effectively left the remote document (e.g. extension popup) inaccessible.
Now, we also call SendParentCOMProxy in the OuterDocAccessible constructor.
Note that this doesn't result in duplicates because if the OuterDocAccessible was created first, there won't be a DocAccessibleParent for the remote document yet, so this code won't run.
That said, if the OuterDocAccessible is recreated (e.g. due to frame reconstruction), we may call SendParentCOMProxy again.
This should be okay, but it required an assertion in DocAccessibleChild::RecvParentCOMProxy to be tweaked.

Previously, we would always calculate the name for tr elements from their descendants unconditionally. Assistive technologies aren't using this information, moreover, it causes problems if the name gets too long, for example in layout tables.
We now only calculate the name if the tr element has an explicit ARIA role.

Previously, the target element for aria-activedescendant was retrieved by calling GetElementById on the owner document.
This meant that aria-activedescendant inside shadow DOM looked for ids in the owner document instead of the shadow DOM.
To fix this, use IDRefsIterator::GetElem instead.

On Windows, OuterDocAccessible::GetChildAt can return a proxy wrapper for a remote document.
These aren't real Accessibles and shouldn't be returned except to the Windows a11y code (which doesn't use eDeepestChild).
Calling ChildAtPoint on these will crash!
Therefore, just return null in this case.
