Chrome prunes the subtrees of links and headings (with single text leaf
children) and we mimic this in Gecko. The problem is that sometimes a
heading can be a child of a link, and it would be impossible to reach
when navigating by headings.
The main reason we mimiced chrome is because we would getthe name of the
node and its subtree uttered, so you would hear the name of the node
twice. By using contentDescription we can suppress the subtree from
TalkBack's utterance and preserve the node's children for heading
navigation.

We replace the a11y telemetry thread with a call to the new
`NS_DispatchBackgroundTask` infrastructure. We use `NS_DISPATCH_EVENT_MAY_BLOCK`
because the task performs some I/O to load the instantiator's version info.
I also took the opportunity to eliminate some redundant copying.

`nsRange` instances are allocated a lot in the heap especially by editor and
spellchecker. The allocation cost is too bad for benchmarks. Therefore,
we should reuse released instances as far as possible. For managing it in
static factory methods of `nsRange`, we need to hide `nsRange` constructor.

Which I really didn't feel like digging into.
* I had to restore the order of TrustOverrideUtils.h and related files in nss
because the .inc files depend on TrustOverrideUtils.h being included earlier.
* I had to add a missing include to RollingNumber.h
* Also had to partially restore include order in JsepSessionImpl.cpp to avoid
some -WError issues due to some static inline functions being defined in a
header but not used in the rest of the compilation unit.

On Windows, if the top level document hasn't received its parent COM proxy yet, sending constructors for child documents will be deferred.
If an OuterDocAccessible for an OOP iframe is created inside a child document before its constructor is sent, we must also defer the call to BrowserBridgeChild::SendSetEmbedderAccessible.
previously, we tried to send the embedder before the document constructor was sent, causing a crash.

After bug 981248, <input type="number"> no longer has an anonymous text input.
Instead, the <input type="number"> itself manages the text.
Previously, the a11y code which fired value change events for text changes only did this for combo boxes and role ENTRY.
This meant a value change event was no longer fired for <input type="number">.
This condition has now been extended to include role SPINBUTTON.
This fixes reporting of <input type="number"> changes for JAWS.

Previously, when opening the dialog, we only waited for a reorder event.
This could mean we programmatically closed the dialog before it was ever focused.
That in turn would mean that focus would never be fired on the previous window when the dialog was closed, causing the close dialog test to time out.

This is an alternative to carrying a revert of the offending changeset, since the bug doesn't show hope of a fix anytime soon, or maybe ever. This way we don't have to keep rebasing the patch as we pick up new clangs, and developers don't have to remember to apply the patch when building a local compiler.

Make -moz-box be block-outside, and -moz-inline-box be inline-outside, instead
of the bespoke thing we have now.

Talkback users expect that when you navigate past the end of the text in a node, Talkback will move into the next node and navigate there.
However, even though text navigation is async (client performs an action on the focused accessible and then waits for a text traversal event), firing a traversal event with a different accessible from the focused accessible is not supported by Talkback.
Firing a11y focus on the new node (as we did previously) doesn't fix this, but instead causes the entire node to be reported, among other weird behaviour.
1. Don't fire a11y focus for text traversal.
Aside from Talkback reporting the entire node, this was also confusing Talkback, causing it to try to navigate several times into the new node.
2. When navigating text, cache whether we're at either edge.
We do this because we need to be able to synchronously query whether we're at the edge, but we do navigation async.
Special handling is needed for words at the end because words don't include trailing space.
3. When performing a text navigation action, check if we're already at the edge using the cache described above.
If we are, synchronously return false, as Talkback expects.
Talkback will then move to the next/previous node itself and navigate the text there.

For paragraphs, divs, spans, etc., a11y focus on Android goes to text leaf Accessibles, rather than to the HyperTextAccessible container.
This does make sense, as these containers frequently embed other content, so the text needs to be reachable as a separate item.
However, previously, performing text navigation on these text leaf Accessibles returned the HyperTextAccessible parent.
This isn't supported by Talkback, and even if it were, it causes other problems; e.g. a11y focus being lost if the user was focused on a child other than the first child of such a container.
Therefore, if text navigation was performed on a text leaf Accessible, we now return a result within the text leaf Accessible if possible, rather than the HyperTextAccessible.
1. Make AccessibleWrap::GetTextContents support text leaf Accessibles (for both local and remote proxied Accessibles).
This is used when providing text for text traversal events.
2. When navigating text on Android, we use Pivot::Next/PrevText.
However, this will always return a HyperTextAccessible, even when starting on a text leaf.
Therefore, if the result from Pivot::Next/prevText resides entirely within the same text leaf, translate the offsets from the HyperTextAccessible so they're relative to the text leaf and return the text leaf.
3. Pivot::Next/PrevText already supported starting from a text leaf Accessible.
However, they ignored the offsets, which meant that navigating from a text leaf would always navigate to the start/end of the text leaf.
Now, if a text leaf is passed to Pivot::Next/PrevText, the offsets (if specified) are translated to the HyperTextAccessible parent first.
4. Adjust the existing character/word/line tests so they ensure that navigation returns the node that has a11y focus; i.e. the text leaf.
